Norseman Drill & Tool Letter Sizes HSS Heavy-Duty NAS 907B Type 190-ALN Titanium Aluminum Nitride Jobber Length Twist Bit
Norseman Drill & Tool Letter Sizes HSS Heavy-Duty NAS 907B Type 190-ALN Jobber Length Twist Bit: TiAlN-Coated Strength for Extreme Heat and Precision Drilling
The Norseman Drill & Tool Letter Sizes HSS Heavy-Duty NAS 907B Type 190-ALN Jobber Length Twist Bit is built for professionals who require maximum precision, durability, and performance in demanding drilling conditions. Proudly made in the USA, this premium drill bit is manufactured to NAS 907B aerospace-grade standards, ensuring accuracy, consistency, and long tool life in industrial and manufacturing environments.
Engineered from premium high-speed steel (HSS), the Type 190-ALN is designed to withstand high torque and extreme heat while drilling through tough materials such as stainless steel, titanium, Inconel, and hardened alloys. The 135° self-centering split point provides fast, accurate starts with reduced thrust, eliminating walking and ensuring cleaner, more precise holes.
The advanced Titanium Aluminum Nitride (TiAlN) coating gives this bit exceptional hardness, lubricity, and oxidation resistance. The coating forms a heat-resistant aluminum oxide layer during use, allowing for higher cutting speeds and superior performance at elevated temperatures. This makes it ideal for high-speed machining and dry drilling applications where heat management and tool longevity are critical.
Each bit is precision-ground to tight aerospace tolerances for balance, stability, and consistent hole sizing. Available in letter-size increments, it’s perfect for professionals who demand precise sizing and reliable performance.
