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

One broke so not very sturdy cheap metal

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.

Pretty much breaks with any amount of pressure applied. Almost all of them broke

First brush I tried was kaput in a minute...bristles all wound around wire....not good.

There was supposed to be 6 brushes, only received 3. Package looked like it had been opened/tampered with. Would have returned and requested refund but wasnt worth the aggravation and time.

I needed to clean out some rust on a few threaded holes. These bore brushes did a great job of getting the rust out but after some vigorous use there was some breakage on the bristles. No complaints on the value because the rust in the threaded holes was 7 years old but that did drop the durability score to 4 stars.

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

Very good tool

Not suitable for heavy cleaning. Brushes collapse to shaft and the shaft breaks on the smaller sizes. Light duty only.
