Achieve precise internal threads in blind holes with the OSG UNC Spiral Flute Threading Tap No. 2 x 56. Designed for professional machinists and rigorous shop environments, it delivers durable performance and consistently accurate threads in demanding materials.

• No. 2 UNC Thread: No. 2 size with 56 threads per inch (UNC) for standard internal threads.
• Flute Design: Spiral flute geometry enhances chip evacuation, reducing clogging in blind-hole taps.
• Material: HSS-E (high-speed steel with cobalt) for increased hardness and wear resistance.
• Coating: Steam Oxide coating to boost durability and heat resistance during tapping.
• Application: Optimized for blind-hole threading to produce clean, accurate threads in confined depths.
• Precision & Longevity: Engineered to deliver high-precision threads with extended tool life in demanding machining tasks.

This threading tap combines advanced materials and geometry to help you achieve reliable, repeatable results. The HSS-E composition stands up to higher temperatures, while the steam oxide finish reduces wear over time. The spiral flute aids debris removal, making it well-suited for blind-hole work where chip control matters. Use it for precise internal threads in metalworking projects, from maintenance and repair to production runs, and expect consistent thread quality with fewer re-cuts.
