Norseman Drill & Tool Type 39-AGN Metric 52º Helix Angle Titanium Nitride Spiral Flute Semi-Bottoming Taps
Norseman Drill & Tool Type 39-AGN Metric Spiral Flute Taps
Precision 52º Helix Angle for Superior Chip Control
The Norseman Drill & Tool Type 39-AGN Metric 52º Helix Angle Spiral Flute Semi-Bottoming Taps are engineered for high-efficiency threading in deep, blind, or hard-to-reach holes. Featuring an aggressive 52º helix angle, these taps offer exceptional chip evacuation, pulling chips up and out of the hole to prevent clogging and ensure smooth, accurate thread formation. Their geometry allows them to function as both plug and bottoming taps, delivering versatility across a wide range of machining applications.
Titanium Nitride Coating for Enhanced Performance
Increased Lubricity, Hardness, and Tool Life
Each Type 39-AGN tap is coated with Titanium Nitride (TiN), a premium coating known for its excellent lubricity and increased surface hardness. This coating reduces friction during cutting, improves wear resistance, and helps maintain sharper cutting edges over extended use. The TiN finish also supports higher operating speeds and cleaner thread quality, making these taps ideal for both manual and CNC applications.
Optimized for Soft, Ductile Metals
Ideal for Aluminum, Brass, Copper & Deep Hole Applications
This tap series is specifically recommended for machining soft ductile materials such as aluminum, copper, and brass. The high helix spiral flute design efficiently lifts chips away from the cutting zone, preventing chip packing and allowing for precise threading even in deep or blind holes. The semi-bottoming configuration also makes it possible to thread closer to the bottom of holes compared to standard plug taps, enhancing versatility and thread accuracy.
Built for Professional Machining Environments
Manufactured to Norseman’s rigorous quality standards, the Type 39-AGN Metric Spiral Flute Taps offer exceptional durability, reliable thread integrity, and consistent performance across production, maintenance, and industrial machining operations.
For shops needing high-performance metric taps with advanced coating and superior chip evacuation, Norseman Type 39-AGN delivers proven results and long-lasting value.
