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 to tackle the most demanding drilling applications where extreme heat, hardness, and abrasion quickly destroy standard tools. Proudly made in the USA, this premium bit is crafted from M42 high-speed steel containing 8% cobalt, delivering exceptional red hardness and superior cutting strength under high-temperature conditions.
Engineered for Extreme Materials
Meeting stringent NAS 907J aerospace specifications, the Type 150 is built for precision drilling in challenging, work-hardened materials. It excels in stainless steel, hardened alloys, titanium, Inconel, Monel, high-nickel alloys, and abrasive plastics—materials that typically resist or rapidly dull conventional drill bits. The cobalt enrichment significantly enhances heat tolerance and edge retention, making it ideal for high-speed, continuous-use drilling environments.
Precision Starts with a 135° Split Point
The 135° split-point geometry provides rapid, accurate starts while reducing walking and eliminating the need for pilot holes. This design minimizes thrust pressure and improves stability, especially when drilling into hardened surfaces. The Type 150 performs best with rigid, positive-feed drilling systems, ensuring proper force application and maximizing tool life.
