18-Piece Bore Brush Set- Stainless Steel Bore Brushes with 1/4 Hex Shank Twisted Wire Bore Brushes with Different Bristle Lengths for Tubes Ports Bearings Cleaning (8mm, 10mm, 12mm, 15mm, 17mm, 19mm)

Brushes look Very well Made Until You Actually Go To Use Them! Tried Two In a Milwaukee Drill On Slow Speed Setting In Brass Fitting. Both Broke In Less Than 15 Seconds! I Will Be Returning Them ! Absolute JUNK!

These brushes do a great job getting in tight areas. But be aware that they are not made to flex much. So if you get them in a bind, they will break. I will buy again.

Need to be careful not to put much lateral force on these or the center shaft will bend or break. If you’re careful to keep it centered they work very well.

These are fabulous for cleaning the rust and crud from antique and surplus rifles and pistols. Too harsh for everyday cleaning and maintenance, but when you’ve just unboxed that relic from Kathmandu, Addis Ababa, or Santiago these brushes will quickly get you to the point you can try different cartridges or do a chamber casting.

Great service, and the brushes seem to do the job quite well thanks

Great quality product will reorder as needed

Good construction.

Depending on how hard you use these, they could be good or not. I use them to clean the threads on used pipe fittings and they work fine. If you really pound them hard doing something, they probably wont last too long, but hey, they dont cost much either...

Works well for cleaning the rust out of your vehicles nuts.........!

The wire brush heads break off with very little force
