I am using a Delta twin pully 16 inch press that used to drill the other half of the delignit block two years ago. Afterwhich, I have used hard rock maple blocks. I did not want to let this block go to waste. It may be the last delignit I drill. I don't know the torque of the motor. I'll have to check. Bit is TIGHT in chuck.
