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

Great for automotive brakes, faucet inside diameter cleaning of scale removal, when replacing a cartridges.

Durable

These are pretty flimsy and break quickly they are not a great buy.

One broke so not very sturdy cheap metal

I received yesterday and used the 19mm brush to clean light rust from some 3/4-10 internal threads. The brush came apart within less than a minute of use. I had high hopes for these brushes. Very disappointed.

3 brushes broke in 2 minutes. Complete garbage.

The wire bristles wore or broke off right away. I used the two smaller ones and they’re already done. Can’t use too much pressure while grinding or the bristles will break off easily. Maybe I didn’t use them correctly. Who knows but this will more than likely be my last purchase.

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

As you can see in the pictures the bristles literally spun right out of the bit after using them for about 20 seconds. I was really disappointed in this purchase and now I know why they were somewhat inexpensive.
