Great product works well

About 50% arrived bent. Really? On a drill how well do bent drill bits work? Not well and they are dangerous. Get a better brand. Returning them.

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!

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...

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 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.

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.

Great quality product will reorder as needed

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.

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