3Pcs 4'' x 5/8'' Nylon Filament Wheels Cup Brush Set for Angle Grinder ,Include Grit 80 120 240 ,Nylon Drill Brush Kit for Removal Rust Corrosion Paint (3Pcs Set)

these will fit on an angle grinder, and they do work, but not having a threaded nut, they are very hard to remove. the standard wrench that comes with a grinder will not get them off as you can't get them down inside the cup far enough. had to modify a wrench with longer pins to get them off. not worth the trouble. update: don't worry about getting them off, after about 20 minutes of sanding house paint there is not much left of them

It didn't last even five minutes. Just the speed the of the grinder fanned out the bristles and made lots of them break. The rest broke off as soon as i started to use it to clean a surface.It would work grate if you had a lower speed or variable speed grander.

They are not what was described in the listing a 4 inch nylon cup brush, it is in fact a very good 3 inch nylon cup brush set, removed corrosion & rust w/o damaging adjacent surfaces.

I haven't used these yet but they look sturdy. These came as a set of 3 different coursenesses. That's why I bought them. The only thing is that they don't have a threaded hole to attach to a power tool. But no problem, I have a way to adapt & use.

Didn’t hold up very wellPieces kept flying off during use

These are great little sanding wheels.

Use these brushes for doing woodworking projects. Must use slow speeds while using them as that is what they were made for.

Used for metal refinishing.
