Customer Questions & Answers

Will it prep wood for paint?

Asked by: Rex
Yes but it might dig in the wood. It's pretty powerful sanding action designed for steel.

Can this be used on a Drill?

I am looking to clear out the end of a 4" drain pipe that has some ice build-up. Ideally, i would like this mounted on a 12-16" shaft in order to get up the pipe a bit. Currently, I use a 16' paddle bit to chip away at the ice but this has been putting some good size knicks in the pipe.. Thanks for any input!
Asked by: MusicJock
No, not as it is out of the package. You must have a grinder or you may be able to buy a mandrel adapter for the drill.

This purchase was to replace a brush knot cup utilized in a grinding project, which the cup handled quickly and with no issues. The twist or knot of each set of wires makes this cup more aggressive then a straight wire cup (those wires are not twisted but extend straight down from the cup) so a choice can be made depending on the application of the grinding project. Please wear, at a minimum, a good quality dust mask and preferably a half-face filter mask with one or two cartridges to insure no breathing problems are encountered during and after the grinding project. Eye protection is a must as the occasional small wire is discharged from the cup while grinding.

I had 4 steel wheels to do, 2 of which were so scaled and rusted from being under the truck and holding salt etc. thought they would never come clean. The brush with separate adapter needed to fit 4" grinder worked fantastic. After plenty of time on 4 rims, then battery box in a Kubota tractor, then snow blower housing hardly any wear at all. GREAT but being small the seller should know it will be used on a 4" grinder as such come with adapter sold separately.

It's small enough to get into most corners, yet big enough to clean up larger areas without taking hours. Be sure to remember your safety glasses or face shield, and a jacket/apron as an occasional wire may fly off. Twisted wire style lasts much longer than the usual cup brush with straight wires. If your grinder or drill has a handle, use it for safety and control.

Extremely easy to install and remove from grinder. This wire brush did a fantastic job of prepping for the finishing brush and paint. I highly recommend this if you have a metal surface to prepare for painting.

Easily removes old material and can dig down if necessary. Only question is how long it will last but so far wear is minimal.
