6 Pieces Stainless Steel Bore Brush in Different Sizes Twisted Wire Stainless Steel Cleaning Brush with Handle 1/4 Inch Hex Shank for Power Drill Impact Driver, 4 Inch in Length

good deal and prompt,well worth the money, thanks

Didn’t last at all. Returned them after one broke on the first use. Stay far away.

The first brush broke after 10 seconds of light use. The bristles on the others wore down in less than a minute of use. Dont waste your money!

Good stuff

I received yesterday and used the 19mm brush to clean light rust from some 3/4-10 internal threads. The brush came apart within less than a minute of use. I had high hopes for these brushes. Very disappointed.

I bought these because Ive always dreamed of a brush that i could put in my drill and make quick and thorough work of cleaning up the inner surface of my automotive battery terminals. All it takes is a zip, zip and its good as new.

These are alright. Once you use them a couple of times the bristles get matted down which makes them more difficult to use. I broke one as well. They bend easily as well so if you’re not trying to do any tough work these are fine. If you do something that requires some force these are not for you

Taking out rust on interior pipe threads

NA

Attempted to use on hard to get places on a rust removal project. Cant apply any pressure at all against them. Broke 2 within probably less than 5 minutes of use.
