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.

First brush I tried was kaput in a minute...bristles all wound around wire....not good.

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

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.

Not suitable for heavy cleaning. Brushes collapse to shaft and the shaft breaks on the smaller sizes. Light duty only.

Total junk. Within 5 minutes of use, removing paint, most brush bristles came off. New one for comparison. Would NOT buy again.

I ordered these to use for cleaning the bore on brake caliper slide pins. Ive only used them twice and theyve worked perfectly both times. Makes the work so much easier.

They seem to do the job, however metal bristles permanently Bend and lose their shape.

Not a terribly robust design, but they do what they are supposed to do. I have worn out two so far, using them to get rust out of a complex piece of metalwork with a lot of crevices and corners. I have may leaned too hard on one, which after about 20 minutes snapped off at the base of the brush. I wore out the bristles on another one. But, they did the job a wire brush is supposed to do.
