I am glad I didn't spend the money on the for the brand name grinding wheel that was about 2X more expensive. I used this tool to grind off the linoleum glue on the surface of my basement floor.

Worked perfect and lasted much longer than I anticipated!

Great product able to specifically grind concrete floor at the exact level needed

Excellent performance, better than most of the other expensive products!

great price, cuts cement quickly

It's moderately priced for such an accessory, but performs well.

Good werkmaster diamonds, very cheap prices.

Very effective little grinding head - did a great job in concrete floor, cut fast.

Excellent polishing disc for concrete.
