Norseman Drill & Tool Fractional Sizes HSS Heavy-Duty NAS 907B Type 190-ACN Titanium Carbon Nitride Jobber Length Twist Bit
Norseman Drill & Tool Fractional Sizes HSS Heavy-Duty NAS 907B Type 190-ACN Jobber Length Twist Bit: TiCN-Coated Strength for Precision and Durability
The Norseman Drill & Tool Fractional Sizes HSS Heavy-Duty NAS 907B Type 190-ACN Jobber Length Twist Bit is engineered to deliver exceptional strength, accuracy, and tool life in the most demanding drilling environments. Proudly made in the USA, this heavy-duty drill bit meets NAS 907B aerospace specifications, guaranteeing precision, consistency, and reliability for industrial, fabrication, and maintenance professionals.
Manufactured from premium high-speed steel (HSS), the Type 190-ACN is designed to withstand the toughest drilling conditions, including stainless steel, titanium, and hardened alloys. Its 135° self-centering split point provides fast, accurate starts, reduces thrust, and prevents walking—ensuring smoother drilling and cleaner hole finishes.
The Titanium Carbon Nitride (TiCN) coating sets this bit apart by significantly improving surface hardness, lubricity, and heat resistance. This advanced coating technology allows for higher cutting speeds, enhanced chip flow, and cooler operation, making it ideal for continuous or high-speed drilling. TiCN’s superior wear protection ensures extended tool life, consistent performance, and reduced downtime.
Each bit is precision-ground to aerospace-grade tolerances for perfect balance, smooth operation, and accurate hole sizing. Available in fractional Fractional sizes, it offers versatility and precision for professional metalworking and industrial applications.
