Feature:
Alloy steel is preferred, which has higher hardness and wear resistance than ordinary drill bits.
Cut resistance is small, and punching is accurate and effortless. After centerless grinding treatment, the surface of the drill body is smoother in drilling and chip removal.
The drill shank is cut into solid hexagon, which makes the electric drill hold more tightly and the drilling is not easy to slip.
