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

Engineered for Precision, Built for Speed

The Norseman Drill & Tool NAS 907J Type 150-ALN Wire Gauge Size M42 Cobalt Twist Drill Bit is purpose-built for ultra-precise drilling in extreme machining environments. Manufactured in the USA to demanding NAS 907J aerospace standards, this premium drill bit is produced from M42 high-speed steel with 8% cobalt, delivering exceptional red hardness, edge strength, and wear resistance when drilling at elevated temperatures.

Advanced TiAlN Coating for Extreme Heat Applications

What truly sets the Type 150-ALN apart is its Titanium Aluminum Nitride (TiAlN) coating, engineered for high-speed, high-temperature cutting. TiAlN dramatically reduces friction and oxidation while forming a protective aluminum oxide layer during operation. This allows machining speeds up to 200% faster than uncoated cobalt drill bits, while significantly extending tool life in dry or low-lubrication environments.

This coating makes the Type 150-ALN ideal for drilling stainless steel, titanium alloys, hardened steels, and abrasive aerospace-grade materials, where conventional drill bits quickly lose their cutting edge.

Wire Gauge Precision for Tight Tolerances

Offered in wire gauge sizes, this drill bit is designed for small-diameter, high-accuracy hole drilling. These precise sizes are essential for applications in aerospace components, electronics, medical devices, and precision industrial manufacturing, where tolerances are extremely tight and consistency is critical.

A 135° split point ensures fast, self-centering, walk-free starts without the need for pilot holes. Precision-ground flutes enhance chip evacuation and heat control, improving surface finish and extending tool life during continuous production runs.
