The OSG UNC Spiral Point Threading Tap is a precision tool engineered for through-hole threading in metalworking. Ideal for machinists and shops that require consistent, high-quality threads and long tool life, it delivers reliable performance in demanding applications.
- Thread size and type: 1/2" diameter, 13 UNC through-hole threading for fast, reliable taps in common steels and alloys
- Material: HSS‑E (high-speed steel with cobalt) for superior hardness and heat resistance under heavy cutting
- Coating: Steam oxide coating provides enhanced wear resistance and smoother chip flow during tapping
- Design: UNC Spiral Point geometry pushes chips forward, improving evacuation in through-hole work and reducing re-cutting
- Application: Optimized for through-hole tapping in a range of metals, offering dependable performance in production environments
- Durability: Robust construction and advanced metallurgy extend tool life even in high-temperature, high-load machining
This tap helps you achieve precise, repeatable threads with minimal runout, lowering rework and improving part quality. The cobalt-infused HSS-E composition maintains cutting edges longer under heat, while the steam oxide coating reduces friction and wear for sustained performance. Whether you’re building fixtures, components, or assemblies that require clean, accurate threads, this tap delivers consistent results and better overall productivity.
