The OSG UNF Spiral Point Threading Tap No. 1 x 72 is a precision through-hole tapping tool built for machinists and shops that demand consistent, high-quality threads. Crafted for reliable performance in demanding metalworking tasks, it combines advanced materials and geometry to deliver durable, accurate results.

• Thread form: UNF spiral point geometry designed for through-hole tapping with efficient chip evacuation and clean thread formation.
• Material: HSS-E (high-speed steel with cobalt) for enhanced hardness, heat resistance, and longer cutting life.
• Coating: Steam oxide coating provides wear resistance and improved lubricity to extend tool life in tough cutting conditions.
• Through-hole design: Specifically engineered for through-hole applications, ensuring consistent thread quality from entry to exit.
• Size: No. 1 x 72, offering a precise, standardized dimension for reliable compatibility with common through-hole projects.
• Brand reliability: OSG threading taps are engineered for precision and durability, supporting demanding production environments.

This tap is engineered to help you achieve consistent, accurate threads while resisting heat and wear during extended use. The spiral point directs chips forward, minimizing clogging and enabling smoother cutting in through-holes. The combination of HSS-E material and steam oxide coating translates to longer tool life and more predictable performance, even under higher cutting speeds and tougher materials. Ideal for precision assemblies, repetitive production runs, and projects where thread accuracy and reliability are critical. For optimal results, pair with appropriate lubrication and follow recommended tapping speeds to maximize tool life and thread quality.
