3 Pieces 4 Inch Concrete Stone Ceramic Turbo Diamond Grinding Cup Wheel,12 Segs Heavy Duty Angle Grinder Wheels for Angle Grinder (Yellow)

Been using this on fieldstone for a month. Holds up great. Just as good as the more expensive versions. Great value.

I needed to shave down some concrete for the entryway of my driveway and this did the trick wonderfully. I use a 4-inch angle grinder by Makita and had no issues. Item comes with a washer in order to adapt to the smaller arbor.

worked great to level out some bumps on bluestone under a pair of stair stringers. i was worried about going with the ultra-cheap wheels on amazon but it worked great. for the small project I had. With two concrete grinding wheel for <$10 one obviously would expect the world. But worked great for my small project and the wheel I used looks like it could handle a couple more small project.

It does the job but not high quality, poor finish.

The blade fit my older Makita 4” angle grinder. Worked fine though we had more cement to remove than anticipated. Ended up buying a larger angle grinder but these blades are a great value for the price.

Works great.

Works great. Remember to buy a dust shroud if you’re grinding indoors. This works so well you will fill a 1000sq ft with dust in 10 minutes if you don’t......I did. Ugh.

This grinding cup is well worth the money. Ive used on stone, brick and concrete and its never failed. Works as well as cups 3x the $$. This size is easy to control with one hand and great for working single pieces and small areas.

Works great grinding concrete garage floor.
