Abstract

PURPOSE: To heighten the efficiency of drilling, by inserting a hollow tube into a holder of a drill especially for deep hole and discharging chips together with cutting oil through the hollow tube and permitting of replacement of blade having cutting edge.
CONSTITUTION: The holder 30 is rotated relative to the workpiece while the cutting oil is supplied from the rear end of the holder 30 to a gap 39. The cutting oil cools and lubricates the cutting part of the holer 30 and is then drained rearward through the hollow tube 40. The chips enter into an outlet hole 33 and are then discharged together with the drained cutting oil to the rear end of the holder 30 through the hollow tube 40. Therefore, the chips do not become tangled with the holder 30 etc., and the cut hole surface is not scratched
