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 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.

Good construction.

These do not hold up well at all. They bend and break very easily.

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

The wire brush heads break off with very little force

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.

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

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