The Carmex Threading Tap, Spiral Flute UNC Supercut Tap, built from HSS-E, is designed for professionals who need precise Unified National Coarse threads with durable, high-speed performance.

• Tap Size: No. 12 x 24 UNC — standard coarse-thread specification for reliable UNC tapping
• Flute Design: Spiral flute for efficient chip evacuation and reduced risk of clogging
• Material: HSS-E (high-speed steel with cobalt) for enhanced hardness, heat resistance, and tool life
• Cutting Geometry: Carmex Supercut geometry to deliver smooth initiation and consistent thread formation
• Applications: Optimized for UNC threading in demanding materials and high-speed machining environments

This tapping solution helps you achieve clean, accurate threads with minimal effort. The spiral flute clears chips quickly, reducing heat buildup and chatter, while the HSS-E construction stands up to tougher materials and longer runs. The Supercut geometry supports a confident cut from start to finish, making it a dependable choice for production, maintenance, and precision prototyping where UNC threads are required.
