We try out the Metal Plus cutting wheel from OK Diamond, and we even compare it to the best abrasive wheel as well. #sponsored OK Diamond provided their Metal Plus cutting discs for us to try. This Metal Plus wheel will not degrade even after hundreds of cuts and the risk of fragmenting is much less. Even after just thirty cuts, the abrasive wheel in our test was starting to drastically shrink in diameter. You can get these OK Diamond wheels on Amazon at the link below.

How do you cut steel and other Metal Products you use an angle grinder with An abrasive disc We've got another idea for you Just a few weeks ago this company Reached out to us and asked if we would Try their metal cutting blades and said Hey we're fine with you comparing it to Whatever you do just use it in your shop And tell us what you think about it and This is the okay Diamond metal plus Cutting blade now they sell it in a four And a half inch version they also I Believe have a four inch version and Then you can also get the three inch Version as well for your smaller cutting Tools which is is great to know anyway They sent us several discs and said have At it so let's do that let's dive in Take a closer look at this wheel then We'll actually use it on several Different tests and then we'll come back And talk about pricing and what we Thought of it well as we mentioned OK Diamond actually reached out to us and Asked if we would try their cutting Blades and we shared with them that we Typically use an abrasive blade when We're doing fabrication when we're Cutting steel and and different types of Product and they said that's fine we've Got you know a new blade Aid and we feel Like that you might like it and they Gave us some kind of characteristics to
To look for to differentiate between Their cutting wheel and the typical Abrasive blade so that's what we're Going to do and by the way this is not Some piece of junk abrasive blade we're Going to compare this against this is we Think one of the best blades out there We get it from our welding supply house And typically if you want good products When you're doing metalworking go to the Welding supply place they're not going To put stuff on their hooks that the Fabricators are not using and this is Their Sait z-tec disc and it's just a Great cutting cutting wheel but we're Just going to uh we're going to use this On some different things and put it head To head and see what we think about it And you'll be along for the ride let's Get started Ready Something you do have to consider Especially in a shop environment is Safety and the fact that a metal wheel Like the okay Diamond metal plus it has Virtually zero Flex at all and is not Going to be bothered when it's tweaked a Little bit one way or the other as well As drops so absolutely no flex in the Metal plus blade whereas your typical Abrasive blade there is going to be some Flex and you can even fragment this Thing as well so it's not like this Thing is indestructible and at 10 000
RPMs that becomes projectiles and even When you look at drops from a grinder And you're not going to have any issue With the metal plus blade whereas with An abrasive blade We already blew a chunk out of that one On one drop And that's going to continue to get Worse and that's going to become a Problem because now again we fragmented It and that's going to continue to come Apart the more we cut First up is we've got a simple piece of One inch conduit on here and we're just Going to make a few Cuts in this and see What we think with the okay diamond Wheel and by the way the grinder we're Using is the flex 24 volt brush so it's Got a 10 amp battery on it or 10 amp Hour battery on here so it should be Able to last several cuts and should be An RPM that's pretty typical to what You're seeing you know 8 500 to 10 000. Here we go We'll make another pass Foreign So the edge of that wheel is a hundred Degrees 101 Yeah it's about 102 105 is the hottest I'm seeing Now it looks like that conduit is about 170 Yes they're pretty warm on the end there Which I would expect we just made
Several cuts on it You can see I'm holding the blade All right we've got some typical one Inch conduit here and we've got an Abrasive blade on here make a few cuts Foreign Okay after a few Cuts looks like the Edge of that wheel is about 115 degrees Maybe a little hotter yeah it looks like I got like 138 142 On that wheel So right at the edge of that we're Definitely 130 140 degrees and On the conduit Yeah 190 185 190 degrees on the end of that Conduit Let's try One of the okay diamond wheels We'll let this cool off a minute Okay let's check this and yeah we're About down to Ambience about 90 degrees It's not quite 90 in the shop but still I think we've got a good true reading Here between 90 and 100 degrees and now Let's use the OK Diamond will and see How hot it gets I'll make three cuts on This as well Foreign Awesome Foreign Okay let's read the will Looks like right at 110 degrees Right on the edge
Yeah just 110 112 degrees is the hot spot 106 toward the Hub but right along the Edge I'm getting Uh there's a 116 it's the hottest I got So a little bit cooler and you can see Here I can put my handle here No problem at all it's not burning my Hand it's definitely warm but it's not Going to burn my skin Now let's take a reading here 130 140. So it looks like it cuts a little cooler Than the abrasive wheel does So again 130 degrees there and that Would probably probably on both of them Would continue to compound but Definitely seeing a difference as far as Cutting the metal as far as the Temperature goes Foreign We've gone to a little bit smaller of a Pipe but more of a construction type or Fabrication type of metal so we've Basically got an eighth inch wall one Inch piece of tubing so we're going to Make a couple of cuts on this Foreign So still about 110 degrees on the edge Of that wheel And we're Looks like we're a little over 200 Degrees A little more aggressive on that cut
Putting a little force on it so looks Like 190 200 degrees so that that's Definitely going to burn you if you Touch that But let's throw the abrasive on and see What we think Again you're saying hold the blade it's Not burning me Foreign 25 130 degrees there on the edge of that A little bit hotter than the 140. it's About 140 degrees on the edge of that Yeah so definitely a little bit warmer Looks like it's cooling off pretty Quickly though and then as far as the Metal goes yeah we're pushing Still pushing you know 180 190 Um On this one as well So it looks like as the metal is getting Thicker it might kind of even out as far As temperature of the cutting surface Because it's probably taking the same Amount of energy to cut through that Let's make a few more cuts Foreign Okay I'm definitely noticing something Uh look at the shower of Sparks on this Cutting wheel So I'm getting tons of Sparks out the Back side I'm getting tons out the tube And then I'm even throwing some forward As well But just a huge shower of Sparks I'm
Curious Thank you Even though we're still getting a good Amount of Sparks it's definitely Less on The OK diamond wheel definitely less Foreign So we've got some all thread in there Something pretty typical in construction That you would be cutting let's try that Foreign The same stuff Foreign So I think the abrasive wheel is faster When it comes to the solid stuff in fact I know it's faster I can just tell about The feel and by the look but we're Definitely throwing a lot more showers Than with the metal cutting wheel and Again this is staying quite cool now When I first took it off it was pretty Warm but now it's already cooled off Of course this doesn't seem to retain Heat either on your abrasive disc but One thing I do notice Is Now my abrasive wheel is starting to Shrink so you can see there's some life Gone In that cutting wheel already All right well not that things are going To change much but we've got a piece of One inch square tubing again pretty Typical eighth inch wall on here let's Make some cuts
Foreign Foreign Let's cut it with the abrasive wheel Thank you The abrasive will definitely throws a Lot more Sparks And I've got one more thing I want to Point out here in just one moment and Again you can see How much that wheel is starting to Shrink now And that's going to happen faster and Faster the smaller that gets because it Compounds itself because you have less Surface area the smaller that wheel gets To make that same cut so therefore You've got more friction you've got more Heat all that's building out and Compounding on itself and eating away That will which gets in to my last point In just one moment here and we'll show You all right now this is a very Scientific test here as you can see by The cardboard box I mean you just don't Get these anywhere no here's our Point Here we're going to make several cuts And uh in this all thread let's just say Five we're going to make five cuts with The abrasive wheel we're going to look Closely at our spark Trail as well as We're going to try to capture as much of That shrapnel that's coming off that Wheel as we can in this box and then We're going to test something else about
The content of that shrapnel also so Let's get started so again five cuts With the abrasive wheel All right so there's five cuts one two Three four five I am not going to pick Those up as much as I'm tempted to At least without my glove So here's my point on this let me get Rid of these Out of the box here Those are warm even with the glove on All right Get rid of those and now you can see What we've left behind here Which is quite a bit now here's what I Want to test I've got a magnet I want to See So a lot of this Is metal but a lot of it isn't by the Way this is a rare earth magnet so it's Very strong and picks up about anything That's got any iron in it at all but What we've got left here is a ton of Stuff and even up here on this lid That does not contain any of that and That is that wheel going away so that Abrasive wheel is eroding and you know When you get those black boogers it's Not all metal and iron that's collecting In there you're actually seeing this Abrasive will degrade and that's going Airborne as well now let's see if we can Prove that by making Cuts with the other Wheel all right let's uh
Take our wheel off for the final time Put the OK diamond wheel on here Foreign And now we'll make the same amount of Cuts five cuts So five cuts through that as well Now I can tell you just by looking at it The the particulate that's in here looks Larger I know that sounds stupid but it Just looks like it has more body to it Which I think is probably more metallic But anyway here is the existing This is from the abrasive wheel and so I've got a clean magnet here And I know we didn't capture all this But I just wanted to See if there would be a difference And the abrasive will for some reason Seems to have a lot larger pile of of Debris not sure why maybe we captured More of it And again looks to be quite finer Than the metal cutting wheel or the OK Diamond wheel as well not exactly a Scientific comparison but just something I wanted to take a look at but you can Definitely tell there's got to be what Two times The particulate on the abrasive side as On the metal cutting wheel and again Just the Sparkle's different and the Particulate size is different as well And so here we are after all those cuts Using the same blades
Again you can see there how much smaller This is than when it started so at some Point this is going to be a throwaway Which is really not that far away Because as you know as you're cutting The more it gets in the way and you Can't make your full cut you can see When we were doing the one inch tubing Even with a full blade is a pain in the Tail but definitely when you start Getting that smaller disc it becomes More of a pain to finish those cuts and So you end up taking this off and Throwing it away even before it's time But it's getting close to that point now Or you can run it all the way down to That Hub but again that's going to Happen quicker and quicker and Just to show you here let's see if We've had anywhere on the diameter size And that's zero I mean I don't see any There's no size difference at all After those I don't know 40 50 cuts that We made on there and they're claiming 3 000 Cuts so you know who knows maybe Depending on what you're cutting but you Can definitely tell that even after Those You know 30 40 50 cuts that we made There's absolutely no size difference Whereas the abrasive wheel is definitely Starting to whittle away all right Here's the deal the OK Diamond metal
Plus Wheels they last a long time you Can make tons and tons of cuts with These we did not make 3 000 cuts to test That but do I believe it would make a Thousand Cuts yeah I probably will Depends on what type of material you're Cutting now is it faster than an Abrasive Blade no I don't think you're Going to find anything as far as cutting On an angle grinder that's faster than An abrasive blade however when an Abrasive blade does it wears away you Continually change them as well as they Can fragment and come all to pieces and That's not going to happen on the OK Diamond metal plus wheel again if you Don't care about any of that you just Want to continue to buy these wheels or Replace them all the time you can do That also All that particulate from this wheel is Going airborne we know this thing's Spinning at 8 500 9000 10 000 RPM and All of that stuff that this wheel is Made out of is going airborne and Probably going in your nostrils or in Your mouth or wherever else so not a bad Idea to wear a respirator either you Know about those uh you know black gooey Things you pull out of your nose after Grinding or welding all day anyway sorry To be kind of graphic with that Um anyway surprise for an abrasive will You're probably going to spend a few
Bucks a piece on it if you're buying it At the Box Store if you're going to your Welding store and buy them in bulk then You may be down to a couple of bucks a Piece or buying them online a couple of Bucks a piece but anyway you're going to Pay a couple to a few bucks a piece Sometimes I see them for five and eight Bucks a piece don't buy your wheels for That that expensive of price for the Okay diamond wheel I think you can buy One wheel for like 16 bucks on on Amazon You can also check out their website uh But and then you can I think you can buy A two pack for like twenty two dollars So you can definitely get that price Down and then you're not changing out The wheels all the time and it's going To last you a long time so be sure to Check it out also follow us on Instagram Facebook Twitter and even Tick Tock and If you don't mind when you hit that like And subscribe button if you haven't done So already and by all means if you hated Our video then give us a thumbs down but Would you let us know in the comments Why have a great day and keep smiling
