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)

Good construction.

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

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!

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

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.

I use these in my impact driver and with a hand tool to clean out bores while doing automotive repairs, they work great and are much more cost effective than buying off the tool trucks!

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

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

Great quality product will reorder as needed

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...
