6pcs HVAC Repairing Set Air Conditioner Copper Tube Expander Swaging Tool Manual Pipe Swage Expander Drill Bit Soft Copper Tubing Bit with 1/4'', 3/8'', 1/2'', 5/8'', 3/4'', 7/8' Bits

this is great, I should have both this a long time ago . work grate

Muy buena pieza de trabajo, facilita mucho la unión de tuberías sin tanto esfuerzo, buena calidad.

For the price I’m actually surprised they work. I did have to take the 7/8 bit and the 3/4 bit to the grinder and clean up the hex ends so they lock into the impact. Only other issue is they leave the inside of the copper fairly rough. But overall not bad.

I liked it

Good product

I tried to use these on a job last week and had multiple issues due to the quality. The hex bit end doesn't fit an impact driver. You can only fit it in a drill. The tolerances are just too sloppy. In addition to that, the size of the tube after swaging was too large on the 3/4 pipe I tried it on. I'm thankful I also orders a mechanical swager otherwise I would have had poor connections.

This product works, but the quality of the swaging drill bits is not as good as expected. You will receive them in a small plastic bag. I ordered these 6 pcs. copper swaging drill bits together with a 5 in 1 conical drill swaging tool. The 5 in 1 drill swaging tool has a better build quality and also works much better than these swaging drill bits, probably because of the slightly different form.

Was able to redo a water heater pipes without buying more pipe
