Norseman Drill & Tool NAS 907J Type 150-ALN Fractional Sizes M42 Cobalt Twist Drill Bit

Norseman Drill & Tool NAS 907J Type 150-ALN Fractional Sizes M42 Cobalt Twist Drill Bit

Built for Speed, Strength, and Extreme Heat

The Norseman Drill & Tool NAS 907J Type 150-ALN Fractional Size M42 Cobalt Twist Drill Bit is engineered for professionals who push tooling to the limit. Manufactured in the USA to stringent NAS 907J aerospace standards, this high-performance drill bit is produced from M42 high-speed steel with 8% cobalt, delivering exceptional red hardness, edge strength, and wear resistance in the most demanding drilling environments.

Advanced TiAlN Coating for Extreme Performance

What truly sets the Type 150-ALN apart is its Titanium Aluminum Nitride (TiAlN) coating. Designed for extreme heat applications, TiAlN forms a protective aluminum oxide layer at elevated temperatures, allowing the tool to run hotter without breaking down. This enables machining speeds up to 200% faster than uncoated cobalt drills, while reducing friction, oxidation, and premature wear.

The result is longer tool life, higher productivity, and consistent hole quality when drilling stainless steel, titanium alloys, tool steels, and other hard metals. TiAlN-coated drills excel in dry or minimal-lubrication environments, making them ideal for high-speed, high-efficiency production settings.

Precision Design for Reliable Results

A 135° split point ensures fast, self-centering starts with no walking, eliminating the need for pilot holes and improving accuracy. Precision-ground flutes optimize chip evacuation and heat control, especially when used with rigid setups and positive-feed drilling equipment. Offered in fractional sizes, the Type 150-ALN provides compatibility with standard U.S. dimensions for broad application across aerospace, automotive, and industrial machining.
