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

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.

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

This awesome for grout,tough floor stains and so much ore.

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

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

I used this brush to remove dry carpet glue from aluminum boat. Worked better then a wire cup without gouging or smearing aluminum. They do wear out so if the project is large 2 might be necessary. Wish I would have found this brush sooner. Recommend

I purchased this to use on wood to remove old finishes, although it did do that pretty well, it would have been better if it contained some engrained abrasives to help with the job. For the price it will work and has held up fairly well during this testing. I do understand this is not what it was advertised as the primary use, so I am not disappointed with the product.

I used it to clean brass drains grates and it worked fine. Problems is I use a 9500 rpm grinder to run it. The bristle fanned our and it over heated the tool. So, it works but don’t go over 2500 rpms

Great product. Good value.

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