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

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

High-Performance TiCN Coated Taps for Demanding Threading Applications

The Norseman Drill & Tool Type 29-ACN Machine Screw HSS Reduced Neck Spiral Point Tap is engineered for high-productivity threading in tough, abrasive, and high-alloy materials. Designed with advanced geometry and finished with a Titanium Carbon Nitride (TiCN) coating, this tap delivers exceptional tool life, reduced torque, and consistent thread quality in demanding production environments.

Reduced Neck Geometry for Improved Performance

Lower Torque, Cooler Cutting, Longer Tool Life

The high-performance reduced neck design minimizes friction between the tap body and the workpiece, allowing the cutting edges to engage more efficiently. This geometry reduces torque, improves chip evacuation, and helps the tool run cooler—critical advantages when threading hard or gummy materials. The result is greater accuracy, less breakage, and improved performance in CNC and automated machining operations.

Spiral Point Design for Clean, Efficient Threading

Ideal for Machine Screw Through-Hole Applications

The spiral point (gun tap) configuration pushes chips forward and out of the hole, preventing chip packing and reducing downtime caused by broken taps. This makes the Type 29-ACN especially effective for machine screw through-hole threading, producing clean, consistent threads at higher speeds and feed rates.

Titanium Carbon Nitride Coating for High Productivity

Engineered for Stainless Steel, Nickel & Aluminum

The Titanium Carbon Nitride (TiCN) coating provides a harder surface than traditional TiN coatings, dramatically increasing wear resistance and edge strength. TiCN excels in stainless steel, nickel alloys, aluminum, and mixed-material applications, delivering longer tool life and superior performance across multiple materials. Its enhanced lubricity reduces friction, improves surface finish, and supports higher production output.

Premium HSS Construction for Versatile Applications

Manufactured from high-quality High-Speed Steel (HSS), Norseman Type 29-ACN taps combine toughness with precision, making them suitable for a wide range of industrial threading tasks.
