SAWTOOTH DRILL PREVENTING DUST FROM CFRP PROCESSING

摘要

A sawtooth drill (1) is mounted on a hand drill machine or a milling machine, before being fixated with a collet (6) and a nut (5) for processing. Therefore, twisting due to rotation is prevented because only the sawtooth drill is rotated by a bearing (4) of a cap for processing. Moreover, dust produced hereat is prevented from flying by the cap, and is discharged to a dust collecting apparatus on the outside through a valve (3).;COPYRIGHT KIPO 2019
