Norseman Drill and Tool Type 20-AG Fractional HSS Spiral Point Plug Taps
Norseman Type 20-AG Fractional HSS Spiral Point Taps
Precision Tapping with Enhanced Durability and Performance
The Norseman Drill & Tool Type 20-AG Fractional Spiral Point Tap is engineered for high-performance threading in demanding industrial and machining environments. Manufactured from premium high-speed steel (HSS) and finished with a gold oxide coating, this tap is designed to cut clean, accurate threads in a wide range of metals, including carbon steel, stainless steel, and alloy steels.
Ideal for through-hole tapping, the 20-AG spiral point tap is widely used in manual, CNC, and production tapping operations where speed, accuracy, and tool longevity are critical.
Spiral Point Design for Efficient Chip Control
Optimized for Through-Hole Applications
The spiral point geometry of the 20-AG tap drives chips ahead of the cutting action, clearing the hole during threading. This feature minimizes chip packing, prevents tap breakage, and allows for uninterrupted threading—making it the go-to solution for high-speed, high-volume production.
-
Ideal for through-holes in ferrous metals
-
Excellent chip evacuation for smooth operation
-
Reduces tap wear and breakage
Gold Oxide Finish for Superior Tool Life
Reduced Friction, Increased Toughness
The gold oxide finish on Norseman’s Type 20-AG taps provides a critical performance edge:
-
Low-temperature stress relief improves tap toughness
-
Enhanced lubricity reduces cutting friction
-
Prolongs tap life and improves thread quality
This coating also helps the tap retain cutting fluids, further enhancing its performance in tough materials.
