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!

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 were just what I needed for rebuilding the support bracket on my disk brakes. The guide pins were stuck in place when I took them apart and wouldnt go back in smoothly after cleaning just the pin. I was able to clean out the support bracket with these brushes and put the guide pins back in smoothly. Im sure Ill find other uses for them around the car.

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...

Work great for everything from brake slide pin sockets to barrel bore cleaning

Works very well removing rust or anything unwanted that causes clog.

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

Refinished some lawn furniture, got into some tight spots. Work excellent!

The wire brush heads break off with very little force

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