Norseman Drill & Tool Type 190-PT Titanium Nitride Parabolic Flute Twist Drill Bit
Norseman Drill & Tool Type 190-PT TiN Parabolic Flute Twist Drill Bit
Maximum Tool Life, Minimal Downtime
For professionals who demand extreme durability and high-efficiency drilling, the Norseman Drill & Tool Type 190-PT Titanium Nitride (TiN) Parabolic Flute Twist Drill Bit delivers incomparable performance. Proudly made in the USA, this premium bit is engineered to excel in abrasive, high-load drilling environments where inferior tools quickly fail.
TiN Coating for Exceptional Longevity
Extend Tool Life by 500% or More
The defining feature of the 190-PT is its Titanium Nitride (TiN) coating—a super-hard, wear-resistant surface treatment that dramatically extends tool life. TiN reduces friction, lowers heat buildup, and allows higher cutting speeds, giving you consistent performance even when drilling hardened steels, cast iron, and other demanding materials.
Parabolic Flute Geometry
Deep-Hole Drilling Without Interruption
The parabolic flute design enables high-volume chip evacuation during deep-hole drilling. This prevents clogging, reduces heat, and eliminates the need for frequent drill retractions. The result is smoother drilling, faster cycle times, and less downtime—making it ideal for production environments and heavy-duty maintenance work.
135° Split Point
Fast, Accurate, Walk-Free Starts
Equipped with a 135° split point, the 190-PT offers immediate cutting action with no walking or wandering. It penetrates cleanly without a pilot hole, improving accuracy and efficiency in both manual and machine drilling applications.
