SPINS6000 6-Piece Drill Bit Swaging Tool Set 1/4, 3/8, 1/2, 5/8, 3/4, 7/8-Inch

Saves money, saves you, works very well, pair with a tubing bender and make your own fittings

High quality grade swage set. Just get it if you are hvac installer and need a high quality set.

These bits are quality tools. There are other knock offs out there for more and less $$$. Save the grief and get these. They are made of quality material that lasts. I bought these because I have used a them before borrowed from a co-worker and they work great. A huge timesaver for swaging tubing. Absolutely a must for HVAC work!!! Other brands are usually made with a smaller shank that breaks easy. Just read the use instructions and be sure to use a compatible chuck type drill and NOT in hammer/impact mode. Simply great product.

so far working fine

Works super well and at parts store like RSD charging almost 300$ for a set like these

Tried the cheap import first because I only needed to do 3 connections, No-Go. Bought the full SPIN kit but only used the 3/8 and 7/8 so far. Make sure to read and follow the instructions about RPM. Worked great on both sizes but you better hang on to the larger size tubes and the drill because the torque reaction is pretty big. Also creates a lot of heat, even with lubricating oil. A good, quality tool set.

When you ran out of copper coupler this is best choice for it.Great tool

Compré estos espancionadores porque son buenos pero también por el estuche pequeño que se muestran en las fotos y me llegaron en una caja enorme para mi gusto, ese estuche no cabe en el equipo de soldar como el otro estoy muy desepcionado no es lo que esperaba.
