Abstract

PURPOSE: To forcibly press feed or discharge cutting oil, by providing screws in inner and outer circumferential sides of a hollow boring bar and rotating the bar, that is, the screws.
CONSTITUTION: There are provided a left hand screw 2 in small diameter in the inside of a hollow drilling tool 1 and a right hand screw 3 in large diameter in the outside. When the drilling tool 1 is rotated clockwise, cutting oil fed from the outside is fed by action of the screw 2 in the direction of an arrow mark 6 from the rear toward the front in the inside of the drilling tool 1, and fed to a cutting edge part mounted to the end of the drilling tool 1. The cutting oil changes its direction at the end as shown by an arrow mark 7 and is fed by action of the screw 3 in the direction of an arrow mark 10 toward the rear in the periphery of the drilling tool, then discharged to the outside of a hole. In this way, high pressure of feed oil is not required further feed oil and cutting oil discharge can be well performed.
