RED COBALT – HSS-Ground – DIN 338 Cobalt metal drill bits 2pc.
Metal drill bits ground from solid, extremely heat resistant 5% cobalt-alloyed high speed steel produced according to DIN 338.
Suitable for drilling high alloy content steels and metals with tensile strengths over 1000 N/mm² like stainless steel.
QUAD EDGE™ Tip: unique combination of 135° split point and four cutting edges: 135° split point allows for precise & fast drilling start without walking. Four cutting edges create smaller chips to prevent heat build up for longer life.
Variable flute geometry: For faster material ejection. Helps the bit run cooler and prevent it from burning out faster.
Enhanced tapered web: Wider core towards the shank of the drill bit. Strengthens the core to increase overall flute durability.
3-flat shank from ? 5 mm for better grip and prevents chuck slippage.
Colour: bronze.
