Norseman Drill & Tool Magnum Super Premium NAS 907B Type 170-AG Jobber Length Metric Twist Bit
Precision, Speed, and Heat-Resistant Performance
The Norseman Drill & Tool Magnum Super Premium NAS 907B Type 170-AG Jobber Length Metric Twist Bit is engineered for elite professionals who require uncompromising accuracy, speed, and durability. Proudly Made in the USA, this drill bit meets stringent NAS 907B aerospace specifications, guaranteeing superior performance in demanding industrial and manufacturing environments.
Built for Extreme Materials
Crafted from premium high-molybdenum tool steel, the Type 170-AG is designed to maintain exceptional hardness and edge retention, even at elevated drilling temperatures. This advanced metallurgy allows the bit to excel in stainless steel, hardened alloys, titanium, and other high-strength materials where conventional drills fail prematurely. Its ability to stay sharp under heat-intensive conditions makes it a standout choice for aerospace, fabrication, and precision machining.
Superior Cutting Design
Equipped with a 135° self-centering split point, this metric jobber bit delivers fast, accurate starts without requiring a center punch. The design minimizes walking on curved or hardened surfaces, reduces thrust pressure, and ensures consistent, efficient penetration. Precision-ground flutes optimize chip evacuation and maintain cooler cutting temperatures, improving tool life and overall productivity.
Advanced Surface Treatment
The black and gold oxide finish enhances lubricity, improves corrosion resistance, and reduces friction for smooth, controlled drilling. This finish supports high-speed drilling in continuous-use environments by promoting better heat dissipation and maintaining cutting-edge integrity.
