Norseman Drill & Tool Letter Sizes Type 190-PT Twist Drill Bit
Norseman Drill & Tool Letter Sizes Type 190-PT Twist Drill Bit: High-Performance Drilling with Titanium Nitride Edge
The Norseman Drill & Tool Letter Sizes Type 190-PT Twist Drill Bit delivers the cutting-edge performance professionals need in high-demand applications. Engineered with a Titanium Nitride (TiN) coating, this drill bit offers up to 500% longer tool life, making it an ideal solution for abrasive materials and high-volume drilling environments.
Crafted in the USA from industrial-grade high-speed steel (HSS), the 190-PT is built to withstand intense heat and pressure. Its parabolic flute design ensures optimal chip evacuation during deep-hole drilling, reducing friction, improving cutting speed, and minimizing the need for frequent drill retraction. This means more efficiency and less downtime on the job.
The letter sizing makes it ideal for applications requiring precise non-fractional hole diameters—commonly used in aerospace, automotive, and general engineering projects. A 135° split point ensures fast, accurate starts without wandering, eliminating the need for pilot holes and improving hole quality from the first cut.
