Abstract
A drill is capable of forcibly aspirating and discharging chips to prevent environmental contamination as well as to simplify cleaning the chips. The drill has an intake hole and an opening formed therein so that the aspiration takes place through the intake hole and the chips generated in the cutting process can forcibly be aspirated from the opening. Because the chips can be discharged without using cutting fluid, the drill is useful for preventing environmental contamination. Moreover, as the chips are forcibly aspirated from the opening and discharged through the intake hole, the chips are not scattered around a workpiece under the cutting process and cleaning the chips can become simple and easy.
