The Carmex Threading Tap with Spiral Flute in UNF Supercut geometry is a precision tapping tool designed for professionals who work with 5/16-24 UNF threads. Built from cobalt-containing high-speed steel, it delivers reliable performance in challenging materials and high-speed threading operations.

• Thread type and size: Spiral-flute UNF Supercut tap for 5/16-24 threads, optimized for accurate threading in tight holes.
• Material: HSS‑E (high-speed steel with cobalt) for enhanced heat resistance and longer tool life in tough cutting conditions.
• Flute design: Spiral flutes provide efficient chip removal, reducing clogging and enabling smooth cutting action.
• Cutting geometry: Supercut geometry supports stable cutting and true thread formation even in demanding materials.
• Drive/shank: Square drive end for secure engagement with tapping wrenches and compatible tools.

Benefits: Expect clean, consistent UNF threads with improved reliability when working in harder metals or high-speed environments. The cobalt-infused HSS-E construction resists heat buildup, extending tap life and reducing downtime. Efficient chip evacuation from the spiral flutes minimizes chatter and thread distortion, making this tap well suited for automotive fittings, precision instrumentation, and other applications where precise 5/16-24 UNF threads matter.
