4 Inch Concrete Grinding Wheel, 6Pcs Concrete Turbo Diamond Grinding Cup Wheels for Concrete Granite Marble Masonry Stone, 12 Segs Heavy Duty Angle Grinder Wheels

This is good blade, it last long

Ive never cut concrete with a grinding wheel before so really was shooting in the dark so I did not get the name brand high dollar wheels because like I said I really did not know what I was doing, lol, so I got the grinding wheels that were a little cheaper but not the cheapest, arrived and I went out to just tinker and see how it was going to work and how fast it was going to cut down the ledge, WOW, very surprised (again not knowing what I was doing so that might be normal) I was very happy with my purchase

These grind like butter! Needed to get some epoxy paint off the carport surface to build a footer. Worked like a charm. Decided to grind into the concrete a bit to get good adhesion to the block being layed. One pad lasts awhile, happy with the product

The arbor on the disc is at a bad angle and depth and they do not lock to the grinder safely.

Used to grind tile thunder. Stone last for a small room. Get a couple as backup. Fit my harbor freight grinder.

I always end up losing the little spacer that makes it work with my grinder
