Norseman Drill & Tool Fractional Sizes Type 190-PT Twist Drill Bit
Premium Power with Titanium Nitride Performance
The Norseman Drill & Tool Fractional Sizes Type 190-PT Twist Drill Bit is engineered for professionals who demand exceptional durability, cutting efficiency, and precision during high-performance drilling. Manufactured in the USA from premium high-speed steel (HSS), this advanced drill bit features a Titanium Nitride (TiN) coating that delivers up to 500% longer tool life, making it ideal for abrasive materials, high-production shops, and continuous drilling operations.
Engineered for Deep-Hole Drilling Efficiency
Designed with a parabolic flute geometry, the Type 190-PT excels in deep-hole drilling by improving chip evacuation and minimizing heat buildup. This reduces the need for frequent bit withdrawal, allowing smoother, faster drilling and boosting overall productivity. Whether used in fabrication, metalworking, or heavy-duty industrial maintenance, this design ensures consistent performance in challenging applications.
The fractional sizing provides compatibility with standard U.S. hole dimensions, making it the perfect choice for machinists, contractors, and manufacturing professionals who need exact measurements and repeatable accuracy. The 135° split point tip ensures clean, walk-free starts, reduces thrust requirements, and enhances drilling precision on hard, curved, or uneven surfaces.
