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

They worked well!

I use the brushes to clean bushings.

Well this is my very first total disappointment review on Amazon. The product didnt hold up. First time I ran this down a bore in an aluminum tube it fell apart. The bore was ever so slightly smaller in diameter than the brush used. hardly any interference fit at all. Ran it up and down the bore and stainless steel wires started falling out. Bummer because there were a good fit for my project. Oh well. Ill return them and try another brand.

Absolute junk. Broke within two minutes. Do not buy.

I use them to clean out the piston holes on brake calipers of seriously clogged brakes.

Broke of as soon as I tried to use them. Coat hangers are made of stronger wire. DO NOT BUY!

Excellent

Consider each brush one time use but did its job brushing rust off in a tight spot.

Two of these broke within 10 seconds of starting to use them. The next two were shockingly too big or too small. Dont waste your time on this product.

Ive been cleaning up some vintage tools and bought these to get to the inside of sockets. The various sizes worked well for the different sizes of sockets and the brushes seem to wear well so far. Ive found other uses for the brushes as well, such as cleaning other tools, detailing parts of my car and cleaning the nooks and crannies of my grandsons toys. Still in search of a very small brush for cleaning usb 3 contacts and other really small items, but these have been great for what I bought them for.
