Norseman Drill & Tool Type 29-ALN HSS Titanium Aluminum Nitride High Performance Reduced Neck Spiral Point Taps

Norseman Drill & Tool Type 29-ALN HSS Titanium Aluminum Nitride Reduced Neck Spiral Point Taps

Extreme Performance for High-Temperature and Hardened Materials

The Norseman Drill & Tool Type 29-ALN HSS Titanium Aluminum Nitride High Performance Reduced Neck Spiral Point Tap is engineered for aggressive machining environments where heat, hardness, and tool life are critical concerns. Built for precision and durability, this premium tap delivers consistent, high-quality threads in some of the most challenging materials encountered in industrial production.

Reduced Neck Geometry for Lower Torque

Cooler Cutting and Improved Stability

The reduced neck design minimizes contact between the tap body and the workpiece, significantly reducing friction and cutting torque. This geometry allows the tap to run cooler at higher speeds, improves chip flow, and reduces the risk of tap breakage. The result is enhanced accuracy, better thread quality, and improved performance in continuous-duty machining operations.

Spiral Point Design for Efficient Chip Control

Optimized for Through-Hole Applications

Featuring a spiral point (gun tap) geometry, the Type 29-ALN efficiently pushes chips forward and out of the hole. This prevents chip packing and recutting, making it ideal for through-hole threading and high-production environments where uninterrupted cutting is essential.

Titanium Aluminum Nitride (TiAlN) Coating

Built for Heat and Hardness

The Titanium Aluminum Nitride (TiAlN) coating provides extreme surface hardness and exceptional thermal stability. Unlike traditional coatings, TiAlN excels in high-temperature operations, forming a protective oxide layer that resists wear and oxidation. This makes it especially effective for hardened steels and cast iron up to 45 Rockwell C, where conventional taps struggle.

Designed for Difficult-to-Machine Materials

Reliable Performance Under Extreme Conditions

The Type 29-ALN is purpose-built for threading hardened steels, alloy steels, and cast iron, delivering long tool life and consistent results in demanding CNC and production environments. Its toughness and heat resistance make it ideal for dry or reduced-lubrication machining applications.
