What insert holders do you use for your tool? Pretty cool stuff!

wouldn't have been more economical just to weld a pipe onto a shank than to bore it all?

+meocats Concentricity is paramount to the success of these Trepanning drills. There is a 1mm clearance from the drill to the core and if the shank is not parallel o the Drill you will end up with the core jammed inside the tool.

weld it then machine it
