Norseman Drill & Tool NAS 907J Type 150 Letter Sizes M42 Cobalt Twist Drill Bit

Precision Meets Power for Aerospace-Grade Drilling

The Norseman Drill & Tool NAS 907J Type 150 Letter Size M42 Cobalt Twist Drill Bit is engineered for professionals who require uncompromising precision, durability, and heat resistance. Manufactured in the USA to meet strict NAS 907J aerospace specifications, this premium drill bit is produced from M42 high-speed steel with 8% cobalt, delivering exceptional red hardness, wear resistance, and extended tool life in extreme drilling conditions.

Designed specifically for demanding materials, the Type 150 excels when drilling stainless steel, titanium, tool steels, and high-strength alloys. Its letter size configuration provides precise, non-fractional diameters that bridge the gap between standard fractional and number sizes, making it ideal for aerospace, automotive, medical device manufacturing, and precision fabrication where exact hole sizing is critical.

Engineered for Accuracy and Efficiency

Each Type 150 drill bit features a 135° split point, allowing for fast, self-centering starts without walking. This eliminates the need for pilot holes, saving valuable setup time while improving positional accuracy. Precision-ground flutes are optimized for smooth chip evacuation, reducing heat buildup and promoting cooler cutting—especially important in hard metals and continuous drilling operations.

The combination of cobalt metallurgy and precision geometry ensures consistent performance under high RPMs and positive-feed conditions, making this drill bit a trusted choice for mission-critical applications.
