6pcs Copper Tube Pipe Cleaner, 1/2” 3/4” 1” Pipe Cleaning Brush Set, Stainless Steel Wire Bore Brushes for Power Drill, 1/4 Inch Hex Shank

2 snapped off first go.

no se si en USA los diametros para tuberias sean mas reducidos pero probe las escobillas en tubos de cobre de 1/2, 3/4 y 1 plg y quedan muy reducidas, por lo que no cumplen su funcion. espero que las otras que compre

I’m pretty sure if you got a sizable job to do. I would suggest buying these, the work well and are fast clean

Very effective brushes.

They work great, but the sizes are wrong for copper pipe fittings. You have to go up a size for each pipe fitting. The "1 inch" brushes fit 3/4 inch pipe, the "3/4 inch" brushes fit 1/2 inch pipe, and the "1/2 inch" brush is essentially useless. They seem to be assuming you're cleaning off the inside of the pipe itself, not the inside of the fittings, which is not how copper plumbing works. It's still better than just cutting the ends off a disposable pipe cleaning brush, especially when you have to switch back and forth between inner and outer cleaning brushes, and using a drill with a quick-disconnect bit holder. If you're never using 1" copper pipe, this still works fine, but two of the six brushes are wasted since nobody is soldering fittings smaller than 1/2".
