# Klein Tools 670-6 Rapi-Driv Screwdriver Review: Old-School tool, Next-Level Speed
I’ll be straight with you – I didn’t think a screwdriver was going to be the tool I got excited about this month. but here we are.
I picked up the **Klein Tools 670-6 Rapi-Driv Screwdriver** after one too many afternoons fighting through a stack of switch plates and light fixture terminals on a residential rewire job. You know the drill - or rather, you know the *grind*. Dozens of long-threaded terminal screws, one after another, your wrist burning and your patience wearing thin before you’re even halfway through the panel room. I needed something smarter, and klein’s Rapi-Driv caught my eye for exactly that reason.
Klein Tools has been in the game as **1857** – that’s not marketing fluff, that’s a legacy - and this screwdriver is a prime exmaple of why tradespeople still reach for their name without thinking twice. The 670-6 is built around a **crank-action handle design** that spins fasteners fast with one hand, a **3/16-inch cabinet tip** precision-machined for exact fitment on terminal block screws, and a **6-inch shank** with a heat-treated, chrome-plated blade built to resist corrosion and take a beating over the long haul. Oh, and it’s **Made in the USA** – assembled domestically and meeting or exceeding ASME/ANSI specs. That matters to me, and I suspect it matters to you too.
What I wanted to find out was simple: does that Rapi-Driv crank action actually cut down your time and fatigue on repetitive screw-driving tasks, or is it just a gimmick dressed up in klein’s trusted branding? I put it to work on the job site and in the shop, and here’s everything I found out.
Klein Tools 670-6 screwdriver Overview What This Classic Driver Brings to the Table
I’ve been turning screws for a long time, and I can tell you that not all screwdrivers are created equal. this Klein cabinet-tip driver is the kind of tool that makes you appreciate what a well-engineered hand tool can actually do. The Rapi-driv crank-action handle is the real story here – it lets you spin fasteners quickly with one hand, which means less wrist fatigue on jobs that demand repetitive driving, like wiring switch plates or hanging light fixtures with long-threaded terminal screws. That crank geometry isn’t a gimmick; it genuinely reduces the number of full rotations your arm has to make, and on a long day in the field, that kind of efficiency adds up fast.
| specification | Details |
|---|---|
| Tip Type | 3/16-Inch Cabinet |
| Shank Length | 6 Inches |
| Handle Type | Cushion-Grip Rapi-Driv Crank-Action |
| Blade Material | Heat-Treated, Chrome-plated Steel |
| Blade Retention | Double-Flange, Twist-Resistant |
| Country of Manufacture | Made in USA |
| Standards Compliance | Meets or Exceeds ASME/ANSI Specifications |
The cushion-grip handle deserves its own callout - it provides genuine comfort during extended use, not the soft-squishy-but-useless grip you see on cheap imports. You can actually bear down on it and feel the torque transfer cleanly through the double-flange blade anchor, which locks the shank inside the handle to eliminate that annoying twist-and-slip you get with lesser tools. The precision-machined cabinet tip fits terminal block screws like it was born for them, reducing cam-out considerably – and if you’ve ever stripped a terminal screw on a panel, you know exactly why that matters. The chrome-plated, heat-treated blade resists corrosion, which is a practical detail when you’re working in humid environments or leaving tools in a van overnight.
- Rapi-Driv crank action accelerates fastener engagement with minimal wrist strain
- Precision-machined tip reduces cam-out on terminal and panel screws
- Double-flange blade anchor delivers solid, twist-free torque transfer
- Cushion-Grip handle stays comfortable through long drives without slipping
- Heat-treated, chrome-plated blade built for long-term corrosion resistance
- Made in USA with over 160 years of Klein manufacturing heritage behind it
- Meets or exceeds ASME/ANSI specifications – not just a marketing claim
Compared to a standard flathead driver from a big-box house brand, this isn’t even a fair fight. The crank-action alone puts it in a different category for electrical work, and the fit and finish reflect the kind of quality control that Klein has been delivering as 1857. If you’re still white-knuckling a straight-handled cabinet screwdriver on switch plate jobs, you’re working harder than you need to. This driver is purpose-built, American-made, and worth every dollar for the tradesman or serious DIYer who values tools that actually perform under real conditions.
Built to Last How the 670-6 Handles Real job Site Punishment
Out on the job site,a screwdriver takes a beating - dropped on concrete,shoved into tool bags,used and abused across hundreds of installations. What separates a tool that lasts a season from one that lasts a career comes down to materials and construction. The heat-treated, chrome-plated blade on this Klein is no cosmetic touch - that treatment adds genuine corrosion resistance, which matters when you’re working in humid environments, near water service panels, or just sweating through a long summer pull. I’ve run cheaper screwdrivers where the blade started pitting or the tip mushroomed after a few months of terminal block work. That hasn’t been my experience here. The precision-machined cabinet tip stays true, reducing cam-out even when I’m pushing hard on stubborn screws in device boxes or light fixture mounting plates.
the engineering that really earns my respect is the double-flange blade anchor inside the handle. That’s the detail that makes or breaks a screwdriver under real torque loads. Without it, you get blade spin – that sickening rotational slip inside the handle when you’re cranking hard. Klein solved that with flanges that lock the blade in place, delivering a solid, twist-resistant connection that translates every bit of hand effort directly to the fastener. Pair that with the Cushion-Grip handle, and extended use on long-threaded screws through switch plates or junction box covers stops feeling like punishment. Compared to a standard Craftsman or even a mid-range Stanley, the grip comfort over a full shift is noticeably better – less palm fatigue, more control. Here’s a quick look at how the build specs stack up:
| Feature | Klein 670-6 | Wiha 32092 | Stanley 66-158 |
|---|---|---|---|
| Blade Material | Heat-treated, chrome-plated steel | Chrome-vanadium steel | Chrome-plated steel |
| Tip Type | Precision-machined cabinet (3/16″) | Precision cabinet | Standard cabinet |
| Handle Design | Cushion-Grip, Rapi-Driv crank action | SoftFinish ergonomic | Bi-material comfort grip |
| Cam-Out Resistance | High (precision-machined tip) | High | Moderate |
| Blade Retention | Double-flange anchored | Blade anchored | Standard insert |
| Made in USA | ✅ Yes | ❌ No (Germany) | ❌ No |
| ASME/ANSI Compliant | ✅ Meets or exceeds | ✅ Yes | ✅ Yes |
Klein has been building tools since 1857, and that legacy isn’t just marketing – it shows up in details like the double-flange construction and the commitment to keeping manufacturing stateside. This screwdriver meets or exceeds applicable ASME/ANSI specifications, which is the kind of assurance that matters when you’re signing off on electrical work.If you wont a cabinet tip driver that holds up to daily professional use without babying it, this one belongs in your bag.
That Iconic Handle Feel Grip Comfort and Control When It Counts
Let me be straight with you – after years of running screws all day on job sites, your hand will tell the difference between a handle that was designed by someone who actually uses tools and one that was clearly sketched out in a boardroom. This one falls firmly in the first camp.The Cushion-Grip handle is the real deal – it’s soft enough to absorb fatigue during extended use,yet firm enough to transfer serious torque without that sloppy,mushy feel you get from cheaper alternatives. When I’m working a panel full of terminal block screws or chasing down a run of switch plates, the last thing I want is a handle that’s fighting me.This one works with my hand, not against it.
What really sets the grip experience apart here is the Rapi-Driv crank-action design. Once you feel that spinning handle mechanism working under your palm, you’ll wonder how you ever tolerated a standard fixed-handle driver for repetitive fastening tasks. It lets you crank fasteners down with one hand at a noticeably faster pace, and the reduced wrist strain after a full day of use is genuinely measurable.The double-flange blade anchor eliminates any wobble or twist at the blade-to-handle connection - that solid, locked-in feel directly translates to more confident torque submission. Compare that to some of the budget cabinet screwdrivers floating around the trades, and the difference in control is night and day. Even stacked against comparable options from Stanley or Craftsman, the ergonomic advantage here is clear.
| Feature | Klein Rapi-Driv Cabinet Driver | Standard Fixed-Handle Cabinet Driver |
|---|---|---|
| Handle Type | Cushion-Grip with crank-action spin | Fixed rigid handle |
| Fatigue Reduction | High – single-hand crank motion | Low – full wrist rotation required |
| Torque Transfer | Double-flange, twist-resistant connection | Standard press-fit or epoxy bond |
| Grip Comfort (extended Use) | Excellent | Moderate to Poor |
| Cam-Out Resistance | High – precision-machined tip | Varies by brand |
| Made in USA | ✅ Yes | typically No |
Here’s what the handle truly delivers in practical terms when it counts most:
- Reduced hand fatigue during high-volume repetitive driving tasks like wiring devices and fixture mounting
- Confident grip purchase even with slightly damp or dusty hands on the job
- One-hand operation via crank-action, freeing your other hand to hold components in place
- Solid torque delivery with zero handle flex or blade spin-out at the connection point
- comfortable diameter that fits a working hand without cramping up during long sessions

Driving Performance Where the Cabinet Tip Truly Earns Its Keep
When you’re running a string of switch plates, wiring a panel, or chasing terminal block screws through a retrofit job, this is exactly where the Rapi-Driv mechanism stops being a novelty and starts being a genuine time-saver. The crank-action handle design lets me spin fasteners quickly with one hand – no flipping the screwdriver end-over-end, no awkward repositioning in tight boxes. On long-threaded screws like the ones you’ll find in light fixtures and terminal strips, I’ve clocked noticeably less time per fastener compared to a standard cabinet-tip driver. That compounds fast across a full day of work. And unlike a power tool eating into a battery, there’s no drain to manage here – just mechanical efficiency doing exactly what it’s supposed to do.
The precision-machined cabinet tip is where this tool genuinely earns its reputation on the job. Cam-out is a real frustration on terminal block screws – strip one of those and you’ve got a problem that eats far more time than you saved. The tip seats cleanly and holds without slipping, even when I’m pushing with some force behind it. The Cushion-grip handle plays into this too – it’s not just marketing language. During extended use on repetitive fastening tasks, the grip absorbs enough hand fatigue that I’m not white-knuckling it by the end of the run. The double-flange blade anchoring inside the handle means there’s no flex or twist at the connection point when I’m applying real torque, which is a detail that cheaper screwdrivers skip and you feel the difference immediately.
| Feature | Klein 670-6 (Cabinet Tip) | Stanley FatMax Cabinet | Craftsman Cabinet Tip |
|---|---|---|---|
| Tip Type | Precision-machined cabinet | Standard cabinet | Standard cabinet |
| Handle Design | Rapi-Driv crank-action | bi-material grip | Soft-grip standard |
| Blade Material | Heat-treated, chrome-plated | Chrome vanadium | Chrome vanadium |
| cam-Out Resistance | High (precision-machined) | Moderate | Moderate |
| Shank Length | 6 inches | 6 inches | 6 inches |
| Made in USA | ✅ Yes | ❌ No | ❌ No |
| ASME/ANSI Compliant | ✅ Meets or exceeds | ✅ Yes | ✅ Yes |
What seals it for me on performance is the build integrity behind the tool. The heat-treated, chrome-plated blade handles the corrosion exposure that comes with real job sites - condensation, wet hands, outdoor panels – without showing the surface rust that starts creeping up on cheaper blades after a few months. The double-flange blade anchor is a structural decision that pays off in torque transfer, not just longevity. For tradespeople running terminal block work, switch plate installations, or any task with repetitive long-thread fastening, this is the kind of purpose-built detail that justifies keeping a dedicated driver in your pouch rather than reaching for a generic one. If you want a screwdriver that’s been engineered for exactly this kind of work and has 160-plus years of manufacturing credibility behind it, don’t overthink it.

How the Klein 670-6 Stacks Up Against the Competition
When you’re stacking this Klein cabinet screwdriver up against the competition, a few things become immediately clear – and they matter a lot when you’re knee-deep in a panel install or running through a stack of switch plates on a commercial job. The Rapi-Driv crank-action handle is a genuine differentiator here. Most budget cabinet screwdrivers from house brands or offshore manufacturers give you a basic handle with no real ergonomic thought behind it. Klein’s design lets you spin fasteners fast with one hand, which cuts fatigue dramatically on long-threaded screws. I’ve used comparable options from Craftsman and Stanley, and while they get the job done, neither one offers the same one-handed crank efficiency that makes this tool shine on repetitive work. The Cushion-Grip handle also delivers noticeably better torque transfer and comfort during extended use – something you don’t fully appreciate until you’re an hour into a fixture rough-in and your hand still isn’t screaming at you.
| Feature | Klein 670-6 | Stanley 66-158 | Craftsman CMHT65074 |
|---|---|---|---|
| Tip Type | 3/16″ Cabinet, Precision-Machined | 3/16″ Cabinet, Standard | 3/16″ Cabinet, standard |
| Shank Length | 6 inches | 6 inches | 6 inches |
| Handle Design | Rapi-Driv Crank-Action, Cushion-Grip | Basic Comfort Grip | Soft Grip, No Crank Action |
| Blade Construction | Heat-Treated, Chrome-Plated, Double-Flange | Chrome-Plated, Single Anchor | Chrome Vanadium |
| Cam-Out Resistance | High (Precision-Machined Tip) | Moderate | Moderate |
| Made in USA | ✅ Yes | ❌ No | ❌ No |
| ASME/ANSI Compliance | Meets or Exceeds | Meets | Meets |
| Corrosion Resistance | High | Moderate | Moderate |
On the tip precision side, this is where Klein truly separates itself from the pack. The precision-machined cabinet tip fits terminal block screws and fixture terminals with a snugness that noticeably reduces cam-out – and if you’ve ever stripped a terminal screw inside a tight junction box, you know exactly why that matters. Competing tools at a similar price point often have tips that are close but not quite dialed in, leading to that frustrating slip under torque. the double-flange blade anchor also gives the whole tool a solid, twist-resistant feel that cheaper alternatives just can’t match – there’s zero flex or wobble when you’re really leaning into a stubborn screw.Add in the heat-treated, chrome-plated blade for long-term corrosion resistance, and this is a tool built to survive job site abuse, tool bag tossing, and years of daily use. For a hand tool that’s manufactured and assembled in the USA and backed by over 160 years of professional-grade craftsmanship, the value proposition is hard to argue with.

My Final Take Is This Klein Screwdriver Worth Adding to Your Kit
After putting this Klein cabinet-tip screwdriver through its paces on electrical panel work, switch plate installs, and terminal block connections, I can say with confidence – this thing earns its spot in my tool bag. The Rapi-Driv crank-action handle is the real standout here. When you’re running down long-threaded screws in light fixtures or switch plates all day, that spinning handle design lets you move fasteners fast with one hand while keeping your other hand free to hold components in place.It’s a legitimate time-saver, and after a full day on the job, my hand wasn’t screaming at me the way it does with a standard-grip driver. The Cushion-Grip handle deserves credit for that – it absorbs fatigue without sacrificing torque transfer, and on long runs of repetitive driving, that matters more than most guys want to admit.
The precision side of this tool is where Klein’s manufacturing legacy really shows. The 3/16-inch cabinet tip is precision-machined to drop into terminal block screws with a snug, exact fit – cam-out is barely a concern. The heat-treated, chrome-plated blade resists corrosion from sweat, solvents, and whatever else ends up on your hands during a job, and the double-flange blade anchor keeps the blade locked solid inside the handle with zero flex under torque. Compare that to budget screwdrivers where the blade spins inside the handle under load – there’s no comparison. Up against something like a Wiha or Wera in the same cabinet-tip category, Klein holds its own on tip quality and handle ergonomics, and it edges them out on price-to-performance for everyday trade use.
| Feature | Klein 670-6 | Wiha Cabinet Screwdriver | Wera Classic Cabinet Tip |
|---|---|---|---|
| Tip Size | 3/16 in. | 3/16 in. | 3/16 in. |
| Shank Length | 6 in. | 6 in. | 5.9 in. |
| Handle Design | Rapi-Driv Crank-Action | Soft-Finish Ergonomic | Kraftform Ergonomic |
| Blade Material | Heat-treated, Chrome-plated | Chrome-Vanadium | Chrome-Vanadium |
| Made In | USA | Germany | Germany |
| Cam-Out Resistance | Precision-machined tip | Precision-ground tip | Laser-tip surface |
| ASME/ANSI Compliant | Yes | Yes | Yes |
Bottom line – if you’re doing electrical work, cabinet installs, or any task that demands precision on slotted terminal screws, this driver is a no-brainer addition to a working tradesman’s kit. The Made-in-USA construction, six generations of Klein craftsmanship behind the design, and the practical advantage of that crank-action handle on long-threaded fasteners make this one of the smarter buys in the hand tool category. It’s not flashy, but it’s exactly the kind of tool that quietly makes your day easier – and that’s what matters on the job site.

What Pros and DIYers Are Saying
I spent a good chunk of time digging through reviews on this one, and here’s the honest truth – the Klein Tools 670-6 Rapi-driv generates some genuinely passionate opinions on both sides of the fence. You’ve got electricians and contractors who swear by it after years of daily abuse, and then you’ve got a smaller but vocal group pointing out some real gripes that are worth your attention before you pull the trigger.Let me cut through the noise.
What Reviewers Are Loving
The single biggest thing that keeps coming up – almost obsessively so - is the tip quality and how it holds up over time. Guys running this thing through hundreds of screws on commercial jobs report that the 3/16-inch cabinet tip stays sharp and true far longer than what they were getting from Stanley or Craftsman at a similar price point.One electrician mentioned he’d been running the same Rapi-Driv for over 14 months on daily panel work and the tip showed almost no cam-out wear. that’s the kind of real-world durability data I look for.
The Rapi-Driv mechanism is another consistent winner in the reviews. The ability to spin the handle cap with your palm while keeping your fingers on the grip for directional control genuinely speeds up repetitive screw-driving tasks – reviewers doing trim work, cabinet installation, and electrical rough-in all flagged this as a legitimate time-saver rather than a gimmick.One trim carpenter put it bluntly: “It’s the only screwdriver I grab when I’m setting 200 hinges in a day.”
Ergonomics hold up well under extended use too. The dual-material handle – hard plastic core with the softer overmold – gets consistent praise for not causing hand fatigue during long days. Reviewers doing 8-plus-hour shifts reported noticeably less palm soreness compared to older all-hard-plastic handles. that matters when you’re actually on a job site,not just doing a 20-minute DIY fix.
And yes – the Made in USA badge isn’t just marketing fluff here. Reviewers who’ve owned Klein tools for decades point out that quality control on the domestic-made pieces has stayed consistent even as other brands quietly moved production offshore and let tolerances slip.
Where Reviewers Are Pushing Back
It’s not all five stars and championship speeches, though. A recurring complaint I kept seeing was around the handle size feeling too bulky for tight spaces. If you’re working in a crowded junction box or a cramped cabinet corner, the wider Rapi-Driv handle profile can get in the way in ways that a slimmer customary handle wouldn’t. A few reviewers specifically said they keep a backup slim-profile driver for those situations.
There were also some scattered – but consistent enough to flag – quality control complaints about the Rapi-Driv spinning mechanism feeling loose out of the box. It’s not a widespread epidemic, but enough buyers mentioned receiving a unit where the palm cap had more wobble than expected that I’d pay attention to it. Most said it didn’t affect function, but it did affect the premium feel you’d expect at this price.
A smaller group of reviewers – mostly DIYers rather than pros – felt the price point was hard to justify versus a generic cabinet screwdriver from a big-box house brand. Fair point if you’re only driving a few screws a month. But if you’re a tradesperson putting serious hours on your tools, the consensus pretty clearly lands in Klein’s favor on value over time.
How It Stacks Up Against the Competition
Reviewers frequently compared this head-to-head with Wiha, Wera, and Milwaukee’s Cushion-Grip line. The Wiha and Wera comparisons are interesting - both brands get credited for slightly better ergonomic refinement and tip precision out of the box, but they come at a higher cost and aren’t made domestically. The Milwaukee comparison lands more favorably for Klein on tip longevity. Where Klein loses ground is on the premium feel of the handle mechanism versus Wiha’s build quality - reviewers who’ve used both tend to acknowledge Wiha edges Klein on fit and finish, even if Klein holds its own on raw durability.

Bottom line from the reviews: The professionals who put serious hours on this tool are overwhelmingly satisfied – especially those doing repetitive driving work where the Rapi-Driv mechanism earns its keep. the criticisms are real but narrow. If you’re a tradesperson or serious DIYer who needs a reliable, USA-made cabinet screwdriver for daily duty, the crowd is largely telling you to buy it. If you’re an occasional user or working in extremely tight spaces,you might want to weigh your options more carefully.
Pros & Cons
Pros & Cons of the Klein Tools 670-6 Rapi-Driv Screwdriver
Alright, let’s cut through the catalog copy and talk about what this screwdriver is actually like when you’re running it through your third panel rough-in of the day or swapping out switch plates on a 40-unit apartment walkthrough. I’ve put this thing through its paces, and here’s the honest breakdown.
|
✅ PROS |
❌ CONS |
|---|---|
| The crank action is a genuine time-saver. Not marketing fluff – when you’re threading long screws into terminal blocks or fixture straps, that spinning top handle actually eats up thread fast.Your wrist thanks you by lunchtime. |
Cabinet tip only – no versatility here. This is a single-purpose tool. If you grabbed this hoping it’d pull double duty as a slotted all-rounder on the job, forget it. It’s machined tight for terminal screws, and that’s it. |
|
The grip holds up after extended use. Two hours in on a repetitive wiring job, the Cushion-Grip isn’t slick, it isn’t cramping your palm, and it’s not digging in like some of the cheaper handles I’ve tortured myself with. legitimate ergonomic design, not a sticker on the side that says “comfort grip.” |
It’s a one-trick pony on the torque front. This is a hand screwdriver – there’s no clutch, no adjustable torque setting, no nothing. You’re relying on feel alone. On sensitive terminal screws,that’s actually fine,but if you’re used to a driver with more feedback,there’s a learning curve to not overtightening. |
|
The precision-machined tip actually means something. Cam-out on terminal screws is the kind of annoyance that makes you want to flip a panel. This tip seats properly, stays seated, and doesn’t slip.I’ve used enough garbage tips to know the difference immediately. |
Not a tool you can source replacement parts for. If the tip rounds out or the handle cracks, you’re buying a new screwdriver – full stop.Klein doesn’t sell replacement blades for this one. For the price point, it’s not a dealbreaker, but it’s worth knowing going in. |
|
Made in the USA and it shows. The chrome-plated, heat-treated blade isn’t going to rust out on you when you forget it in a damp toolbox over a wet weekend. Build quality is solid – this doesn’t feel like a tool that’s one drop away from falling apart. |
The crank can feel awkward in tight quarters. The Rapi-Driv handle is wider than a standard screwdriver by design - that’s how the spinning action works. But in a crowded junction box or a cramped panel, that extra bulk can become a legitimate problem. It’s not always your friend in confined spaces. |
|
The double-flange blade connection is bomber. No wobble, no twist-out – this thing transfers torque cleanly from your hand to the screw. I’ve snapped cheaper screwdrivers where the blade meets the handle. Not an issue here. |
Premium price for a manual hand tool. You’re paying Klein money for a screwdriver.Compared to grabbing a Wiha or even a Craftsman cabinet tip driver, you’re spending more.It earns that price tag in durability and function, but if you’re outfitting a whole crew, the cost adds up fast. |
|
Great value for the specific job it’s designed for. If you’re an electrician doing volume work – residential wiring, fixture installs, device rough-ins - the speed and fatigue reduction over a standard screwdriver pays for this thing in a single day of work. That’s not hype, that’s math. |
No magnetized tip. When you’re working in a box with one hand and trying to seat a terminal screw with the other, a magnetized tip would be a quality-of-life upgrade that’s noticeably absent here. It’s a real miss for the type of work this tool is built for. |
The Bottom Line on the Rapi-Driv
If you’re an electrician doing repetitive device and fixture work, this screwdriver earns its spot on your belt.The crank action is legitimate, the build quality is Klein-level solid, and the tip fit on terminal screws is the kind of thing you notice and appreciate every single time. It’s not a jack-of-all-trades tool and it doesn’t try to be – it’s a purpose-built weapon for a specific job, and it does that job better than anything else at this price in its class.
Where it stumbles is the lack of a magnetized tip, the bulkiness in tight spots, and the fact that it’s a one-way investment with no replacement parts available. But if you’re honest with yourself about what this tool is designed to do, those are trade-offs you can live with. I wouldn’t hand this to a general laborer as a daily driver,but for the electrician or finish tradesman who knows exactly what they need it for – it’s a buy,full stop.
Q&A
## Q&A: Klein Tools 670-6 Rapi-Driv Screwdriver - Your Questions Answered
—
**Q: What exactly is the “Rapi-Driv” crank-action, and does it actually save time on the job?**
A: yes, and it’s not just marketing fluff. The Rapi-Driv handle is designed to spin fasteners quickly with one hand using a crank-style action – think of it like a built-in speed boost without reaching for a power tool. I’ve used this thing on switch plates,light fixtures,and terminal blocks where you’ve got long-threaded screws that need a lot of turns to seat. That crank action chews through those rotations fast and keeps your wrist from dying after the tenth outlet box of the day. It’s a legitimate time-saver, especially on repetitive tasks.—
**Q: Is this a specialty screwdriver, or can I use it as my everyday flathead?**
A: It leans specialty, but it earns a permanent spot in your pouch either way. The 3/16-inch cabinet tip is precision-machined specifically for a tight, exact fit – we’re talking terminal block screws, switch plates, light fixture mounting screws, that kind of work. It’s not your go-to for backing out lag bolts or prying open a paint can lid. But if you’re an electrician, an HVAC tech, or a serious diyer doing finish electrical work, this thing will be in your hand constantly. It does one job and does it better than almost anything else on the market.
—
**Q: how does this compare to a standard flathead screwdriver from DeWalt, Milwaukee, or Craftsman?**
A: Honestly? There’s no direct apples-to-apples comparison as none of those brands make a crank-action cabinet-tip screwdriver like this. Standard flatheads from DeWalt or Milwaukee are solid tools, but they’re just static handles – you turn them the old-fashioned way. The Klein 670-6 gives you that crank-action speed advantage that none of those competitors match in this category. If you’re comparing build quality on a straight screwdriver, Klein’s chrome-plated, heat-treated blade and double-flange blade-to-handle connection put it ahead of most mid-range options. Klein has been doing this as 1857. That track record matters.
—
**Q: can this handle all-day use on a job site, or is it more of a weekend warrior tool?**
A: All-day, no question. I’ve put this through its paces on long fixture installs and panel work where you’re running the same motions for hours. The Cushion-Grip handle genuinely reduces fatigue – it’s not just a soft rubber sleeve slapped on there. It’s designed to give you grip and comfort simultaneously so you can keep driving without your hand cramping up. Klein builds these for professional trades use, not for the once-a-year homeowner. the chrome-plated, heat-treated blade is built to hold up to daily abuse, and the ASME/ANSI compliance means it’s been tested to standards that actually mean something.
—
**Q: Will the tip cam out and strip my screws? That’s my biggest frustration with cheap flatheads.**
A: That’s a real problem with garbage-tier screwdrivers, and Klein specifically engineered against it here. The precision-machined cabinet tip is built for an exact fit on terminal block screws and similar fasteners. Tight tip-to-fastener fit is the single biggest factor in preventing cam-out, and Klein nails it. I’ve had zero cam-out issues using this on the screws it’s designed for. Use the right screwdriver for the right screw – that’s the other half of the equation – and this tool will not let you down.
—
**Q: Is this actually Made in USA, or is that just a label?**
A: It’s the real deal. Klein manufactures and assembles the 670-6 in the USA, and they’ve been doing it that way for over 160 years. klein is a family-owned, family-run American company – they’re not outsourcing their reputation. you’re getting American quality control,not a tool that shipped in a container from overseas with a slapped-on sticker. That matters to me when I’m buying tools I rely on every day,and it should matter to you too.
—
**Q: What’s the warranty, and if something goes wrong, will Klein actually take care of me?**
A: Klein stands behind their tools. They back the 670-6 with a lifetime warranty against defects in material and workmanship – that’s what you expect from a professional-grade manufacturer,and Klein delivers it. In my experience, klein’s customer service is straightforward and doesn’t give you the runaround. A company that’s been family-owned as 1857 understands that their reputation is everything.They’re not going anywhere, and neither is your coverage.

**Q: Is the 6-inch shank long enough for most electrical work, or will I need a longer version?**
A: For the vast majority of electrical finish work – switch plates, outlet boxes, fixture mounting, terminal blocks – the 6-inch shank is the right call. It gets you into recessed boxes without the handle hitting the wall, and it’s not so long that it gets unwieldy in tight spaces. if you’re regularly working deep inside panels or need extra reach,klein does make the Rapi-Driv in other configurations,so check their lineup. But for everyday electrical work, the 670-6 is the sweet spot.
Our Verdict|Final thoughts|Bottom Line|The Toolman’s Take
Bottom line? The klein Tools 670-6 Rapi-Driv is a legit workhorse that earns its spot in your tool bag every single day.I’ve driven more screws than I can count with this thing - switch plates,light fixtures,terminal blocks,you name it – and it keeps delivering. The crank-action handle is a genuine time-saver, the cushion grip keeps fatigue in check on long runs, and that precision-machined cabinet tip stays put in the slot instead of chewing it up. That’s not a small thing when you’re deep into a job and working fast.
who’s this best suited for? Honestly, I’d say this one is squarely in the pro and serious DIYer camp. If you’re an electrician, a contractor, or someone who actually uses their tools hard and frequently enough, this is a no-brainer addition to your kit. The crank-action efficiency really shines when you’re cranking through repetitive fastening tasks – that’s where it pays for itself. A casual homeowner can absolutely use it and love it, but if you’re only driving a handful of screws a year, a standard flathead will do. This tool rewards the people who push it.
Made in the USA as 1857 – Klein doesn’t need a marketing pitch. Their reputation speaks for itself, and the 670-6 lives up to every bit of it. it’s built tough,it’s precise,and it’s backed by a company that’s been doing this longer than most tool brands have existed. I don’t throw the word “buy it” around lightly, but here? Buy it. You won’t regret it.
