Carmex Threading Tap - Spiral Point - UNF Supercut Tap - HSS-E - No. 12 x 28

Designed for professionals and advanced hobbyists, the Carmex Spiral Point UNF Supercut Tap delivers precise UNF threading with dependable durability. Crafted from cobalt-rich HSS-E, it thrives in tough materials and high-speed threading environments, enabling clean, accurate threads with fewer reworks.

• Tap Type: Spiral Point design for efficient chip evacuation and clean starting threads, helping maintain tolerance and reduce thread deformation.
• Thread Standard: UNF (Unified National Fine) compatibility for fine-pitch threads and precise engagement in smaller diameters.
• Material: HSS-E (high-speed steel with cobalt) for improved heat resistance, wear resistance, and longer tool life under demanding speeds.
• Size: No. 12 x 28, a versatile size for common UNF tapping tasks in mid-range diameters.
• Chip Control: Spiral groove geometry channels chips toward the exit to minimize clogging and improve thread quality in blind and through holes.
• Durability: Cobalt-infused alloy supports sustained cutting performance at elevated temperatures, reducing the risk of work-hardening during heavy-duty tapping.

With this tap, you gain reliable engagement, reduced rework, and longer tool life, thanks to superior heat resistance and efficient chip evacuation. It’s well-suited for machining stainless steel, alloyed steels, and other unforgiving materials where UNF threads are required, ensuring fast, consistent results in every project.
