Norseman Drill & Tool NAS 907J Type 150-N Wire Gauge Sizes M42 Cobalt Twist Drill Bit: TiN-Coated Precision for Tough-to-Drill Materials

The Norseman Drill & Tool NAS 907J Type 150-N Wire Gauge Sizes M42 Cobalt Twist Drill Bit is built for exacting work in aerospace, automotive, and industrial environments where small, precise holes in tough materials are required. Manufactured in the USA to meet strict NAS 907J aerospace specifications, this drill bit is made from M42 high-speed steel with 8% cobalt, providing exceptional red hardness and performance in high-heat applications.

The standout feature of the Type 150-N is its Titanium Nitride (TiN) coating, which reduces friction, improves lubricity, and significantly extends tool life—up to 5X longer than uncoated alternatives. This makes it ideal for stainless steel, titanium alloys, hardened steels, and even abrasive plastics.

Precision matters, and that’s why this drill bit is offered in wire gauge sizes, allowing for ultra-fine hole diameters perfect for tight-tolerance machining, electrical component drilling, and medical-grade fabrications. The 135° split point ensures walk-free starts and eliminates the need for pilot holes, while the precision-ground flutes help evacuate chips efficiently to keep cutting edges cool and sharp.
