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

Within the first revolution the bristles were flat against shaft. They were useless

Very small in size not practical to use

Bought these to clean out the hex head openings on the alignment cam adjustments for semi trucks.

They were as advertised. Did they work? Yes. I used up 4. Each one cleaned out one slide bolt hole on a brake caliper bracket shredding in the process.

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.

just what was needed to work on a pressure pump

Did what I needed but they were a once and done piece.

Wear out and bend very quickly

3 brushes broke in 2 minutes. Complete garbage.
