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 great at first but then the brushes started to break off. Works good as lo as they work and not break

Very fragile only lasted about 2 minutes with light use then fall apart!

Im just using these to brush out golf club head hosels after the shafts are pulled. The wire is medium gauge and fine for getting most of the old epoxy out, but the wound shaft is too light duty. I had one break right below where the bristles start, and it was just barely over the hosel size. Ive bent 2 others (one larger, one smaller) which is fine if the shaft on the brush was heavier or more resilient but its obviously not. This is a case where you probably DO get what you pay for, and Ill spend more when I break these (likely wont take long) and buy from another manufacturer.

product does the trick. Great for cleaning small diameter copper pipes & other small delicate mechanical parts. Wish it came with a screw driver type handle.

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 am on a small project to re-conditioning all my house shower faucets with 27 years of calcium build up. So I bought this to use with my cordless drill and was able able to do this clean up in less than 5 minutes! what a time saver for sure! My only problem that I realized is these brush bits are bit short. but removing plumbings inner pipe calcium was easy and fast, including grinding down the inner part of the shower spout was peace of cake.

I am rehabbing an old Sears Table saw. I have taken it completely apart, and am in the process of re-assembling it. I have tried as much as possible to coat all the metal surfaces with some type of rust preventative. On the motor mount there are two rods which fit into the motor which I treated with clear Rustoleum paint. The rods needed to fit so I had to ream them out. These brushes worked perfectly

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

Lost the first set then found it, works well.

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.
