The OSG UNF Spiral Flute Threading Tap No. 10 x 32 is a precision threading tool designed for blind-hole tapping, delivering accurate UNF threads with reliable tool life. Built for machinists and shops that demand consistent results in challenging materials.
- Thread format: UNF spiral-flute threading tap, No. 10 x 32 (32 TPI) for fine, precise threads in blind holes.
- Material: HSS-E (high-speed steel with cobalt) for superior hardness and heat resistance under heavy cutting.
- Coating: Steam oxide coating provides a durable surface protection and improved wear resistance.
- Flute design: Spiral flutes promote continuous chip evacuation, reducing clogging and improving cutting in confined blind-hole spaces.
- Intended use: Optimized for blind-hole threading in tough alloys and other challenging materials where space is limited.
With this tap, you’ll achieve clean, to-spec UNF threads quickly and consistently. The cobalt-enhanced HSS-E composition maintains cutting performance at higher temperatures, while the steam-oxide coating extends tool life by resisting wear and corrosion. The spiral-flute geometry minimizes chip buildup in blind holes, lowers the risk of tap breakage, and enables smoother operation in demanding machining tasks. Ideal for precision assemblies and durable fasteners where accurate engagement matters.
