Got pretty good grinding out of this disc was grinding badly finished sidewalk to expose gravel. Should have bought two because it lost a bit of it's power fairly quickly but got better performance out of this only disc compare to 3 other store bought discs I also used for the job. Fitted perfectly my Dewalt 5 inch grinder with amazon dust shield. Would by again. No shaking and not alot of marks when used level.

This diamond coated wheel is Very sharp - be careful handling it. The thin edge cuts right through concrete, and with the flat edge you can shape concrete. Happy with my purchase; I'd buy this Concrete Diamond Grinding Cup Wheel 4-1/2" again.

Surprised how well this did the job. Needed to cut a grove for improving drainage. Did the job easily.

I wasn’t sure how many square feet I’d be able to grind to prep my floor for epoxy coating. I managed to get about 400 square feet but it was pretty much done by the end. Accomplished what I needed.

1/3 wear-out for first time used, but for a weekend job. They are perfect! Don’t forget it just cost below $30, what do u expect. I have no problem with it!

I used this grinding head on a 9" Makita floor grinder. It did an outstanding job with little wear.
