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

Doing a master bath project and needed to sculpt the underlayment for the drain. This worked well and I had a lot of control with the 4.5" grinder. I also have a 7" version which works better for grinding concrete like sidewalks that have tilted and are trip hazards.

I needed to level a high spot on my walkway. Grinding was easy, but slow. A dust shroud is necessary.

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.

This, combined with a harbor freight dust collecting vacuum attachment, work surprisingly well to grind down some concrete high spots to lay down some new LVP flooring.

This is a good grinding wheel, comparable to the higher priced name brand wheels.

Good- quality is good, it fits without issues and gets the job done,Bad- very difficult to work with on a grinder

Very nice product. It is very durable. I ground about 200 sqft. of thin-set mortar that was beneath the tile I removed in the kitchen. It pulverized the thinset like it was cutting through whipped cream. This grinding wheel with a dust shroud attachment connected to a vacuum would get the job done like a charm.

We used this cutter to remove leftover thinset after hammering the bulk of the thinset off. While it was capable of the job, it removed thinset for about 6 sq ft before the wheel just polished the concrete. Because of the shallow cup to the wheel, I had to add shims to my universal dust shroud I added to my grinder.

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 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.

Hasta el momento ha funcionado muy bien.

Purchased this to remove leftover tile floor grout off a concrete floor. Couple tips that really help for removing the grout from a concrete floor. Lay a very wet towel over the grout for a couple hours so the moisture wicks through the grout and a bit of the cement floor. This keeps the dust way down, doesn't throw up water and cuts through the grout like butter. Much better than trying to grind when dry. Likely extends the life of the cutter as well. Just be careful as water and electrical tools don't mix, just don't crazy on the water, but most modern tools are double insulated.
