Diamond Grinding Cup Wheel 5 inch for Angle Grinder, Polishing and Cleaning Concrete, Granite, Stone, Marble, Cement, Masonry, Rock

I used this to grind down refractory concrete on the forge I was building and it worked perfectly fine with an angle grinder. I bought it thinking that it would be a one time use which is fine in my case. But it held up fine and did a very good job. Compared with the high prices of the competition and with me only planning to use it one time, this worked very well.

This was THE most worthwhile tool I’ve ever purchased. It’s messy (Used fans)but got the grout off for new flooring. I jack hammered 1 whole day before finding this grinding wheel. Stayed sharp !

This did the job I needed it for. It wore down faster than anticipated. The center fixing nut eventually came in contact with the surface being worked. I added a spacer under the wheel to keep using it squarely. I was really happy with the finish it produced.

Female who has never used an angle grinder and intimidated by it. Had 25 18x18 tiles with dried mortar over 2 yrs old. Removed it easily. Given the amount of mortar removed blade already shows sign of wear which is expected. No sparks flyin not intimidated any more!

Durable for granite.

I thought that because it was cheap that it might not work as well or last that long, but it still has a lot of life left in it and worked great.

cut through like sanding wood

I lost the money, he did not do the job, very por quality.
