6 Cup Brush, Nylon Filament, 5/8-11 Thread, 2500 max.RPM

Works as intended

First, this is actually about 4.5 in diameter which, for me, is better. I put this on a slow speed angle grinder and used it to clean a slate bathroom floor and a travertine and slate shower in about 15 minutes. The mineral deposits disappeared along with ten years of accumulated soap residue. After re-sealing the shower the floor looked like new. Had similar results in the kitchen. Dont clean grout without one. My angle grinder was running at 2,200 rpm. Id go a little slower if I could.

Used a few times to prep for bedliner. Works great.

Used to scuff up a pickup bed before applying bed liner. Worked awesome and saved tons of time.

Used to clean a heavily trafficked, light colored, small stone shower floor. Built up staining that normal products like soft scrub or bartenders cleaner wouldn’t touch. Installed on my 5” grinder and set to lowest speed. Medium light back and forth passes. Cleaned immediately! No wear or damage to cup brush! Dave’s hours of scrubbing labor that may not have succeeded anyway! Caution, use slowest speed available and allow grinder some rest so as not to overheat motor! Great product!

Rocks? You just need a low speed angle grinder/buffer so you dont eat bristles. Looking to skuff truck/Jeep/topper/tub/boat for bedliner prepping? Then Buy this guy, the bulk of the brush in concert with your rotary tool is the only limiting factor, but itlol get you 95% on a Jeep tub in 95% less time. Then its onto the red scotch bright or sand pads for the rest.

Ive used these before. they are far better than a typical wire wheel.

worked well on my truck

Bought to use to scuff my truck bed for spray on liner, haven’t used but look good

Perfect tool for the job, if your prepping a bed for a spray in liner you need one of these to prep the bed.
