Norseman Drill & Tool Wire Gauge Sizes Type 190-PT Twist Drill Bit
Precision Meets Maximum Performance
The Norseman Drill & Tool Wire Gauge Sizes Type 190-PT Twist Drill Bit is engineered for professionals who require ultra-precise hole sizing, exceptional durability, and top-tier performance in deep-hole drilling applications. Made in the USA from premium high-speed steel (HSS), this advanced drill bit features a Titanium Nitride (TiN) coating that boosts wear resistance and extends tool life by 500% or more, even in abrasive or high-volume production environments.
Built for Deep-Hole Efficiency and Precision
The Type 190-PT’s parabolic flute design is optimized for fast, efficient chip evacuation—an essential feature for deep-hole drilling in metals, plastics, and composites. This geometry reduces friction, minimizes heat buildup, and decreases the need for frequent chip clearing, resulting in faster drilling cycles and improved tool longevity.
Wire gauge sizing provides fine incremental drilling options that are ideal for precision machining, electronics assembly, aerospace components, and mechanical fittings. Each bit delivers a perfect balance of strength and accuracy, ensuring consistent results where exact hole diameters are critical.
The 135° split-point tip guarantees fast, walk-free starts with no pilot hole required. By reducing thrust pressure and eliminating walking, this design enhances drilling accuracy and significantly improves overall drilling efficiency.
