Norseman Drill & Tool Wire Gauge Sizes Type 190-PT Twist Drill Bit
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 demand pinpoint precision, long tool life, and efficient deep-hole drilling. Built in the USA from premium high-speed steel (HSS), this heavy-duty drill bit features a Titanium Nitride (TiN) coating, extending tool life by 500% or more in abrasive and high-volume applications.
Its parabolic flute design is optimized for deep-hole drilling, allowing for fast, efficient chip removal and reducing the need for drill retraction. This not only improves cutting performance but also minimizes heat buildup—especially important when working with tough materials like stainless steel, titanium alloys, or hardened tool steels.
The wire gauge sizing provides ultra-fine incremental options, perfect for applications requiring exact hole diameters, such as electrical work, mechanical assemblies, and precision machining. Combined with a 135° split point, this drill bit offers quick, accurate starts with no walking—eliminating the need for pilot holes and reducing overall cycle time.
