Norseman Drill & Tool NAS 907J Type 150-ALN Letter Sizes M42 Cobalt Twist Drill Bit
Norseman Drill & Tool NAS 907J Type 150-ALN Letter Sizes M42 Cobalt Twist Drill Bit: High-Speed Drilling for Extreme Conditions
The Norseman Drill & Tool NAS 907J Type 150-ALN Letter Sizes M42 Cobalt Twist Drill Bit is built for professionals who require maximum tool life, heat resistance, and precision in high-demand environments. Engineered in the USA to meet stringent NAS 907J aerospace standards, this drill bit is crafted from M42 high-speed steel with 8% cobalt, offering exceptional red hardness and cutting performance.
What sets the Type 150-ALN apart is its advanced Titanium Aluminum Nitride (TiAlN) coating, formulated for extreme temperature resistance and superior wear protection. This coating allows for machining speeds up to 200% faster than uncoated bits and helps reduce friction and oxidation—making it ideal for drilling stainless steel, titanium alloys, hardened steels, and other difficult-to-machine materials.
The 135° split point ensures quick, walk-free starts without the need for a pilot hole, while precision-ground flutes aid in chip removal and cooler cutting. The letter size configuration provides non-standard, precise diameters ideal for aerospace, automotive, and custom manufacturing applications where tight tolerances are critical.
