Answer: 
Works great with water. I suggest working small areas and stand a few 2x6 blocks around the area you are working to contain the wet muddy spray. This worked great for me and made cleanup a lot easier

Answer: 
Yes. Wet is the best way. You have to keep wetting it though, once you grind through the wet layer, it's dry underneath. Keep a small bucket of water handy. Be prepared for a mess.

Answer: 
The RPM rating doesn't have a minimum, because the slower you go, the less stress you put on it. However, if you're going very slow (say, sub 5,000 RPMs), your work is going to take a LOT longer. It worked well for me at 12,000 RPMs. I'd say you want to be at 10,000+ for best results. This attachment is designed to take a little bit off at a time, but at a very high rate.

There is not a minimum RPM, it really depends on the machine being used. But for safety purposes, product is rated for max RPM 13,000.

CUSTOMER REVIEWS

Rated 4.7 out of 5 by 47 reviewers.
Rated 5.0 out of 5.0 by Works great. Don't be a fool like me I bought this and was using it with my milwaukee angle grinder. I was moderately impressed initially. It was grinding at a pretty slow rate, and making a HUGE mess - both when used wet and dry. After hours of this I called it quits. A week or so later, I decided I was not happy with the results and needed to grind more. I purchased a dust collector attachment for my angle grinder online, and went back at it. Wow, the difference that made was incredible. Not only is there very minimal dust escaping into the basement, it cuts atleast 10 times faster. This is the only way to do it. April 29, 2016
Rated 5.0 out of 5.0 by Excellent Did a great job cutting through my cement countertop... tried to add a pic but after 5 tries of resizing... I gave up! May 17, 2016
Rated 5.0 out of 5.0 by Did the job. I removed vinyl tiles from a basement floor and found a very thick layer of black mastic on a cold uneven concrete floor. The diamond cup wheel took the mastic off and I was able to take the high spots off the concrete. April 26, 2016
Rated 4.0 out of 5.0 by Rigid Grinding Wheel A little pricey but worth it. Able to grind about 100 sq. ft. of old tile thin-set off of a concrete floor in about 6 hours. March 15, 2016
Rated 5.0 out of 5.0 by Great Performance Bought one of these to level a toilet drain entry to a concrete floor. Couldn't have done the project without it. Ran smooth, cuts like a devil, and filled my exact need. I leveled about 2 square feet and the tool looks to be unused. As noted in other reviews, it makes a ton of dust, but if you do this BEFORE you do the rest you can use water to keep things clean. My bathroom project came out nice, and this tool made it functional. I recommend this piece. March 6, 2016
Rated 5.0 out of 5.0 by Great Concrete Tool! The 4 in. Double Row Diamond Cup Wheel preformed very well on my grinder and area I needed smoothed out was completed in no time at all. It is hard to tell if the cup wheel was used up in any significant amount. Definitely well worth the price and the quality of the tool is top of the line. One will last a very long time. February 10, 2016
Rated 5.0 out of 5.0 by WORKS AMAZING I used this to removed tile grout from concrete. This wheel is amazing. It works so quickly. If working with concrete or grout, be aware of the dust that will be created from grinding. January 12, 2016
Rated 5.0 out of 5.0 by Worked great I used this wheel for the first grind of my concrete counter tops. I used a disposable pad for the first top and it took forever. So a ran to HomeDepot and picked up this wheel and it sped up my process 100 fold. I blazed through the rest of the pieces. October 28, 2014
