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 precision-engineered for maximum cutting speed, accuracy, and durability. Designed for professionals who demand exceptional performance, this American-made drill bit meets NAS 907B aerospace standards, ensuring the highest level of consistency and quality.

Featuring a High Helix Flute design, the 190-SS allows for increased feed rates and efficient chip removal, improving cutting performance and reducing heat buildup during drilling. This makes it ideal for machining stainless steel, aluminum, brass, and all other non-ferrous metals, providing cleaner holes and smoother finishes.

The 135° split-point tip delivers fast, accurate penetration without the need for a center punch. This design minimizes walking, reduces thrust pressure, and improves control—perfect for high-precision drilling on curved or hard surfaces. Combined with the bit’s high-helix geometry, it ensures faster cutting and longer tool life under continuous or high-speed use.

Manufactured from high-molybdenum tool steel, each Magnum Super Premium bit maintains exceptional sharpness and strength, even at elevated drilling temperatures. The black and gold oxide finish enhances lubricity, resists corrosion, and supports cooler operation during demanding drilling conditions.

Available in fractional inch sizes, the 190-SS provides unmatched versatility for industrial, fabrication, and maintenance applications where precision and productivity matter most.
