Norseman Drill & Tool HSS Heavy-Duty NAS 907B Type 190-ALN Jobber Length Twist Bit
Norseman Drill & Tool HSS Heavy-Duty NAS 907B Type 190-ALN Jobber Length Twist Bit: TiAlN-Coated Power for Extreme Drilling Performance
The Norseman Drill & Tool HSS Heavy-Duty NAS 907B Type 190-ALN Jobber Length Twist Bit is built for professionals who demand superior performance, strength, and longevity in high-speed and high-temperature drilling applications. Proudly made in the USA, this precision-engineered bit meets NAS 907B aerospace specifications, ensuring consistent quality, accuracy, and reliability for industrial and manufacturing use.
Constructed from premium high-speed steel (HSS), the Type 190-ALN is designed for drilling hard, abrasive materials such as stainless steel, titanium, and high-tensile alloys. Its 135° self-centering split point ensures fast, accurate starts while reducing thrust and eliminating walking—perfect for precision drilling in tough metals.
The advanced Titanium Aluminum Nitride (TiAlN) coating provides outstanding wear resistance, heat protection, and surface hardness. This ultra-durable coating forms a protective aluminum oxide layer during use, allowing the bit to operate at higher cutting speeds and temperatures without losing its edge. The result is extended tool life, improved lubricity, and enhanced performance in dry or high-friction drilling conditions.
Each bit is precision-ground to aerospace-grade tolerances for exceptional balance, chip evacuation, and hole accuracy. The Type 190-ALN is the ideal solution for demanding drilling operations where heat and wear resistance are critical.
