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

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

TiN-Coated for Maximum Performance and Longevity

The Norseman Drill & Tool NAS 907J Type 150-N Fractional Sizes M42 Cobalt Twist Drill Bit is engineered for professionals who demand extended tool life, precise hole placement, and consistent performance in extreme drilling environments. Manufactured in the USA to exacting NAS 907J aerospace specifications, this premium drill bit is built from M42 high-speed steel with 8% cobalt, providing outstanding red hardness, edge stability, and resistance to heat and wear.

What elevates the Type 150-N above standard cobalt drills is its Titanium Nitride (TiN) coating. This ultra-hard, gold-colored coating reduces friction, minimizes heat buildup, and significantly improves wear resistance—often delivering up to five times the service life of uncoated drill bits. The result is faster cutting speeds, smoother drilling, and reduced downtime in high-production environments.

Designed for Precision in Hard Materials

Fractional sizing ensures compatibility with standard U.S. hole dimensions, making the Type 150-N ideal for aerospace, automotive, industrial, and precision manufacturing applications. It excels in drilling stainless steel, titanium, tool steels, cast iron, and high-strength alloys where conventional bits lose hardness or dull prematurely.

A 135° split point geometry provides immediate self-centering and walk-free starts, eliminating the need for pilot holes and improving positional accuracy. Precision-ground flutes enhance chip evacuation, keeping cutting edges cooler and extending tool life—especially when used with rigid setups and positive-feed drilling equipment.
