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

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!

USED THIS TO CLEAN A SHOWER BASIN IN A CONDO PURCHASE. WAS VERY STAINED AND USED MILD ABRASIVE CLEANER WITH THE BRUSH ATTACHED TO A BATTERY DEWALT ANGLE GRINDER. RUNS A LITTLE SLOWER THAN A CORDED GRINDER WHICH IS WHAT I WANTED. TOOK LESS THAN 5 MINUTES TO HAVE IT POLISHED TO ORIGINAL.

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

Was searching for nylon abrasive brush didnt realize till I was looking at the package that it doesnt say abrasive anywhere. Tried it and sure enough, it will clean well but it isnt abrasive.

works well and holds up well

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.

Bought to scuff my truck bed before applying Raptor liner. Worked very well on a rotary buffer. Do NOT use on a grinder. It spins way too fast and will damage the brush or the surface you’re trying to scuff. A variable speed buffer from Harbor Freight works perfect. Would buy again!

very aggressive very strong bristles.

Th cup brush itself is great, But I wouldnt bother with it unless you have a variable speed grinder.
