Default Draw bar tightening torque....

What is the spindle taper and what is the tooling in the spindle ?

MT3. End mill holder and drill chuck tapers. No collets.


Then I'd suggest it just needs to be tight enough to seat the taper . Get
out the torque wrench and do a few tests ... I know that a drill chuck in
the 3MT tailstock on my lathe will take quite a bit of torque , with no
drawbar at all . Just slid in firmly by hand .
