Norseman Drill & Tool Type 39-ACN Metric 52º Helix Angle Titanium Carbon Nitride Spiral Flute Semi-Bottoming Taps
Norseman Drill & Tool Type 39-ACN Metric Spiral Flute Taps
High-Performance 52º Helix Angle Titanium Carbon Nitride Taps
The Norseman Drill & Tool Type 39-ACN Metric 52º Helix Angle Spiral Flute Semi-Bottoming Taps are engineered for exceptional performance in precision threading applications. Designed with a steep 52º helix angle, these taps provide superior chip evacuation and are ideal for tapping deep or blind holes where chip removal is critical. Their geometry allows them to function effectively as both plug and bottoming taps, making them a versatile solution for a broad range of machining tasks.
Advanced TiCN Coating for Superior Wear Resistance
Increased Hardness and Extended Tool Life
Each Type 39-ACN tap features a Titanium Carbon Nitride (TiCN) coating that significantly increases surface hardness, enhances lubricity, and reduces friction during operation. This advanced coating improves tool longevity, strengthens cutting edges, and enables higher cutting speeds—delivering consistent, accurate threads even in demanding production environments. TiCN also greatly improves resistance to abrasion, making these taps ideal for applications requiring durability and precision.
Optimized for Soft Ductile Materials
Clean, Accurate Threads in Deep or Blind Holes
Engineered specifically for materials such as aluminum, brass, copper, and other soft ductile metals, the Type 39-ACN tap excels where smooth cutting action and superior chip control are required. The aggressive 52º spiral flute design efficiently lifts chips out of the hole, preventing clogging and ensuring high-quality thread finish. This makes the tap particularly effective for deep hole threading and applications where threads must extend close to the bottom of blind holes.
Built for Precision Machining
Manufactured to Norseman’s exacting standards, these metric semi-bottoming taps provide exceptional accuracy, long service life, and reliable performance across production, maintenance, and industrial machining environments.
For shops seeking premium-quality metric taps with advanced coating technology and superior chip evacuation, Norseman’s Type 39-ACN delivers unmatched efficiency and durability.
