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 designed for professionals who need extreme durability, precision, and heat resistance in demanding drilling applications. Manufactured in the USA to strict NAS 907J aerospace specifications, this drill bit is made from M42 high-speed steel with 8% cobalt, delivering exceptional red hardness and wear resistance in high-heat, high-pressure conditions.
What sets the Type 150-N apart is its Titanium Nitride (TiN) coating, a hard, lubricious finish that reduces friction, increases wear resistance, and allows for longer tool life—up to 5X more than uncoated bits. This makes it ideal for repetitive drilling in tough materials such as stainless steel, titanium, tool steels, and high-strength alloys.
The 135° split point ensures fast, walk-free starts and precise hole positioning without a pilot hole. Combined with rigid, positive-feed drilling equipment, the bit performs reliably in high-speed, high-torque environments where precision and consistency are critical.
