Norseman Drill & Tool Type 29-AG Fractional HSS Gold Oxide High Performance Reduced Neck Spiral Point Taps

Norseman Drill & Tool Type 29-AG Fractional HSS Reduced Neck Spiral Point Taps

Gold Oxide Performance for High-Efficiency Threading

The Norseman Drill & Tool Type 29-AG Fractional HSS Gold Oxide High Performance Reduced Neck Spiral Point Tap is engineered for precision, durability, and speed in demanding machining environments. Designed specifically for fractional thread sizes, this premium tap delivers smooth, accurate threads with reduced torque and extended tool life—making it a trusted choice for production machining, maintenance, and repair operations.

Reduced Neck Geometry for Lower Torque

Cooler Cutting and Improved Stability

The reduced neck design minimizes body contact with the workpiece, significantly lowering friction during threading. This geometry allows the tap to run cooler, improves chip flow, and reduces the risk of tap breakage—especially in higher-speed or automated applications. Improved stability also promotes straighter threads and consistent dimensional accuracy.

Spiral Point Design for Forward Chip Evacuation

Ideal for Through-Hole Applications

Featuring a spiral point (gun tap) configuration, the Type 29-AG pushes chips forward and out of the hole, preventing chip packing and recutting. This makes it especially effective for through-hole tapping, where uninterrupted chip evacuation is essential for clean threads and reliable performance.

Gold Oxide Finish for Enhanced Lubricity

Toughness and Wear Resistance

The Gold Oxide surface treatment provides low-temperature stress relief that enhances lubricity and reduces cutting friction. This finish increases tap toughness, improves wear resistance, and promotes smoother cutting action, resulting in better thread quality and longer tool life compared to uncoated taps.

Built from High-Speed Steel for Versatile Performance

Precision You Can Depend On

Manufactured from premium HSS (High-Speed Steel), these fractional spiral point taps are suitable for threading carbon steel, alloy steel, cast iron, and select non-ferrous materials. Their balance of strength and flexibility makes them ideal for CNC machining, production runs, and general shop use.
