Norseman Drill & Tool Type 39 Metric 52º Helix Angle Bright Finish Spiral Flute Semi-Bottoming Taps
Norseman Drill & Tool Type 39 Metric Spiral Flute Taps
Precision 52º Helix Angle for Superior Chip Control
The Norseman Drill & Tool Type 39 Metric 52º Helix Angle Bright Finish Spiral Flute Semi-Bottoming Taps are engineered to deliver exceptional threading performance in deep, blind, or hard-to-reach holes. Featuring an aggressive 52º helix angle, these taps provide fast, efficient chip evacuation by pulling chips upward and out of the cutting zone. This advanced flute geometry reduces clogging, minimizes heat buildup, and ensures clean, accurate threads with every pass. Their semi-bottoming design allows them to be used for both plug and bottoming applications, offering versatility across machining environments.
Bright Finish for Clean, Consistent Threading
Smooth Cutting Action on Soft, Ductile Materials
The Type 39 Bright Finish taps are specifically optimized for materials such as aluminum, brass, copper, and other soft or ductile metals. The bright, uncoated finish provides a smooth cutting surface that reduces friction and improves chip flow while maintaining precise edge sharpness. This makes them ideal for threading operations that require clean finishes, minimal burr formation, and reliable dimensional accuracy.
Optimized for Deep and Blind Hole Tapping
Enhanced Control and High-Quality Results
With their 52º spiral flute design, these taps excel in deep hole applications where chip removal is critical to maintaining thread quality. The semi-bottoming configuration allows operators to cut threads closer to the bottom of blind holes than traditional plug taps can achieve. This capability is especially valuable in precision parts manufacturing, maintenance, repair operations, and CNC machining.
Built for Professional Performance
Manufactured to Norseman’s demanding quality standards, the Type 39 Bright Finish Spiral Flute Taps deliver durability, accuracy, and long-lasting performance. Whether used in manual setups or automated machining centers, they provide reliable chip control and top-tier thread quality.
For machinists seeking high-performance metric taps for soft materials, Norseman Type 39 Bright Finish taps offer exceptional value, precision, and dependability.
