钢件断屑钻头(如图所示)系根据普通麻花钻头改革而成。它和标准群钻的不同处是在钻头切削部分磨出对称的分屑槽和断屑台,能达到理想的排屑效果。该钻头适用于各种钢件孔的成批加工,并能钻削实际生产中常遇到的孔深为孔径5～8倍左右的一般深孔,是一种便于手工刃磨,应用范围较广的钻头。 Steel chip breakage drill (shown) is based on ordinary twist drill made. It is different from the standard group drilling is the symmetrical chip breaker and chip breaking table in the cutting part of the drill, to achieve the desired chip removal. The drill for a variety of steel hole batch processing, drilling and drilling can often encountered in the production of the hole depth of about 5 to 8 times the general deep hole, is a hand-grinding, a wide range of applications Drill bit.
