Norseman Drill & Tool NAS 907J Type 150-ALN M42 Cobalt Twist Drill Bit
Built for Extreme Heat, Maximum Speed
The Norseman Drill & Tool NAS 907J Type 150-ALN M42 Cobalt Twist Drill Bit is engineered for elite-level drilling performance in environments where heat, pressure, and precision push tooling to the limit. Manufactured in the USA and built to strict NAS 907J aerospace specifications, this premium drill bit is crafted from M42 high-speed steel with 8% cobalt, giving it exceptional red hardness and edge retention during high-speed, high-temperature machining.
TiAlN Coating for Unmatched Heat Resistance
What makes the Type 150-ALN truly stand out is its Titanium Aluminum Nitride (TiAlN) coating—a dark, ultra-hard finish specifically designed to withstand extreme thermal conditions. TiAlN dramatically increases oxidation resistance, enabling the bit to run up to 200% faster than uncoated cobalt drills while maintaining its cutting integrity. This advanced coating excels in severe drilling applications involving stainless steel, titanium alloys, heat-resistant superalloys, and aerospace-grade materials.
Precision Starts with a 135° Split Point
The bit’s 135° split point provides quick, accurate, walk-free starts, eliminating the need for a center punch or pilot hole. When paired with rigid, positive-feed drilling equipment, the Type 150-ALN delivers smooth penetration, reduced thrust, and exceptional consistency—ideal for high-production environments where speed and reliability are mission critical.
