Experience precise through-hole threading with the OSG UNF Spiral Point Threading Tap. Designed for professional machining tasks, it combines a cobalt-enriched high-speed steel core with a durable Steam Oxide coating to deliver reliable, high-quality UNF threads and extended tool life.

• Threading type: UNF Spiral Point design for efficient chip evacuation and smooth thread formation in through-hole applications.
• Material: HSS‑E (high-speed steel with cobalt) for increased hardness and heat resistance during demanding cuts.
• Coating: Steam Oxide coating to reduce wear, improve wear resistance, and enhance tool longevity.
• Through-hole suitability: Specifically engineered for through-hole threading, providing consistent results in via holes and long through-holes.
• Size and length: Nominal size No. 2 with an overall length of 64 mm for versatile use across common through-hole tasks.
• Performance: Optimized geometry and construction deliver stable cutting action, reliable thread quality, and extended tool life even at higher speeds.

This tap is ideal for shops and job sites that require durable, high-precision UNF threads in through-hole work. The combination of HSS‑E cobalt, steam oxide coating, and spiral point geometry helps you complete projects with fewer passes, cleaner finishes, and longer-lasting tooling — turning challenging threading tasks into routine, dependable results.
