Equal shank dril M2
Baked cobalt and other shank drills commonly refer to cobalt alloy high-speed steel drill bits (for example, M35 or M42 cobalt steel drill bits). They are drill bits that are hardened using special heat treating processes (e.g., high temperature tempering/"cobalt" process). Its features are:
Material
Based on high-speed steel (HSS), 5%-8% cobalt (5% cobalt in M35 and 8% cobalt in M42) is added to improve high temperature toughness and hardness.
Process
After high-temperature heat treatment ("baked cobalt"), the cobalt element is evenly distributed, and the metal structure is further strengthened.
Design
Generally straight or tapered shank, suitable for high load drilling conditions
