Achieve precise threading with the OSG UNF Spiral Flute Threading Tap. Designed for professional machining tasks, this HSS-E cobalt tap delivers accurate UNF threads in blind-hole applications with outstanding durability.

• UNF Spiral Flute Design: Spiral flutes provide efficient chip evacuation in blind holes, helping maintain steady cutting action and consistent thread quality.
• Size and Thread: 5/16" diameter with 24 threads per inch (5/16 x 24 UNF).
• Material: High-Speed Steel with cobalt (HSS-E) for greater hardness and resistance to heat and wear during cutting.
• Coating: Steam oxide coating enhances wear resistance and tool life in demanding machining environments.
• Application: Optimized specifically for blind-hole threading, minimizing chip buildup and reducing rework.
• Quality and Reliability: Built by OSG, leveraging advanced threading technology to deliver accurate threads and dependable performance.

This tap enables clean, true UNF threads in tight blind-hole work. The cobalt-infused substrate withstands heat and friction, while the spiral flute design promotes smooth chip removal to maintain cutting efficiency. For precise, durable threading in metalworking tasks, the OSG UNF Spiral Flute Threading Tap is a trusted choice that supports consistent results and longer tool life.
