Norseman Drill & Tool Wire Gauge Sizes Type 190-P Twist Drill Bit
Norseman Drill & Tool Wire Gauge Sizes Type 190-P Twist Drill Bit
Precision Deep-Hole Drilling You Can Rely On
The Norseman Drill & Tool Wire Gauge Sizes Type 190-P Twist Drill Bit is engineered for professionals who require extreme precision, superior chip control, and dependable performance in deep-hole drilling applications. Proudly made in the USA from premium high-speed steel (HSS), this drill bit’s advanced parabolic flute design delivers exceptional chip evacuation, reduced heat buildup, and cleaner drilling through metal, wood, plastics, and composite materials.
Precision Sizing for Technical Applications
Wire gauge sizing provides fine incremental measurement control, making this drill bit ideal for applications where standard fractional or metric options are too coarse. Machinists, toolmakers, electronics technicians, and aerospace professionals rely on wire gauge bits for exact hole diameters, repeatability, and tolerance-critical work.
The 135° split point ensures fast, accurate, walk-free starts without requiring a pilot hole. This improves efficiency, reduces workpiece damage, and enhances accuracy—especially beneficial when drilling deep or into curved or hardened surfaces.
Built for Durability, Control, and Cool Cutting
A black and gold oxide finish adds lubricity, reduces friction, and increases wear resistance, extending tool life even under high-speed drilling conditions. The finish also promotes smoother chip flow, further enhancing the parabolic flute’s ability to remove material efficiently during deep drilling operations.
