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

Theyre okay. They do the job but mine didnt really seem to last. The brush stem would bend pretty quick in my use

NA

Wire brushes fell off after one use, wire shafts broke

Good stuff

I used 5 of the 6 brushes to clean gaps in an old radiator. In less than a minute the brushes totally lost their brush feature, becoming wrapped around the shaft. Three of the 5 snapped off.

The largest brush broke after using briefly. I haven’t used other sizes

Not very sturdy, 2 of the tools broke on first use.

Lost the first set then found it, works well.

Had second thought to buy but I did anyway. I works ideal for me. Gets the job done. Would definitely buy again and recommend.
