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.

Rated 4 out of 5 by from Good product but expensive Used this for a large exterior cinder block building. We used them to in lieu of scarping the loose paint and broken down mortar. Total of about 15,000 ft sq of surface area. Went through a lot of them. It was worth is but the dewalt ones from lowes are 4$ cheaper and last much longer

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