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

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

This is a good product for scuffing up or sanding. you have to spin it at its recommended speed or slower or it melts away quickly and will transfer the plastic to the surface. its a very aggressive and hard to control sanding action, any highspots were stripped off quickly. it has a lot of torque as it flattens out to 8 inches when you spin it. You dont want it to be flat. The slower it turns the better it sands. The brush fits into the corners and curves well and you bear down on a little to fit into dents. Use safety gear / a good dust mask and sand outside - it makes dust. Used yard blower to remove most of dust. I used a Harbor Freight $20 angle grinder which is not the correct tool and toggled the power switch to spin slowly. This put stress on HF angle grinder and and it was OOC after doing the bed scuff and 6 dents that needed to be done . I accomplished stuffing the pickup bed truck in about 1 hr. Using the wrong power tool to run it It was well worth it. Still have 3/4 of brush left. I was prepping bed for DIY $100 herculiner coating; due to unseasonable exceptionally freezing cold weather= I could not keep my garage at a stable temperature. Bed was sprayed with base Line-X. My friend is happy because were doing his truck with free DIY coating and hell supply refreshing drinks.

Good for sanding the back of pick ups for bedliner prep. The reason for four stars is the cups is s little hard to navigate opposed to the smaller 4 inch heads but the six inch head does cut faster.

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!

very aggressive very strong bristles.

These nylon brushes are great! Very forgiving for unexperienced users!

great tool

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.

Doesnt come with a drill bit to attach to drill. Had to make one out of a 5/8 Bolt, but doesnt pull up paint whatsoever. Had to go with a dependable wire brush drill attachment. Worked 1000x better. This product is garbage, and you should be ashamed for selling it.

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.
