Norseman Type 20-AGN Fractional Spiral Point Taps
High-Performance Tapping with Titanium Nitride Coating
The Norseman Drill & Tool Type 20-AGN Fractional Spiral Point Tap is a premium threading tool designed for professionals who demand precision, durability, and productivity. Made in the USA from high-speed steel (HSS) and finished with a Titanium Nitride (TiN) coating, this tap is built for long-lasting performance in demanding environments.
Engineered for through-hole applications, the 20-AGN tap is ideal for use in CNC machines, drill presses, or manual tapping in materials such as mild steel, stainless steel, alloy steels, and cast iron.
Spiral Point Geometry for Fast, Clean Threads
Optimized for Chip Ejection and Efficiency
The spiral point design directs chips forward, out of the hole, preventing clogging and minimizing breakage. This feature makes the 20-AGN tap an excellent choice for high-speed tapping operations in production settings.
-
Ideal for through-holes in tough materials
-
Promotes chip flow away from the cutting edge
-
Reduces torque and improves tool control
Titanium Nitride Coating for Maximum Tool Life
Exceptional Surface Hardness and Lubricity
The Titanium Nitride (TiN) coating significantly enhances tool performance by increasing surface hardness and reducing friction during cutting.
-
Higher wear resistance for extended tool life
-
Superior lubricity decreases heat buildup
-
Excellent for abrasive or hard materials
This coating ensures longer-lasting taps with consistent thread quality, even in high-volume production.
