Norseman Drill & Tool NAS 907J Type 150-ALN M42 Cobalt Twist Drill Bit
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 the ultimate choice for high-performance drilling in extreme temperature environments. Engineered to meet strict NAS 907J aerospace standards, this advanced twist drill is manufactured in the USA from M42 high-speed steel with 8% cobalt, offering exceptional red hardness and strength under the most demanding conditions.
What truly sets this bit apart is its Titanium Aluminum Nitride (TiAlN) coating—a premium dark-colored finish designed to withstand extreme heat and friction. This coating not only boosts oxidation resistance but also enables machining speeds up to 200% faster than uncoated bits, even when drilling hard metals like stainless steel, titanium alloys, and aerospace-grade materials.
The 135° split point delivers fast, precise starts with minimal walking and no need for a pilot hole. Combined with rigid, positive-feed drilling equipment, this bit offers unbeatable performance in high-speed production environments where efficiency and reliability are key.
