Application

metal drilling.

Material

HSS (high speed steel) is a tool steel that features a high rigidity, high abrasion resistance and heat resistance, and it often used as the raw material for metal cutting tools require a higher sharpness.

Feature

The temperature will be high while grinding, as will the high speed steels’ rigidity.
