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

Aerospace-Grade Performance for Demanding Materials

The Norseman Drill & Tool NAS 907J Type 150 M42 Cobalt Twist Drill Bit is engineered for professionals who demand maximum performance, precision, and durability when drilling tough metals. Manufactured in the USA and built to meet stringent NAS 907J aerospace specifications, this premium drill bit delivers consistent results in high-heat, high-stress applications where standard high-speed steel tools fall short.

Constructed from M42 cobalt high-speed steel with 8% cobalt, the Type 150 drill bit offers exceptional red hardness, superior wear resistance, and extended tool life. It is specifically designed for drilling hard and abrasive materials such as stainless steel, titanium, Inconel®, tool steels, and high-strength alloys commonly found in aerospace, automotive, and precision manufacturing environments.

Precision Design for Accuracy and Efficiency

The Type 150 features a 135° split point geometry, allowing for fast, accurate starts with minimal walking. This eliminates the need for pilot holes, saving time while improving hole location accuracy. Precision-ground flutes ensure efficient chip evacuation, reducing heat buildup and helping maintain a sharp cutting edge during extended drilling cycles.

Available in fractional sizes, these drill bits provide exact compatibility with U.S. standard hole dimensions, making them ideal for shops working with SAE fasteners, components, and prints.
