BOSCH DC530H 5-Inch Diameter Turbo Row Diamond Cup Wheel with 5/8-11 Hub

wears too quickly

What's to say? Nothing lasts as long as Bosch tools. I used to pick these up at Home Depot near my house but they don't carry Bosch anymore. Besides, I got a better deal here at Amazon! With a little care and a variable speed grinder you can get a fairly smooth finish. I cleaned over 200 sq ft of brick surface and took 1/16" off about 80sf of concrete floor and its got plenty of grind left in it.

They are 4 1/2", not 5." I put it on a bosh floor grinder and the disc sits below the dust shroud. Had to cut some of the threads off with a metal saw to get it flush to the dust shroud.

This grinding wheel has worked great. I poured the top of a retaining wall and wanted to expose the aggregate and have it look more like stone then concrete. So far I have ground more than a hundred square feet and it is ready to do some more.

Great item at a great price

I accidentally ordered the wrong part to work with the Bosch vacuum attachment. If you want to use the vacuum attachment (Bosch 18SG-5E) order this with the 7/8" arbor; otherwise, it will stick out too far and the vacuum attachment will capture almost nothing. Basically if the model # has an H on the end you've got the wrong one. I was able to make it work by extending the vacuum attachment with tape. Aside from my ordering mistake it worked very well for levelling a concrete bathroom floor.
