Norseman Drill & Tool HSS Heavy-Duty NAS 907B Type 190-ACN Jobber Length Twist Bit

Norseman Drill & Tool HSS Heavy-Duty NAS 907B Type 190-ACN Jobber Length Twist Bit: TiCN-Coated Strength for Superior Wear Resistance and Precision

The Norseman Drill & Tool HSS Heavy-Duty NAS 907B Type 190-ACN Jobber Length Twist Bit is engineered for maximum strength, precision, and tool life in demanding industrial applications. Proudly made in the USA, this high-performance drill bit is manufactured to NAS 907B aerospace-grade specifications, guaranteeing exceptional accuracy, durability, and consistency on every job.

Crafted from premium high-speed steel (HSS), the Type 190-ACN is designed to withstand the rigors of drilling through tough materials such as stainless steel, titanium, and hardened alloys. Its heavy-duty construction provides superior rigidity and cutting strength, while the 135° self-centering split point ensures fast, accurate starts without walking—reducing thrust and improving hole precision.

What truly sets this bit apart is its Titanium Carbon Nitride (TiCN) coating, a state-of-the-art finish that dramatically enhances hardness, lubricity, and heat resistance. The TiCN coating provides a smoother cutting surface for efficient chip evacuation and minimizes friction, allowing for higher cutting speeds and cooler operation. It also extends tool life significantly, even under continuous or high-temperature drilling conditions.

Each bit is precision-ground to exact aerospace tolerances for balanced, vibration-free operation and superior finish quality. The Type 190-ACN is the ideal choice for machinists, fabricators, and maintenance professionals seeking dependable, long-lasting performance.
