I had my doubts if they would cut good for the price. I received the blades today and went out to my shop and tried them out. the first item I cut were some 12x12 carminic tile. The blade cut the tile like butter. I then tried cutting some 11/2 galvanized steel angle. It was a bit slower but still cut the metal. I think for the money they are well worth the price.

I’m a contractor and these are a must so cheap a never go dull. I bought 20 anyway as so cheap and best blade out there. So sharp.

I was wondering why an "indestructible" disc comes in a 10 pack. My first disk cut old galvanized water pipe pretty well. It made 8 cuts through half inch pipe before is was too dull to do much. That old pipe is tough stuff, so I can't complain.

I was taking down a chainlink fence and couldn't believe how fast regular cutoff discs would wear down and break off. Maybe I'm hard on them, but I tried these despite the fact that the "indestructible" disc comes in packs of 5 LOL. One disc so far has gotten me farther than 3 regular cutoffs and it's still going. So I'm satisfied.

These are great. Cuts everything, even marble. So glad I got it.

These are very dangerous. When I read the reviews I thought it was nonsense about them being so dangerous. What happens is that a part or chunk of the disk breaks off and then creates a gap in the disk. Then the disk gets caught in the metal you are cutting and rips the grinder out of your hand. I was fortunate that the grinder got caught in my pants shredding my pants and only leaving a minor wound to the inside of my leg.

When used as a cut-off wheel, the abrasives on the outer edge wear off quickly and do not sustain the quick initial cut speed. The thin edge that allows for grinding holds a little longer. It's still more durable than a standard masonry or steel cutting wheel. Kudos for not exploding under a stress test that would easily break another oxide-type wheel. It could be better, but it's still just a little better than a standard wheel but not quite worth the price over other wheels. Still happy to have some in the arsenal.

We bought these for cutting tile for a bathroom and kitchen. Worked great!
