Norseman Drill & Tool Wire Sizes HSS Heavy-Duty NAS 907B Type 190-ACN Titanium Carbon Nitride Jobber Length Twist Bit

Norseman Drill & Tool Wire Gauge Sizes HSS Heavy-Duty NAS 907B Type 190-ACN Jobber Length Twist Bit: TiCN-Coated Precision for Maximum Durability and Performance

The Norseman Drill & Tool Wire Gauge Sizes HSS Heavy-Duty NAS 907B Type 190-ACN Jobber Length Twist Bit delivers exceptional drilling performance, strength, and tool life for professionals who demand precision in every application. Proudly made in the USA, this heavy-duty bit is manufactured to NAS 907B aerospace-grade specifications, ensuring consistency, accuracy, and reliability for industrial, fabrication, and maintenance work.

Constructed from premium high-speed steel (HSS), the Type 190-ACN is built to handle tough materials such as stainless steel, titanium, and high-tensile alloys. Its 135° self-centering split point provides fast starts, reduced thrust, and prevents walking—producing cleaner, more precise holes while extending cutting edge life.

The advanced Titanium Carbon Nitride (TiCN) coating enhances hardness, lubricity, and heat resistance, making this bit ideal for high-speed or heavy-duty applications. TiCN’s ultra-smooth surface reduces friction, improves chip flow, and allows for cooler, more efficient drilling. This coating also increases wear resistance, significantly extending tool life and maintaining superior performance under extreme drilling conditions.

Each bit is precision-ground to tight aerospace tolerances for excellent balance, accuracy, and repeatability. Available in wire gauge sizes, these bits provide precise incremental sizing ideal for fine-tolerance work in aerospace, manufacturing, and precision engineering environments.
