Norseman Drill & Tool Magnum Super Premium NAS 907B Type 190-SS Jobber Length Fractional Twist Bit
High-Helix Power for Non-Ferrous and Stainless Applications
The Norseman Drill & Tool Magnum Super Premium NAS 907B Type 190-SS Jobber Length Fractional Twist Bit is engineered for exceptional cutting speed, accuracy, and durability. Proudly Made in the USA, this high-performance drill bit is manufactured to NAS 907B aerospace standards, delivering the consistency, strength, and precision demanded by today’s industrial professionals.
High Helix Design for Faster Cutting
Featuring an advanced High Helix Flute geometry, the 190-SS is optimized for increased feed rates and superior chip evacuation. This high-helix design greatly reduces heat buildup and friction while promoting cleaner, more efficient cutting—making it the ideal choice for:
-
Stainless steel
-
Aluminum
-
Brass
-
Bronze
-
All non-ferrous metals
With improved chip flow and reduced loading, this drill bit maintains exceptional performance in both high-speed and continuous drilling environments.
Precision Starts with a 135° Split Point
Equipped with a 135° self-centering split point, the 190-SS delivers fast, accurate penetration without requiring a center punch. This reduces walking, lowers thrust pressure, and ensures clean, precise hole formation even on curved or hard surfaces.
Magnum Super Premium Strength
Manufactured from high-molybdenum tool steel, this bit retains sharpness and structural integrity even at elevated drilling temperatures. The black and gold oxide finish enhances lubricity, improves corrosion resistance, and supports cooler operation—all contributing to significantly extended tool life.
