Spiral groove

S - type spiral groove helps to remove chips easier and work more efficient.

118° and 135° split points

118 drill bits are more suitable for soft materials cutting,like mild steel or cast iron.
 135 drill bits are suitable for hard steel,especially for hole diameter 4times as the drill bits’ diameter.The thick chips
 produced when cut hard materials reduce the working hardening of the cavity.
