Learn more about Klarna
Description
The Carmex Threading Tap with Spiral Flute is built for precise UNC threading in demanding materials. Designed for machinists and fabricators who demand reliability, it delivers clean, consistent threads with long-lasting performance.
- Thread size & type: 7/16" diameter, 14 threads per inch (UNC) for Unified National Coarse projects.
- Flute design: Spiral flute enables efficient chip evacuation and reduces the risk of clogging during cutting.
- Material: HSS-E (high-speed steel with cobalt) for enhanced hardness and heat resistance in tough materials.
- Geometry: UNC Supercut tapping geometry crafted for smoother cutting action and a reliable thread finish.
- Applications: Optimized for high-speed threading operations in challenging materials where durability matters.
With this tap, you get precise, repeatable threads and longer tool life even in demanding manufacturing environments. The spiral flute design keeps chips moving away from the cutting edge, helping maintain steady cutting forces and reducing rework, while the cobalt-infused HSS ensures sharpness and heat resistance throughout production runs.
