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

EXCELLENT 100%

Will not fully remove all rust, but cleans quickly. Doubt Ill ever wear it out, used for 2 hours and looked like new.

showed up on time works great to prep corners and hard to acess areas

hesitation on acceleration between gears disappeared! very good, product, good performance. priced great too!

Last long enough cleaned about 200 sq feet of barn wood b4 it was used up with no wires

works well to rough up a painted surface without ripping down to bare metal. Purchased to rough up truck bed before spraying on bed liner

Works great on my angle grinder, more abrasive though than I thought. I was expecting something I could knock rust off without leaving swirl marks in the metal but oh yeah it does. Since then Ive used it for various other projects and still like new.

Did not remove surface grout and left a red stain on the tile.

This thing is awesome! First used it to scuff my truck bed before spraying in a liner. Since then I have used it for a lot of projects from cleaning aluminum to removing adhesive from a deck hatch. Tough enough to clean what you need but soft enough to not destroy what your working on. Very durable also.

So I had a big job to do with this brush and I ignored the instructions and put this on my grinder at 10k RPM. Theres a reason these are rated at 2500 RPM max. When you run it at 10 K the bristles open up flat and you can pretty much sense the impending doom at that point. Im a redneck that prefers to learn the best lessons the hard way and I figured it would make a great story for the emergency room so I continued on anyway. I did at least use eye protection and was able to strip the inside of my truck bed for a DIY bedliner in record time but all the while fully expected the thing to self destruct and likely remove a permanent part of me with it. I got lucky and finished without incident but am convinced it was pure luck. Believe me.... if I think its stupid and dangerous, DONT DO IT!
