This wheel makes quick work of grinding thinset off concrete slabs, but practice in a non-conspicuous are to get the feel so you are comfortable you are not gouging the concrete. This wheel is perfect in conjunction with the 7" dustbuddie dustless hood which hooks to you grinder and shopvac...this is a must or you will be creating a white dust storm instantly. With the hood there is no dust at all. Don't try to get around it if you are indoors...spend the 99 dollars on the dustbuddie. Empty your vac about every 20 minutes and shake off filter to prevent filter blowout and keep good suction. Here's what I have into this system:Ridgid WD1670 16 Gallon Wet/Dry Vacuum - $180 (Great filter system)Hitachi 7" Disc Grinder- $99Dustless Technologies D1850 DustBuddie with 7-Inch Universal Adapter= $99.95DEWALT DW4775 7-inch Grinding Cup Wheel Double Row- $89You can go with the 4.5 inch grinder, but if you're going to do a lot of floor, go 7-inch.Hint: to be completely dustless, put tape over the adjustment holes in the top of the dustbuddie hood (where the sliding screws are). This diverts more suction to the underside of the hood and prevents escape.Good Luck.See all 1 customer reviews...
