7" Diamond Grinding Wheels for Concrete or Masonry, 12 Turbo Segments, #30/40 Grit, Medium Bond, 7/8"-5/8" Arbor

It worked very well for my small project to grind down uneven concrete floor in prep for a new floor covering. It cut the concrete ridge down in little time and left the surface with a nice smooth finish. The tool appears to have plenty of cutting time left on it.

I bought this for use in my EDCO edger to remove 2 coats of epoxy paint from a concrete floor. I have used it to grind 1500 square feet and it has finally worn out. Leaves a smooth finish and has outlasted my expectations. Well worth the price.

The only reason I didnt give it a five star was that i had to use an adapter nut to install it on my Dewalt grinder instead of just spinning it on the shaft!

Great

Lasted quite a while. Did what it was supposed to do. Don’t force it. Let it do the work.

After taking up 130 sq. ft. of ceramic tile I used this wheel on my metabo grinder to remove the thinset that had held the tile down. It was very effective. I would strongly encourage anyone to use a grinder with a dust shroud and a good vacuum.

Bushing would not stayed in wheel no matter how much I tightened the grinder nut. Don’t waste your money!

This cup was used on a Hum-B Edge floor grinder that has a Dewalt D28494 6,000 rpm 5.3 HP Angle Grinder. This unit has gas-filled shocks so any vibration is eliminated -- some users reported vibration. The 12 heads produce a fine smooth finish.

Great product
