Meet the OSG UNF Spiral Point Threading Tap—designed for machinists and job shops that need precise, durable through-hole threads in metalworking tasks. Its 3/4-16 UNF size, HSS-E composition, and steam oxide finish work together to deliver reliable performance at higher speeds and with extended tool life.

• Size and thread form: 3/4-16 UNF through-hole threading tap crafted for fine, strong threads in metal
• Material: HSS‑E (high-speed steel with cobalt) for enhanced hardness and heat resistance
• Coating: Steam oxide finish reduces friction and improves wear resistance in tough cutting conditions
• Threading design: Spiral Point geometry promotes efficient chip evacuation, ideal for through-hole tapping
• Application: Optimized for through-hole work, delivering clean, consistent threads with minimal burr
• Brand technology: Backed by OSG’s advanced threading technology for precise results and extended tool life

This tap is the go-to choice for through-hole fastener applications where reliability and accuracy matter. The cobalt-infused steel maintains sharpness under high cutting speeds, while the spiral point channels chips forward, reducing the risk of built-up material inside the hole. Ideal for production environments, it helps maintain thread tolerances and finish quality, reducing rework and downtime.
