Norseman Drill & Tool NAS 907J Type 150 M42 Cobalt Twist Drill Bit
Norseman Drill & Tool NAS 907J Type 150 M42 Cobalt Twist Drill Bit: Built for Heat, Hardness, and High-Performance Drilling
The Norseman Drill & Tool NAS 907J Type 150 M42 Cobalt Twist Drill Bit is engineered for the toughest drilling jobs. Manufactured in the USA from premium M42 high-speed steel with 8% cobalt, this bit delivers superior red hardness, making it ideal for applications where high heat and abrasive materials would destroy ordinary tools.
Designed to meet strict NAS 907J aerospace standards, the Type 150 cobalt drill bit is optimized for precision drilling in hard, work-hardened materials like stainless steel, titanium alloys, Inconel, and even certain abrasive plastics. The addition of cobalt increases the tool’s resistance to heat and wear, allowing it to maintain cutting edge integrity in high-speed and high-pressure environments.
The 135° split point provides quick, accurate starts with reduced walking, eliminating the need for pilot holes. This bit excels when used with rigid, positive feed drilling equipment, which ensures consistent pressure and maximum tool life in demanding industrial and aerospace settings.
