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 break off easily.

I ordered these to use for cleaning the bore on brake caliper slide pins. Ive only used them twice and theyve worked perfectly both times. Makes the work so much easier.

Total junk. Within 5 minutes of use, removing paint, most brush bristles came off. New one for comparison. Would NOT buy again.

Very good tool

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!

I intended to us these brushes as a drill attachment to remove loose paint on some rusty cast iron railings. It took about 1 minute before the brush was virtually gone and the shaft cracked in half.

2 brushes broke within seconds of use.

Great value

Great that there is various sizes to choose from in the set!

Not as durable as I wouldve thought. Used them to clean dirt and grime from in between my intruments back crevices. Purchase came with 6 bits ended up with only 2 in the end. Didnt really get to use much of those 2 the others broke within minutes. Not made for small crevices even the smaller bits.
