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 Size M42 Cobalt Twist Drill Bit is engineered for professionals who demand extreme accuracy and durability when drilling small, precise holes in hard materials. Manufactured in the USA to stringent NAS 907J aerospace specifications, this premium drill bit is produced from M42 high-speed steel with 8% cobalt, delivering exceptional red hardness, edge stability, and resistance to heat buildup in demanding applications.

Built for High Heat and Tight Tolerances

What sets the Type 150-N apart is its Titanium Nitride (TiN) coating. This advanced coating reduces friction, improves lubricity, and allows the bit to run cooler at higher speeds—extending tool life by up to five times compared to uncoated cobalt drills. The result is improved productivity, fewer tool changes, and consistent hole quality in stainless steel, titanium alloys, hardened steels, and other tough-to-machine materials.

The wire gauge sizing provides ultra-fine diameter control, making this drill bit ideal for aerospace components, electrical assemblies, medical devices, and precision fabrication where tight tolerances are critical. These exact sizes ensure reliable fitment for pins, fasteners, and precision hardware.

Designed for Accuracy and Efficiency

A 135° split point geometry allows for fast, self-centering starts and eliminates walking, removing the need for pilot holes. Precision-ground flutes promote smooth chip evacuation, reducing heat buildup and helping maintain sharp cutting edges—especially when used with rigid setups and positive-feed drilling equipment.
