Norseman Drill & Tool HD Super Premium Reduced Shank NAS 907B Type 128-AG Jobber Length Twist Bit
Norseman Drill & Tool HD Super Premium Reduced Shank NAS 907B Type 128-AG Jobber Length Twist Drill: Heavy-Duty Power and Precision Engineering
The Norseman Drill & Tool HD Super Premium Reduced Shank NAS 907B Type 128-AG Jobber Length Twist Drill is designed for superior strength, accuracy, and versatility in the toughest industrial applications. Proudly made in the USA, this professional-grade drill bit meets NAS 907B aerospace standards, delivering exceptional precision and long-lasting performance in metalworking, fabrication, and maintenance operations.
Constructed from high-molybdenum tool steel, the 128-AG drill bit is treated with Norseman’s exclusive Magnum nitro-carburized finish, enhancing surface hardness, lubricity, and wear resistance. This advanced treatment allows the bit to outperform cobalt drills in work-hardening materials like stainless steel, titanium, and high-tensile alloys.
The reduced shank design enables drilling of larger holes in standard 3/8" or 1/2" capacity chucks, eliminating the need for larger, more expensive equipment. This makes it ideal for portable drilling operations where versatility and power are required.
Featuring a 135° split point, the Norseman Type 128-AG ensures fast starts, accurate holes, and reduced walking on curved or hard surfaces. The precision-ground flutes optimize chip evacuation and maintain cooler cutting temperatures, extending tool life and improving productivity in demanding shop conditions.
