Norseman Drill & Tool Wire Sizes HD Super Premium NAS 907B Type 190-AG Jobber Length Twist Bit
Norseman Drill & Tool Wire Sizes HD Super Premium NAS 907B Type 190-AG Jobber Length Twist Bit: Unmatched Precision and Durability in Every Size
The Norseman Drill & Tool Wire Sizes HD Super Premium NAS 907B Type 190-AG Jobber Length Twist Bit represents the pinnacle of American-made quality, engineered for maximum performance, precision, and tool life. Part of Norseman’s Magnum Super Premium Series, this bit is designed to outperform cobalt drills in tough, work-hardening materials such as stainless steel, titanium, and high-tensile alloys.
Crafted from high-molybdenum tool steel, each bit is enhanced with a specialized nitro-carburized surface treatment that improves hardness, lubricity, and wear resistance. This process ensures smoother drilling, less heat buildup, and extended tool life—even under continuous, high-speed operation.
The low-temperature stress relief process used in Norseman’s manufacturing further increases the bit’s toughness while minimizing brittleness. Combined with a 135° split point, these bits provide accurate starts, reduced walking, and lower feed pressure—ideal for precision drilling in metal fabrication, aerospace, and maintenance applications.
Complying with NAS 907B aerospace standards, the Type 190-AG Jobber Length Twist Bit is precision-ground for superior balance and accurate hole geometry. Its black and gold oxide finish enhances chip flow, corrosion resistance, and cutting efficiency, making it perfect for high-demand production and repair work.
Available in wire gauge sizes, these bits offer fine incremental options for precision hole sizing in critical manufacturing and assembly operations.
