The Carmex Threading Tap is a spiral-flute UNF Supercut tap designed for professionals who need precise, dependable threading in challenging materials. It’s built for 7/16" diameter, 20 TPI UNF applications, delivering clean threads with durable, heat-resistant performance.

• Material: HSS-E (high-speed steel with cobalt) for enhanced wear resistance and elevated heat tolerance during operation.
• Flute Design: Spiral flute aids rapid chip evacuation, reducing clogging and promoting smooth cutting in hard or gummy materials.
• Thread Type: UNF (Unified National Fine) threading to achieve accurate, tight-fit threads on 7/16" diameter fasteners.
• Size & Pitch: 7/16" diameter with 20 threads per inch (7/16 x 20 UNF) for precise, fine-threaded results.
• Cutting Geometry: Supercut design focused on delivering a clean thread form with consistent tooling action and extended life.

With its HSS-E alloy and optimized spiral geometry, this tap excels in demanding metals and high-speed threading tasks, delivering reliable threads where precision matters most. The combination of cobalt-enhanced tooling and efficient chip removal helps reduce heat buildup, extend tool life, and improve overall throughput. Whether you're building, repairing, or fabricating components that require UNF 7/16‑20 threads, this Carmex tap provides a trustworthy, long-lasting solution that supports accurate, repeatable results.
