Cartridge Roll Mandrel

Great product and service

A nice mandrel

These mandrel appear to be well made. I wished I could get them in 1/4”shank though. My only negative on these

Figured out how to use

I bent the first one setting my speed too high and approaching the part at a severe angle. Once I figured that out and slowed down the RPM and watch my approach angle, the second mandrel is still working well. This a great solution for cleaning up inside corner welds.
