Features
- Constructed of M-42 5% cobalt high speed steel for super abrasive resistance in tough metals
- Heavy duty spiral flute design produces faster chip ejection
- Shorter cutting lips reduce torque for drilling in high tensile strength materials
- 135 deg split point reduces feed pressure for easier penetration without work hardening
- Cobalt is harder than high speed steel and provides better wear resistance
- It is commonly used on high tensile alloys
- Bright provides a smooth, polished finish on the tool
- It increases chip flow in softer materials such as aluminum, wood and plastic
- The shank is smaller than the drill bit diameter
- Recommended for drilling hardened steel, super alloys, titanium and stainless steel
