Norseman Drill & Tool NAS 907J Type 150-N Letter Sizes M42 Cobalt Twist Drill Bit: TiN-Coated Precision for Demanding Applications
The Norseman Drill & Tool NAS 907J Type 150-N Letter Sizes M42 Cobalt Twist Drill Bit delivers elite performance, unmatched durability, and precise sizing for professionals working in high-demand environments. Made in the USA to meet strict NAS 907J aerospace standards, this premium drill bit is crafted from M42 high-speed steel with 8% cobalt, offering superior red hardness and wear resistance for drilling tough metals under extreme heat.
Enhanced with a Titanium Nitride (TiN) coating, the Type 150-N provides reduced friction, cooler cutting, and a dramatic increase in tool life—up to 5X longer than uncoated equivalents. The letter size configuration allows for precise, non-fractional hole diameters, ideal for aerospace, automotive, defense, and high-tolerance industrial applications.
The 135° split point ensures fast, accurate starts without walking, eliminating the need for a pilot hole and improving drilling efficiency. When used with rigid, positive-feed drilling equipment, this bit delivers consistent, high-performance results in stainless steel, titanium alloys, tool steels, and other hard-to-machine materials.
