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

Bore brushes are very good quality and work fine for my application!

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

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.

Wear out and bend very quickly

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

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

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.

ITS ALL JUNK USE THE IN THE DRILL FOR ABOUT 2 MIN ONE OF THEM BROKE. ALL THE REST WORE WITHIN A HOUR.

Well built brushes, work great for hard to reach places.

I used this on a power drill to clean out brake caliper bolt threads and other threads on the calipers. They didnt last long when applying pressure. Broke right at the shaft end where the brush attached to the base the fits into a drill. Too flimsy! Waste of money!
