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

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.

Durable

These are alright. Once you use them a couple of times the bristles get matted down which makes them more difficult to use. I broke one as well. They bend easily as well so if you’re not trying to do any tough work these are fine. If you do something that requires some force these are not for you

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

complete junk. only after a couple of minutes of use, these brushes become deformed and totally useless. I would not buy them if they cost 2 cents.

Strong and easy to use. Am using 3 to 4 sizes for removing release agents from carbon fiber tube, before gluing inserts.

Within the first revolution the bristles were flat against shaft. They were useless

Nice, well constructed brushes. They worked perfectly for what I needed

They break off easily.

After a few & I mean a few minutes using VERY light pressure the tines began to compress. They no longer stick “out” therefore they no longer have the ability to abrade the surface you’re trying to remove rust, paint, scale, etc. from. Spend you’re $ elsewhere. If a company rep reads this, maybe I’ll be granted a refund.
