Useful

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 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.

I liked it

Good product

What can I say, they work as intended.
