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

Norseman Drill & Tool Type 29-ACN Metric Reduced Neck Spiral Point Taps

High-Productivity TiCN Performance for Precision Metric Threading

The Norseman Drill & Tool Type 29-ACN Metric HSS Reduced Neck Spiral Point Tap is engineered for high-output threading in demanding industrial and production environments. Designed for metric thread applications, this tap combines advanced cutting geometry with a Titanium Carbon Nitride (TiCN) coating to deliver exceptional tool life, reduced torque, and superior performance across multiple materials.

Reduced Neck Geometry for Cooler, More Efficient Cutting

Lower Torque and Improved Thread Quality

The high-performance reduced neck design minimizes surface contact between the tap body and the workpiece. This reduces friction, lowers torque requirements, and allows the tool to run cooler—especially important when threading tougher materials. The result is improved dimensional accuracy, smoother thread finishes, and a lower risk of tap breakage during high-speed or continuous operations.

Spiral Point Design for Forward Chip Evacuation

Ideal for Metric Through-Hole Applications

Featuring a spiral point (gun tap) geometry, the Type 29-ACN drives chips forward and out of the hole during cutting. This prevents chip packing in the flutes and cutting edges, making it ideal for through-hole metric threading. The design supports faster feed rates, increased productivity, and consistent performance in CNC and manual machining environments.

Titanium Carbon Nitride (TiCN) Coating

Built for Stainless Steel, Nickel & Aluminum

The TiCN coating provides a significantly harder surface than traditional TiN finishes, delivering outstanding abrasion resistance and edge strength. Its enhanced lubricity reduces friction and heat buildup, enabling high-productivity threading in stainless steel, nickel alloys, aluminum, and mixed-material applications. This makes the Type 29-ACN a versatile solution for shops running diverse materials.

Premium HSS Construction for Industrial Reliability

Manufactured from high-quality High-Speed Steel (HSS), these metric taps offer the toughness and durability required for production machining, maintenance, and repair operations where reliability is critical.
