Weiler 36303 1/2 Inside Diameter, 5/8 Outside Diameter, 302 Stainless Steel Bristles, Turbo Tube Brush, Made in the USA

No good I was able to clean a single tube completely desatruding long the inside and the shaft turns on the plastic this is rubbish

Junk. Broke first use. Got replaced and that 1 broke first use

Ill never clean 1/2 copper pipe the old way again. This does a great job. Note that the two parts can be separated. The brush that cleans the inside of a fitting can be put on the drill by itself. I prefer it that way. I have a perfect hex shank that allows me to use the other brush by itself too. I prefer that. But, their intent is to keep the two parts together and extend and retract the inner brush depending on which you need. That should work fine unless both brushes are accidentally grabbing at the same time.

Im master plumber and this brush will make you money real fast

This seems like a clever device, but it is not effective. Use separate inside and outside brushes.

They work great. Clean the copper fast and clean ready for flux and solder no leaks.I bought two more for next time.

This item is not dependable.

Time saving tool, user friendly and convenient.

These really beat the old way of cleaning copper, no more emery paper, or cheap brushes. Run your drill slow and they will last a long time, just wear gloves to hang on to the pipe on the larger sizes. Works great.

While the concept is good the design/build is awful. Stripped the drive stem on the second pipe fitting.
