Achieve precise threading for through-hole applications with the OSG UNF Spiral Point Threading Tap. Built from cobalt-enhanced HSS (HSS-E) and finished with a robust steam oxide coating, this tap is designed for durable, high-accuracy UNF 7/16-20 threads in demanding machining tasks.

• Threading Type: UNF Spiral Point design that aids chip evacuation and enables efficient through-hole tapping.
• Material: HSS-E (high-speed steel with cobalt) for improved hot hardness and wear resistance.
• Coating: Steam Oxide coating to reduce friction, enhance lubricity, and extend tool life.
• Size / Pitch: 7/16" x 20 UNF, optimized for through-hole applications.
• Through-Hole Compatibility: Specifically designed for through-hole tapping where chips need to be expelled ahead of the edge.
• Applications: Ideal for steel and alloy workpieces in production runs, repair work, and precision assemblies.

With the OSG UNF Spiral Point Threading Tap, you’ll achieve clean, accurate thread forms and longer tool life in demanding environments. The cobalt-infused HSS-E material withstands higher temperatures, while the steam oxide finish lowers friction and improves lubrication retention. The spiral point geometry directs chips out of the hole, reducing the risk of clogging and ensuring consistent performance across multiple taps. This combination makes it a reliable choice for critical machining tasks that require dependable UNF threads and repeatable results.
