Great grinding disc, I needed to grind down a cement bench that I made and it worked wonderfully! If you don’t have them, be sure to buy some safety glasses or goggles!

Used this with cordless dewalt grinder to grind high spots on a cement slab. Worked really fast. Definitely wear safety goggles because the grinder spits little pieces everywhere.

Great for soft to medium hard concrete to prep for coatings. Lasts a long time.

I've been trying various diamond attachments for my angle grinder to smooth out the inside face of the door for my glass furnace. There gets to be some buildup of whatever glass and refractory get together to form over time, which has been impervious to anything else I've tried. This one, though, goes right through it - it was exciting to watch! It's pretty amazing.

I wasn't sure if this was going to work well but it did. I grinded down a crack in concrete that was at least 1/2in high on one side. It ate right through it. just make sure you get the cover with the shop-vac attachment. It will throw dust everywhere!

I bought this accessory to grind down some thinset left on a concrete floor after removing some tile. I also needed to grind down some concrete where I squared off a curved corner of a sunken shower.This thing worked great! Almost too good!!I used the dust shroud & a shop vac to keep the dust down, but still had a cloud of dust.Highly recommend a two-cartridge respirator for this; not a paper dust mask. Also, wear goggles.

The best grinding disk out there

This grinding wheel worked like a charm to grind away 60 years worth of crap on our 100-year old house basement walls. Paint and plaster they used to fill in holes (who does that on concrete?) didn't stand a chance. Will buy again when it is worn away. I used it on a dewalt 12 amp grinder with the dewalt 5" vacuum shroud. Do not think you don't need face protection or good mask filtration with this set-up. Stuff really flies when you get going and dust still gets released.
