Learn more about Klarna
Description
The Carmex Spiral Point UNF Supercut Tap is a precision threading tool designed for Unified National Fine (UNF) threads. Built with durable powder metal and a spiral point geometry, it delivers reliable, fast threading in challenging materials.
- Tap type: Spiral Point design that directs chips forward and minimizes clogging, enabling smoother, faster threading.
- Thread specification: UNF (Unified National Fine) threads, 7/16-20 size (7/16" diameter, 20 TPI).
- Cutting geometry: Supercut design for efficient material removal and clean, accurate threads.
- Material: Powder Metal construction for durability and wear resistance in demanding operations.
- Applications: Optimized for high-speed threading and reliable performance on tough materials requiring precise UNF threads.
This tap helps machinists achieve consistent thread quality with reduced downtime. The spiral point pushes chips ahead of the flute, contributing to smoother tool operation and fewer interruptions during production. Use with proper cutting fluids and tapping techniques to maximize tool life and maintain accurate thread fit across UNF projects.
