KSEIBI644030 Diamond Concrete Grinding Wheel 4 1/2 inch for Polishing and Cleaning Stone Concrete Surface, Cement, Marble, Rock, Granite, and Thinset Removing, Angle Grinder Wheels Cup

I used this wheel with a 5" Bosch grinder to dress a large piece of granite in preparation for mounting street numbers to the stone. The wheel performed very well on this task. When I hit a soft spot on the face of the stone, some of the material sloughed off, requiring me to remove more stone then I planned. The wheel made this task easy, taking aggressive cuts where I need them, blending in the tool marks, and then feathering out the edges of the cut to blend the edges into the surrounding surface. The flat area was a perfect mounting surface for the iron street numbers, and the wheel still has a lot of life left in it for the next job. I could've paid twice as much for a comparable name brand wheel (which was also made in China), but this one did everything I required of it.

Used it more than a hundred times. Perfect everytime. Does a great job grinding.

Cumplió con su función, la verdad es que no sé cuánta es la durabilidad por que yo solo lo usé en un pequeño espacio, quite exceso de cemento que tenía en el piso para poner mi loseta, es muy rápido así.

I used this cup grinder to take down high spots in my old cracked driveway prior to filling cracks and painting. Worked extremely well. Cut very fast. Price was great.

I used the grinding wheel to remove flaking paint from concrete. It cut through the paint and scuffed the concrete. It only needs mild pressure otherwise the wheel will cut into the concrete. It prepped the surface well as i am going to tile over the concrete.
