PURPOSE: To recover chips through absorbing function and remove the chips without interrupting working operation by providing a tool holder having the chip absorbing function on or near a spindle beforehand.
CONSTITUTION: A pin 8 at the tool holder 2 side is located by a block 9 and a tool holder 2 is attached to a spindle 1. When compressed air is sent from portion A under such condition, it flows in a pipe path of a tool along arrows B, C, D and is discharged from E to the atmosphere. Then, chips are absorbed from an end of a nozzle 4 by negative pressure of the air passing through portion D to be discharged from portion E. In the case of a deep hole, compressed air branched from portion C is blasted from an auxiliary nozzle 5 mounted near an end of a nozzle 4 to the interior of said deep hole through a tube 6 and , so that chips curled up are absorbed through the nozzle 4.
