The OSG UNF Spiral Point Threading Tap is built for precision through-hole threading in demanding production environments. Crafted from HSS-E cobalt and finished with a steam oxide coating, this tap combines outstanding hardness, heat resistance, and durability to deliver consistent, high-quality threads.

• Thread Form: UNF spiral point design optimized for through-hole tapping, promoting efficient forward chip evacuation.
• Material: High-speed steel with cobalt (HSS-E) for enhanced hardness and heat tolerance during prolonged use.
• Coating: Steam oxide coating adds durability and corrosion resistance, helping the tool withstand demanding machining conditions.
• Size: 7/8" major diameter with 14 threads per inch (7/8 x 14 UNF) for precise, fine-pitch threading.
• Flute Design: Spiral point features tailored geometry to push chips out of the hole, reducing clogging and improving surface finish.
• Application: Ideal for through-hole applications where clean, accurate UNF threads are critical and fast, reliable threading is required.

This threading tap is designed to maintain sharpness and achieve repeatable results across production runs. The combination of HSS-E cobalt and steam oxide coating supports longer tool life, steady performance under heat, and precise thread profiles, making it a dependable choice for critical machining tasks.
