Description

The Carmex Spiral Point UNF Supercut Tap (3/8 x 24) is a precision threading tool designed for UNF applications in demanding materials. Built for professionals who need reliable, fast tapping with long tool life, it delivers clean threads and consistent performance.

  • Thread Size and Type: 3/8 x 24 UNF threading for fine, high-precision threads.
  • Material: HSS-E (high-speed steel with cobalt content) for enhanced wear resistance and heat tolerance.
  • Design: Spiral Point geometry directs chips forward and reduces clogging, enabling smoother starts and faster cutting.
  • Specialty: UNF Supercut geometry engineered for precise, durable threads in tough materials.
  • Application Focus: Optimized for high-speed threading operations where strong, accurate UNF threads are required.

Designed to deliver reliable, repeatable results, this tap minimizes chip-related interruptions and extends tool life through its cobalt-enhanced steel. Whether you’re working with challenging materials or need consistent, high-precision UNF threads, the Carmex Spiral Point UNF Supercut Tap provides steady performance and predictable outcomes, making it a dependable choice for professional machinists and metalworking shops.
