The DEWALT DWA3PH2IR5 is a pack of five 3.5″ Impact #2 Phillips bits for anyone who drives Phillips screws with an impact driver. It is a basic consumableand the value is in having spares in the bag. I can’t speak to how long these last, but the format fits the job.
The specs that matter are the #2 Phillips tip, the 3.5″ length and the five bit count. The extra length helps you reach recessed screws, but a long bit can wobble if you push at an angle. The description says nothing about steel or finish, so I won’t guess.
Quick verdict: A simple five pack of long #2 Phillips impact bits that makes sense if you go through bits.
- Best for: Techs who need spare #2 Phillips bits with extra reach.
- Skip it if: You need a different tip size or want published steel details.
- Key spec: 3.5″ #2 Phillips, 5 pieces.
DEWALT DWA3PH2IR5 Specs and What Comes in the 5-Piece Pack
This pack holds five 3.5″ impact #2 Phillips bits. That is all the listing tells us, so treat it as a bag of bits and nothing more. No case or holder is mentioned.
- Quantity: 5 bits in 1 pack
- Length: 3.5 inches
- Tip: #2 Phillips
- Type: impact bit
- Origin: manufactured in China
#2 Phillips is a common size on panel screws, cabinet covers and disconnect boxes, so it is a tip you go through. The 3.5″ length gives you more reach than a short insert bit. That helps with recessed screws and keeps your hand back from the chuck. Five bits means you have spares in the bag when a tip rounds off, which Phillips tips do. The listing says “easy to use” but gives no steel grade, hardness or torque rating, so I won’t guess at those.
How Well Does a 3.5-Inch Impact Phillips Bit Resist Cam-Out?
The listing says nothing about tip geometry, coatings or steel, so I can’t tell you how well this bit holds a screw. It does say these are #2 Phillips bits, 3.5 inches long, sold as a five piece pack and made for impact use. That is enough to talk about what drives cam-out on a real job.
Most cam-out comes from poor fit and technique, not the brand on the bit. A #2 tip only seats right in a #2 recessand a worn or soft screw head will let any bit climb out. The 3.5-inch length gives you reach, but a longer bit flexes more when you lean in at an angle. Here is what I would check on any bit in this class:
- Tip wings are sharp and square, with no rounded corners
- The tip seats snug in a #2 screw with very little wobble
- The bit sits straight in the driver with no visible runout
- The tip is retired once it looks polished or chewed
A five piece pack helps here. When one tip rounds off, swap it out instead of fighting it, because a worn bit strips screw heads fast. Keep the bit square to the fastener and push firmly before you pull the trigger.
Is the DWA3PH2IR5 Tough Enough for Daily Jobsite Use?
The detail that matters most here is that these are sold as impact bits. A 3.5″ #2 Phillips bit in that class is meant to be driven by an impact driver, which hits screws hard and fast. The listing does not name the steel or any coating, so I can’t tell you how long they last.
On a jobsite, Phillips bits tend to fail in two ways. The tip cams out and rounds offor the shank snaps under a hard hit. Five bits in the pack gives you spares, which helps when one wears out mid-job. The listing says “easy to use,” but that is a general claim and not a durability spec.
- Tip fit: the bit should seat snug in the screw head with no wobble.
- Impact marking: check the bit itself when the pack arrives.
- Length: 3.5″ gives extra reach, but a longer bit can flex more if you lean on it at an angle.
- Retire early: toss any bit with a rounded tip before it chews up a screw head.
Will These Bits Fit Your Impact Driver or Drill Chuck?
The listing describes a 3.5″ impact bit in #2 Phillips, sold as a 5 pack. It does not state the shank type or drive size. Check the packaging before you count on a fit.
The “Imp” in the name points to impact driver use. That is where a bit like this belongs, since a regular bit can chip or snap under the hammering of an impact driver. Here is what I would check before it goes in the chuck:
- Shank: Confirm it is a hex shank that clicks into a quick-release impact chuck.
- Drill chuck: A three-jaw chuck can clamp a hex shank. Center it and tighten it hardor it will wobble and slip.
- Length: At 3.5″ it reaches into recessed spots. A longer bit also flexes and wobbles more in a drill than a short one.
- Tip size: This is a #2 Phillips. Match it to the screw head, because a #1 or #3 screw will not seat right.
A loose fit is what chews up screw heads. If the bit rocks in the chuck or sits shallow in the screw, stop and swap parts. Forcing it costs you more time than a fresh bit does.
DEWALT Impact Bits vs Standard Phillips Bits for Driving Screws
The main difference is the driver each bit is built for. An impact bit like this #2 Phillips in 3.5″ length is made for an impact driver, which adds sharp hammering blows to the rotation. A standard Phillips bit is made for steady torque from a drill or hand driverand it can chip or snap under impact.
That matters on HVAC work. Driving sheet metal screws into a unit panelor long screws into framing for a line set bracket, puts a lot of shock on the tip. A bit not built for it cams out, chews up the screw head and leaves you with a stripped slot. How well any impact bit holds up still depends on the steel and how well it fits the screw.
- #2 Phillips tip, a common size for general screws
- 3.5″ length, which helps reach screws set back in a panel or a tight spot
- 5 bits in the pack, so you have spares when one wears out
- Impact designation, meaning it is meant for an impact driver and not just a drill
Keep standard bits for light drills and hand drivers where there is no hammering. Use impact bits whenever the impact driver comes out.
Which Jobs and Users Suit a 3.5-Inch PH2 Bit Best?
The 3.5-inch length is the main reason to pick this bit. It reaches screws set back in recessed spots, like those on equipment cabinets, panel flanges and disconnect covers, where a short insert bit leaves your driver body hitting the surface. If most of your screws sit flush and open, the extra length adds little.
The #2 Phillips tip is the size you will meet most often on general fasteningand the impact rating means it is meant for an impact driver instead of a light drill. The five-piece pack suits anyone who loses or wears out Phillips bits regularly. Phillips tips cam out when they wear, so spares matter more than any single bit.
- Good fit: service techs and installers who drive #2 Phillips screws in hard-to-reach spots.
- Good fit: maintenance and general trades users who want spares in the truck or bucket.
- Poor fit: tight enclosures where a long bit and driver will not line up straight.
- Poor fit: hex-head, Torx or square-drive fasteners, which need a different bit.
The description calls it easy to use, which is about what you want from a basic bit. Match the tip to the screw head and keep the driver square to the fastener.

Frequently Asked Questions
How many bits come in the DEWALT DWA3PH2IR5 pack?
The DEWALT DWA3PH2IR5 comes as a 5 piece pack. The listing shows 1 pack, so you get five 3.5 inch impact #2 Phillips bits per purchase. Bits wear out and get lost on jobs, so a few spares help. Check the listing before ordering to confirm the count and the packaging.
Is a 3.5 inch bit like the DEWALT DWA3PH2IR5 good for reaching recessed screws?
A 3.5 inch length can help with reach, but the description says little else about intended jobs. Longer bits let you get past brackets or into recessed spots and keep your hand back from the work. The description does not list shank or torque details, so check the listing or DEWALT before you count on it for heavy fastening.
Is the DEWALT DWA3PH2IR5 an impact driver bit?
The listing calls it a 3.5 inch Imp #2 Phil Bit, which points to impact driver use. The description does not list shank type or torque rating, so confirm fit on the listing or with DEWALT. Also match the bit to the screw. A #2 Phillips bit belongs in a #2 Phillips recess.
Where is the DEWALT DWA3PH2IR5 impact Phillips bit made?
The description says the DWA3PH2IR5 is manufactured in China. It also lists the product type as tools and calls it easy to use. It gives no steel or heat treatment details, so I can’t speak to durability from the listing. For more specs, check the full product details or contact DEWALT.
What is the warranty on the DEWALT DWA3PH2IR5 Phillips bits?
The description does not give a warranty length for the DEWALT DWA3PH2IR5. Check the listing or DEWALT directly before you buy. Keep your receipt either way. Bits are wear items, so ask whether the coverage applies to normal wear or only to defects.
Final Verdict
This is a basic 5 pack of 3.5 inch impact #2 Phillips bits, made in China. The listing gives no details on steel, coating or torque rating, so I can’t tell you how long they last. What I can say is that the length and the #2 Phillips tip suit deck screw work, where you need reach and a lot of driving. Impact bits are the right class for that job.
It fits a homeowner or serious DIYer building or fixing a deck. It also fits a pro who wants cheap spares in the truck. If your deck screws are Torx or square drive, look elsewhere, since this is Phillips only. Same if you want published durability specs, because the listing gives none. Bits are a consumable. Buy them that way and keep a spare pack handy.
