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

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

High-Productivity TiCN Performance for Demanding Materials

The Norseman Drill & Tool Type 29-ACN Fractional HSS Reduced Neck Spiral Point Tap is engineered for high-performance threading in demanding production and maintenance environments. Designed with advanced geometry and enhanced by a Titanium Carbon Nitride (TiCN) coating, this tap delivers exceptional wear resistance, reduced torque, and long tool life when threading challenging materials such as stainless steel, nickel alloys, and aluminum.

High-Performance Reduced Neck Design

Lower Torque, Cooler Operation, Greater Accuracy

The reduced neck geometry minimizes contact between the tap body and the workpiece, significantly reducing friction during cutting. This design lowers torque requirements, improves chip control, and allows the tap to run cooler—key advantages when working with hard or heat-generating materials. The result is improved thread accuracy, reduced risk of tap breakage, and consistent performance in both CNC and conventional machining operations.

Spiral Point Geometry for Efficient Chip Flow

Ideal for Fractional Through-Hole Threading

The spiral point (gun tap) design forces chips forward and out of the hole, preventing chip buildup in the cutting zone. This makes the Type 29-ACN especially effective for fractional through-hole applications, enabling higher speeds, cleaner threads, and increased productivity compared to conventional hand taps.

Titanium Carbon Nitride Coating for Extended Tool Life

Built for Stainless Steel, Nickel & Aluminum

The TiCN coating is harder than standard TiN finishes, providing superior abrasion resistance and edge strength. This advanced coating enhances lubricity, reduces friction, and supports high-speed threading in stainless steel, nickel-based alloys, aluminum, and mixed-material applications. TiCN-coated taps are ideal for shops seeking high productivity and versatility across multiple materials.

Premium HSS Construction for Versatile Applications

Manufactured from high-quality High-Speed Steel (HSS), Norseman Type 29-ACN taps combine toughness and precision, making them a dependable choice for production machining, maintenance, and industrial repair work.
