I paid 14 dollars for these and 1 cup did my whole truck frame. Ran good on my metabo angle grinder that is 10k rpm. I will definitely buy these again but it will probably be awhile since they last.

These twisted cup brushes work great on my angle grinder for cleaning rust off surfaces. They screw right onto the arbor after taking the retaining nut off. You don't use the retaining nut to hold them on, you tighten it down with a wrench like you would the nut.So, because of this, it may or may not fit your angle grinder. It depends on the thread size of your arbor. These fit fine onto my 4.5 inch corded grinder, but they are too big for my 4.5 inch cordless grinder, so make sure you have a 5/8th inch x 11 threads per inch (5/8" - 11) arbor before buying.

These twisted cup brushes work well for removing rust, corrosion or even heavy paint from metal surfaces. They easily screw onto the arbor after removing the retaining nut, and you secure them with a wrench instead of using the nut itself. The knotted wire brushes are much more durable and throw stray wire less than the non-knotted, so I tend to use them more. They last a really long time, and the price is a good one. I'd get them again.

Review of RealPlus Coarse Crimped Wire Cup Brush for Angle Grinders: This worked well for removing rust and old paint from some cast-iron pieces. I'd avoid using these on aluminum if you don't want to end up with a brushed-metal look. Definitely a lot quicker than my previous experience with wire wheels in an electric drill.
