Anyone use the diamond edge cutting wheels?

crane operator · Dec 19, 2020

At a jobsite the other day and they had one of these in a 4 1/2" angle grinder. They said they work great cutting welds off, and last and last.

Just wondering if anyone else has any experience with them. I'm going to order a few and give them a whirl. Can't be any worse than the regular cutting wheels, they seem like they don't last at all anymore.

I have used diamond wheels on my gas ax mainly for concrete ,but they would go through rebar no problem. We always went back to abrasives for straight steel cutting ,the diamond wheel was too costly to waste.Maybe these new ones for angle grinders are purpose made for misc steel cutting. I use zip discs a lot especially for cutting cable around the cranes ,i keep a Millwakee cordles grinder in the truck allways now . It beats the hell out of using guillotines to cut cable . Ill be looking for one of these diamond wheels to try ,it would be great to get 1000 cuts on 7/8" cable.

If u have any vendors that drop by your business that refill your bolt bins & such.. they will GIVE U SOME to try out..
I know Kimble Midwest does that..
That might save u a few bucks.??

Tried the lenox ones hated it cuts slow and loud way to expensive the only advantage is they dont crack when handled rough The abrasive wheels have to be of good name brand I havent found a faster cutting longer lasting wheel than the 3M Cubitron II we set up a test with the diamond vs 3m on a 1 inch bolt the abrasive wheel was twice as fast
I usually get them in 6 inch it sounds funny but the 3m wheels dont smell as bad as cheap ones when your cutting (;

I was very disappointed lenox cut off disk. It burned more than it cut. Lenox sawzall blades are the best bur that disk sucks

They do cut a lot slower but seem too last a long time.
I’ve tried a few abrasive disc that would disintegrate in the first use. Should be labeled as very dangerous. I will only buy Walter discs now until someone shows me a better one that I can purchase locally.

I tryed the lenox 4 1/2 it was slower i will keep one around but will not use it all the time. I have heard that a old diamond blade for gas ax was good for cutting aluminum scrap i want to try it and have saved some but havent try it yet.

Have any of you that have tried this disk used a water cooling stream while cutting with it? Most of my diamond wheels that I use to sharpen machine tools require some water to work effectively. I've used diamond type wheels in the past, especially on carbides, and they are slow but do work. I'm thinking a water stream onto the wheel would keep it cooler and wash away debris faster for the fastest cuts possible with this type of abrasive.

I think it won't work very well for cable, I can see cable getting snagged up in the relief slots in the diamond cut wheel. The wire strands kind of spring around as you cut them. But I could be wrong.

I never cut cable with a guillotine, I always use cut off wheels, and put a hose clamp on each side of the cut, and hold it with a vise grip so it doesn't unravel. I'd hate to cut 7/8" -1" with a cutter.

Tugger2 · Dec 21, 2020

They work ok as long as you have them on something real solid and make sure the knife is in the cut before you hit again. But they seize up ,guys bust the knives and they can shoot wicked chunks of cable. My millwauke cordless with zip disc works like a hot dam , i use quick knobs on the buckets ,you need to cut em off flush to get the wedges out.

I'm glad you haven't CO !
I punctured an eye using one many years ago. A chip came off the peg when I hit it with a sledge hammer. Dum ass didn't have safety glasses on. No vision loss, but I have a scar 1 mm from the cornea in my left eye.
A warning to all who read this.

I tried one on a 4 1/2 inch grinder, I didn't like it. Seemed to generate a lot of heat and was very noisy. It also bounced a lot when trying to start a cut. I continue to use the grit type wheels for the most part and have learned how to use them without burning them up so fast. I switched to carbide blade in the chop saw with good results and have a carbide blade for the grinder as well. You have to be real careful with it in the grinder, it's not forgiving. I use it mostly for aluminum in the grinder.

I'm not a fan the chunks coming off them are terrible like getting sandblasted if you accidentally aim at your self

Steve Frazier · Dec 22, 2020

By the way, I think it lasted about as long as 6 or 7 of the grit style discs

Long sleeves and gloves are a necessity.

I have been using one on my 4-1/2" grinder for some time now. It seems to work alright for bolts, etc. I would not try to cut a 1/4" by 2" strap with it. It really cuts plexi-glass clean with little smell. That's the main reason I bought it. It was not spendy, under 20 bucks on sale at ACME tools.

Tim.pin · Dec 25, 2020

I used it and they seemed to last a long time to me. I do wonder why is their edge divided into several equal parts. That always kept me wondering. Does anyone have any ideas?

Jimothy · May 10, 2022

We have used a bunch of these ,usually only worth it on lighter materials have to get thinner style if you can, yes the thicker blades last longer but will slow down the cut. The owner will be happy because he is saving money on blades. The foreman will throw it into the nearest dumpster, forest, lake or just straight up smash it. Time is worth more then Money
