Bore Brush Bronze Bore Brush Bore Cleaning Brush Set Wire Bore Brush Set Stainless Steel Cleaning Brush for Power Drill Impact Driver (Stainless Steel, Brass, 12 Pieces)

Not the longest service life for what I was using them for (cleaning up the edges of wood slabs) but they do what they're supposed to do and the construction is pretty decent. Tools were "on-center" and I didn't have any weird wobble or off-center performance in the pieces I got.

I bought this mainly to work on cars, and have used them to clean battery terminals, brake calipers, and various other parts. They seem to be holding up fine, at least as well as expected.

Received product on promised date. Intended to use brushes for removing old paint situated in small openings in cast aluminum picnic table I'm refurbishing. This application is not what brushes are designed for and they did not work as hoped. The brush wire quickly became compressed and wrapped around center post and then broke off during use. This is my error, as my application was probably not a appropriate bore-type one and way too heavy duty for this style of brush. So, I advise lighter duty use for these brushes, which they should great for.

I used these to clean between the fins on my shovelhead. They work fine until I went a little too deeply. As soon as I did the tool broke. Whatever material is used to mount the bristles is weak. It's probably not aluminum but it looks and responds like aluminum.Used gently these are fine but in tight places they break pretty easily. A bottle brush you can mount in a drill or an impact gun is a nice idea but I won't buy this set again. It's just not built tough enough to do the work I need it do.

I put these little brushes into my drill and used them to clean out the holes of a badly rusted brake caliper. They worked best with a little oil and removed the rust and rough patches.

Works great for the price.

I was looking for something to clean copper pipes and this did the trick.
