Norseman Drill & Tool NAS 907B Jobber Length Twist Bits
Precision-Crafted for Aerospace-Grade Performance
The Norseman Drill & Tool NAS 907B Jobber Length Twist Bits are engineered to deliver exceptional accuracy, durability, and consistency for demanding aerospace and industrial applications. Made in the USA and manufactured to strict NAS 907B specifications, these premium drill bits ensure precise, repeatable performance for professionals who rely on uncompromising quality.
Built for Strength and Heat Resistance
Premium HSS for Tough Materials
Crafted from high-speed steel (HSS), the NAS 907B series offers outstanding hardness, heat resistance, and edge retention. These attributes make the bits ideal for drilling into:
-
Stainless steel
-
Alloy steels
-
Titanium
-
High-strength metals used in aerospace and precision manufacturing
The rugged construction ensures dependable performance, even under high-speed or high-pressure drilling conditions.
135° Split Point for Accurate, Walk-Free Starts
Enhanced Control and Hole Quality
Featuring a 135° split point, the NAS 907B bits deliver fast, accurate starts with reduced walking—critical for precision metalworking. This geometry lowers thrust requirements, improves hole accuracy, and increases efficiency in both hand-held tools and CNC or production drilling setups.
Precision-Ground Flutes & Advanced Finish
Improved Chip Flow and Extended Tool Life
Each bit is precision-ground to strict tolerances, ensuring smooth operation, balanced rotation, and longer tool life. The refined flute geometry enhances chip evacuation, minimizing heat buildup and maintaining sharp cutting edges during continuous use.
The black and gold oxide finish increases lubricity, reduces wear, and provides corrosion resistance, ensuring consistent performance across diverse materials and environments.
