It looks like the abrasive wheel leaves a smoother cut compared to the OK diamond blade leaves more of a burr

Looks like the abrasive wheel cuts faster and leaves a smoother cut. I’m not sold on those I’ve used a diamond blade and found it took a long time to cut through the material I was using

The abrasive disc is cutting all of the different materials a lot quicker, so I'm guessing it's eating up more material quicker causing more sparks. And as everyone else has pointed out, the abrasive disc leaves a cleaner cut. I'll stick with the abrasive disc! Thanks for the video, you saved me money.😅

Do you have a video on those vise-grip type pliers and holders? Never seen those but they look like a Great tool. Any info is greatly appreciated

I suppose it depends on the type of work you're doing, but the abrasive cutoff wheel produced a much cleaner cut, and although it's hard to see in the video, I'm assuming it has a narrower kerf as well. For metal fabrication work, I'd go with an abrasive cutoff wheel all day long.

What kind of clamp did you use to secure the pipe to workbench

I try to use cut off wheels as little as possible. I will plasma cut or us a cold saw. This seems like an improvement over an abrasive because there will be less abrasive dust in the shop getting in Precision parts Like the ways of a lathe or mill or the guide rails on the cnc machines

I'm impressed for all the demonstration that you did ..Thank you for sharing keep up the good work .

Definitely cool they both have their pros and cons. Something that i would keep my eye on.

Another thought on the resin bond abrasive blades-as they wear down you are BREATHING that fine dust and it gets EVERYWHERE.The carbide blade saws only make the coarse metal shavinglike"sawdust"That is easier to cleanup.

What clamps did you use in the video? Did you make them or purchase them? Thanks. Great video.

Didnt watch video yet but my experience with these types of blades is Pros- maintain full depth of cut through out life of blade, safer (wont shatter), good for thinner material, less wheel changes (longer life if not abused) Cons- slower cut (but maybe faster in very thin) cost (at least upfront), doesnt like material too thick (would stay under 1/4" thick in my opinion), cut not as clean, less sparks but get more actual metal shavings you get hit with would rather get hit with sparks in my opinion O and they def rebranded lenox metal max wheels lol. For me i primarily stick with abrasives but i always try to have one of these on the truck just in case as well.

The major benefit I see is safety. They last longer in theory but I find every diamond blade I have had other than tile saw blades stops cutting well after a few cuts. I'm always afraid of an abrasive wheel catching something, shattering and ending up in my gut or my face.

What type of table clamps are those?

Thanks for the info - very well done, sir.

Note that one can optimize very much the lifetime of an abrasive blade by paying attention to the cutting forces applied!!! In optimal conditions the grains should cut until they are dull, and then they should be released by the binding agent. These conditions can only be applied when paying very much attention to the applied forces. 90% of us work too aggressive with these disks. A colleague technician of mine was freaked on this. He never had the quickest cutting and deburring speed, but he did the most job on a day! His disks (from same make) did last on average 3 times longer. The others worked slower because they had to make more disk exchanges.

Looks like a good way to go. I'll be watching for them

I tried to find one of these in the UK years ago, could not. Can’t remember whyfor now. I’ll remember to look out for one. Now let’s have a look at that look at that uncuttable lock someone was making a pigs ear out of cutting a few weeks back !

Something I noticed the cut was much cleaner on the abrasive wheel

Was really hoping to see how it did on the M12 3" cutoff tool. Really wish Milwaukee would make a M18 version that has the power or the regular fuel grinder!

Id use the abrasive wheel for rough cut sruff, cutting off bolts, etc that doesnt require precision. I just bought one to try because it looked like something cool to try and I like the idea of it not shattering. For clean cuts that need little cleanup after, I will stick with abrasive discs. I think there is anplace for both in my shop amd Ill keep one on a grinder all the time. Thanks for the video

Clearly the abrasive wheel is faster and cleaner in its cut. They both throw enough sparks for any situation that spark would be dangerous. No matter what you are cutting, if it is work, you want things done quicker and cleaner. Also, If these things were sent to you out of the blue and you are not sponsored by them then don't make excuses for it's deficiencies. As for safety, If you use the tools properly you'll have no issues. I try to teach my new guys all the time how to use the cut off wheel correctly. I personally haven't broken a cut off wheel in over three years. In that instance I was rushing to finish the job.

Could you share where nose nifty vise grip bench clamps came from?

Hi. Can you tell me the name of those vice grip table adapters? I’ve been trying different search words but can’t find them for sale. Thanks

I would love to see weather the amount pf sparks becomes comparable if you speed the ok diamond wheel up so your getting the same cut time as a conventional wheel As its cutting slower its naturally going to produce less sparks as its removilg less meterial The only grinder i would consider using a diamond wheel for cutting would be a 230mm grinder as theee cu55ing discks tend to be thicker requiring more meterial to be removed per cut and the cost of blades is increased due to size also 🤔 But with a 4.5" 5" i want small 1mm disc fast and clean cut less prep time with a 230mm 9" i can run through rough stock

The M12 Fuel bandsaw is the best for cutting conduit and unistrut

Metal fab, I use abrasives a lot. If I need to cut something I don't usually resort to an angle grinder unless I don't have other options. I have a chop saw for cuts, plasma cutter etc.

The abrasive definitely leaves a smoother, better finish. I definitely would like to try it, but I'm not sold on it.

Hello! where can I get the set of pliers your using to hold the material you are cutting?

i like sparks and clean cuts. :) Diamond would probably work with more material types though. It would be a great backup. If the diamond wheel replaced 50 plus abrasive disks it might be worth a look as well.

What's the tool holding the vise crip

I use and love the Lennox “Metal Max” diamond cut off wheels. They look exactly like these in every way except the name. Same color, same graphics, literally same everything but the name. Are these just renamed Lennox Metal Max wheels?

I would like to know the brand of those locking pliers.

Another interesting think is that the abrasive wheels have a bend about halfway through, you can only cut material the thickness of the flat part up to the bend. While the metal wheels are flat all the way through so you can cut much deeper for the same diameter wheel.

Love the vid Tim. The editing was awesome buddy. Great job man

Thin abrasive disc. I have that diamond metal disc and it’s 3-5 times slower. I had to cut out some 1/4” steel and the diamond took forever. The diamond does cut cooler with less sparks

Do the clamps work only with the grip-on pliers or can you use any locking pliers?🎃🎃

the abrasive wheel cuts, sands and it looks to be thinner which gives cleaner and quicker cuts. they could adjust the metal wheel to do the same by changing the design a little. that's if you need that.

I've worked with a lot of different diamond saws and wheels. Here is the 411...diamond wheels will last much much longer as long as you don't abuse them. Apply very light pressure and let the wheel cut at the rate it wants to. As you push a diamond wheel harder, you start to dislodge the diamonds in the wheel. The wheels will cost more up front, but they will outlast the abrasive wheels by far. Of course, they cons, they do cut slower

Would like to have seen you cut some 0.090-0.156" plate or SS. Curious about blade wander/difficulty of cutting straight line & overall performance. 8-9 yrs ago, I got caught short on a metal roofing project & had to modify some precut 0.110" SS flashing. Was geared up for sheet metal, not steel fab. I had a worn out 7" diamond wet tile saw blade in the bottom of a tool box I'd taken off my saw when it started chipping glaze; still had visible diamond on it. 'Wonder if that'll cut stainless?' I threw it on my ancient beater Skil 77 worm drive that gets all the chit jobs & it got the job done w/ a bit of noise & some red hot slag. 77 didn't over heat & die, so it was a win. Got home, cobbled a compr'd air cooling line pointed at the cut point & started using it. I've cut 200-250 linear feet since then & the old dead blade is still workin'. A dead blade, designed for tile... I've been waiting for the diamond blade industry to catch up, & it looks like they're getting close. The OK blade design is very much like a masonary blade, which is interesting, & needs to improve, as well as grit size needs to drop for better cuts. I have an 8" beam saw I made from a '50's era cast iron DeWalt radial arm saw, (no radial mvmnt, just vert), I use w/ carbide & 0.060" abrasive blades. When the 0.060" abrasives get to 5", they go to the side grinder, then to the die grinder. Even have some 10" 0.060's that've started the same cycle on my table saw, (cut some mighty fine, straight & perpendicular, finish cuts to close dimension in 0.50" A36 tool steel w/ it.) On both the table & beam saws, I use blade supports made from '60's era, thick-azz plywood blades cut/turned to dia. Makes the 0.060 safer & much stiffer. Have tried a number of steel cutting carbide blades; not impressed w/ life. I regrind old, thick, pos rake, carbide wood blades to a neutral rake & get 80% of the life out of a junk blade vs $35-45 for a new blade; takes 15 min to regrind one, if I do them in batches. Was just considering a diamond blade, last week, but will give the industry another yr or so to mature. As someone who's been dealing w/ cancer for 3+ yrs, the abrasive particulate in shop air is no joke. For you or co-workers. Who knows if the throat cancer I have was furthered from 50 yrs of grinding/cutting w/ abrasives. 1st 20-25 yrs lung protection was a joke; might as well tie a thick gym sock on yer melon, (new 1, of course!). But, if diamond can cut down on abrasive dust, it's a good thing. You do not want to deal w/ throat, lung, or any, cancer. At least wear a good, REAL respirator, not a paper cup. Diamond's the future...

I'm 57 years old and had a cutting wheel break apart on me for the first time a week ago. I'm lucky I had thick gloves on or my new nick name would have been 9 fingers. Finger is bruised all the way down to the middle of my hand and still hurts like a mofo. I'll be looking at these blades as an alternative.

I use the Lennox Blades and they work great. The link you provided (2 years ago) is not available any longer. Over time things go away or are no longer the focus of the manufacturer so they stop selling them. There are other brands beyond Lennox, but they haven't let me down yet, and I have 3 in reserve because the original is still not worn out.

Exploding abrasive cutting wheels have been mentioned several time in these comments, I gave those a Like. I always worry about the cutting wheels exploding. I'm just a hobbyists in my garage. With the info from this video I think I'm going to consider the daimond wheel. I would hate to ruin my weekend, or more, with a trip to the ER for a hobby. I appreciate this video

The general rule is to never never use diamond for cutting steel!!! The reason is diamond suffers very hard from the carbon in the steel with which it makes strong bonds during grinding and gets very quickly destroyed and dull. They must have put a very thick layer of diamonds to make it survive this long.

I'm new to all this. Would a Diablo blade be a better comparison to the OK Diamond blade? I would love to see a comparison.

The diamond wheels looks like it takes a Little while to cut metal but I'm looking for safety i don't want a fiber wheel breaking flying at my face or other people just caused i am in a hurry projects take time not speed ❤

Between both cutting wheels the abrasive is best kept at the shop, They are too fragile to take to the job and they wear down. The diamond slow leaves a big bur but can be banged around without much effects. A band saw is much better then both. Either abrasive wheel can work harden the material your cutting They both leave a bur they both throw sparks you can start a fire with either unit welding on a construction sight not something you would do with a bandsaw. Yes the metal gets warm but not that hot you cant pick it up after you cut it. Now if someone made a 4" grinder that had speed adjustment and a simple bandsaw type blade or even a wire you put around the part your going to cut that would be better. The wire would work like a saw in a granite mine the wire stays stright becuse its in a taught line that keeps it stright you either use oil or a coolent to cut.

Ya I have a Lenox Dimond blade that works fine for me as often as I use it and it's often in a bag and won't break like a regular cut off wheel and very little risk of it flying apart but the one annoying thing is when I got that blade like in clearance or something and on my cordless Milwaukee angle grinder it wouldn't tighten up enough the blade could still spin easily around the shank so I don't know if it was a problem with the blade or I got the angle grinder from a pawn shop so I didn't have it new but I got a big like 7/8 or 5/8 washer maybe I don't remember but then it's fine

Liked to see how it Cuts some 1/4”x 6” flat stock . Was it just me but did the Ok diamond seem like it was struggling on the 1”square.

I will have to buy one of these. Looks like they perform great.

Another thought: As the abrasive disk gets smaller the speed, (MPH), at the cutting edge of the blade slows down.

What are those table vise grips you used @3:18? Those r cool

drj westfield wisconsin what about black pipeline? Can you cut it down the center of the pipe?.

Could use an abrasive wheel on a chop saw all week can this wheel do that . That’s what u need to show longevity at the end is what matters one wheel does it all cuts grinds all without changing wheel great vid

Those ok Dimond looks a lot like the Lenox blades but they may not actually be making their own either

Diablo & Evaluation "cold & dry cut" carbine hands down ! the matter of which last longer is to be addressed ? The cold & dry cut carbide will cut rail-road track, I've witness this on KZfaq ! Will this sharpen carbine blade teeth such as stump grinder teeth etc. etc. being that it is a diamond blade ?

After 55 years of working with steel, stainless steel, aluminum and other metals. Friction saw , cut off wheels and diamond. May be handy to work with. They are more dangerous than plasma and oxygen: acetylene torch.. Saws are very good for square cuts and easier to clean. Friction Saws blades have a tendency to blow apart. Handheld can grab and bind .

Abrasive wheels have their advantages but they certainly aren’t the best way to cut metal stock, my band saw still cuts the majority of my stock as it leave’s nearly no cleanup of the stock before placement & I can walk away while it’s working..also no airborne dust & so much more quite .

Faster and cleaner cut from the abrasive

Looks like the abrasive disc cuts faster way more sparks vs diamond disc.

How does it work on aluminum?

Wish you would have demonstrates thin sheet metal for Us body workers

ok so heres what i have noticed, it takes longer to cut, it makes greater noise when cutting, it leaves a heavy bur that you will need to clean, and as you use it it dulls away making all the above much worse, second even if the abrezive wheal starts to shrink with proper techniq you can cut much larger object simply by twisting the object, and when you ar cutting thicker material it is always better to use a chopsaw with an abrezive or carbide blade, I prefer the carbide blades for my projects, they ar best suited as they cut fast enough clean with less noise and with less sparks, and i use the grinder only for small stuff, I dont need a bandsaw as my projects dont involve the need of a bandsaw, srry for my bad english its not my native language and it has been a lot of time since school

Abrasive wheel looks like it cut much faster and way cleaner. Also I have a bosh grinder with the x-lock which is muchmore convenient to use especially when welding you can switch from a wire wheel to a cuttoff or grinding disc in a few seconds without tools.Ill never own another grinder that requires tools again.

Can we cut wood from this diamond cutting disc? Is it safe ?

please put a link to where you can buy this cut off wheels, can't find them on Amazon

I would like to see OK compaired to Lenox or Diablo

Where can I get that sweet hat?

I've been using a blade exactly like this made by Lenox for about a year they are much better than abrasive cutting wheels

curious if you have any examples of linear cuts of 4' to 8' or using a fence compared to free hand. Thanks for sharing

Cutting steel with an abrasive wheel is faster, but you need to keep replacing the cutting discs. For cutting steel at a 45 degree angle, it is better to use a diamond cutting wheel, since that blade is more rigid and will not bend or break and will give a more accurate cut.

Maybe better than abrasive wheels but still behind cold cut saw & bandsaw.

The abrasive blade is the best.sorry,but the diamond wheel leaves rough edges and slower.we will stick with the abrasive wheels on our cutters thank you

The metal blades are ok for some stuff. They don't break when you throw them in your van and pile tools on top of them. Are they good for everything. Hell no, not by a long shot. I keep one for a backup though.

I don't see a point in using anything else than abrasive wheels for kutting metal. They're the fastest, they produce the least amount of tear on the material, and they cost pennies. Why spend 10-50x as much for a diamond wheel when you can do the same thing better, faster and cheaper? Diamonds are for tiles and other hard, brittle masonry.

I have thrown out every one of these metal/diamond blades that I have tried.....won't even try them again. The cleanup is more important than the cut. The diamond wheels melt the metal and don't remove the material. You will need to grind it away.....with a grinder.

Hmmm more material... Guessing the abrasive disk is wider ? Seems way faster too... Comparing sparks for something that cuts slower doesn't feel fair to me.

Diamond dust is the worst kind of dust to breath , look it up its no joke , never dry cut with these tools

Abrasive wheel is the better performer with less cleanup (dross), but the metal wheel is the safest and longer lasting with more cleanup.

I hate when the abrasive wheel breaks and becomes shrapnel. That’s the only reason I’d buy the OK diamond cut off wheel.

Diamond blades also cut through cast iron, concrete and stucco.

Where us the re-bar that tells the tail

A better alternative to a grinder for cutting metal-Both DeWalt and Milwaukee make carbide metal cut circular saws-faster smoother,cooler and NO sparks! Evolution Tools make metal cut miter saws that can cut BOTH wood and metal with the same blade.And with these saw machines no burring or burning-finish milled cuts.

I would have loved to see the comparison guys, but the tool sounds were left too loud to be watchable for headphone users.

I first want to see a bed frame test before I buy one....

When you say they asked you guys, you mean they waived a check at you

I tried 2 of them and don’t like them (don’t remember the brand). They are very noisy, produce lot of heat, don’t make clean cuts, bind up in aluminium and make a lot of dust. Two advantages : the diameter does not reduce, and they are vulnerable like normal cutting discs. The cons outweigh the pros.

even as a low level welder i know fiber is better for metal and diamond disk is probably made to cut bricks rock and stone

its a lot louder and slower than the classic wheels.

and a lot less smoke

The Diamond wheel has way less sparks that's a plus

Def alot less spark on the ok disc

he does more back and forth with the abrasive wheel this slows the cut🧐

Several observations in this video that I'm making. Yes there's more Sparks coming from the abrasive wheel because it's cutting over 30% faster. It's also leaving a considerably cleaner cut. It is a consumable however and the diamond wheel May last longer although you would have to do some long-term testing to determine that? Yes the temperature is approximately the same considering the cutting speed because you expend the same amount of energy to cut through the same piece of metal? No shit Sherlock, that's how physics work. I can't believe you made that statement!

Skipped ahead and stopped early but the OG is better. The new one doesn’t seem to be better in any useful ways. Every time I’ve had an issue with the cut off disk it was when using it improperly. Respect your tool’s ability to kill you and you are fine.

The abrasive disk is so much more cleaner Cut surprise you didn't mention that

Abrasive wheel wins at absolutely everything besides the safety issue, they are much cheaper too

why does this look identical to a masonry wheel?

4:33 if that's galvanized still you need to be out door's

Lot of damn cleaning to do
