Norseman Drill & Tool Type 37-AGN Fractional 52º Helix Angle Titanium Nitride Spiral Flute Semi-Bottoming Taps

Norseman Drill & Tool Type 37-AGN Fractional 52º Helix Angle Titanium Nitride Spiral Flute Semi-Bottoming Taps

Norseman Drill & Tool Type 37-AGN Fractional Spiral Flute Semi-Bottoming Taps are engineered for high-performance threading in deep holes and soft, ductile materials. With a steep 52º helix angle and a premium Titanium Nitride (TiN) coating, these taps deliver exceptional chip control, long tool life, and superior thread finish—making them an ideal choice for precision machining and demanding production environments.

Titanium Nitride Coating for Extended Tool Life

The TiN coating significantly enhances surface hardness and lubricity, reducing friction and heat generation during tapping. This improvement in wear resistance helps maintain sharp cutting edges, improves overall tapping efficiency, and extends tool life. Machinists benefit from cleaner threads, smoother operation, and reduced downtime for tool changes.

52º Helix Angle for Superior Chip Evacuation

Ideal for Deep Holes and Soft, Ductile Materials

The aggressive 52º helix angle provides rapid and efficient chip lifting, preventing jamming, chip packing, or tool breakage—especially in deep-hole applications. This makes Type 37-AGN taps highly effective in materials like aluminum, copper, brass, and other soft metals where long, stringy chips can cause problems.

Semi-Bottoming Geometry for Precision Threading

Excellent for Blind Hole Applications

Semi-bottoming taps allow threading close to the bottom of blind holes while maintaining easier starting action than a full bottoming tap. The result is precise, well-formed threads that meet tight tolerances in critical applications.

Key Benefits

• TiN coating adds lubricity and hardness for improved tool life

• 52º helix angle provides superior chip evacuation

• Ideal for deep blind or through holes in soft, ductile metals

• Spiral flute geometry enhances thread quality and reduces torque

• Fractional sizing ensures compatibility with standard tooling

For machinists seeking accuracy, efficiency, and durability, Norseman Type 37-AGN taps deliver top-tier performance and reliable results in demanding threading applications.
