The OSG UNF Spiral Point Threading Tap is a precision threading tool designed for through-hole work in professional machining environments. Built for durability and consistent performance, it delivers accurate UNF threads with smooth chip evacuation.

• UNF Spiral Point Design: The spiral point geometry pushes chips forward, enabling efficient chip evacuation and smooth cutting in through-holes.
• Material: High-Speed Steel with Cobalt (HSS-E) for excellent wear resistance and heat tolerance during demanding tapping.
• Coating: Steam Oxide coating reduces friction, enhances surface finish, and provides additional corrosion protection for longer tool life.
• Size and Thread: 3/8" diameter with 24 threads per inch (UNF) for fine-pitched, precise threading.
• Through-Hole Application: Specifically optimized for through-hole tapping, delivering clean threads with minimal chip interference.
• Brand Advantage: OSG’s advanced threading technology supports consistent performance and extended tool life in production environments.

When you use this tap, you gain precise thread formation, longer tool life, and reduced downtime due to fewer tool changes. The combination of HSS-E and steam oxide coating handles high-temperature cutting, while the spiral point ensures reliable chip evacuation—crucial for through-hole work and high-speed tapping. This tap is ideal for critical machining tasks where accurate UNF threads and repeatable results matter, helping you maintain tight tolerances and finish quality across multiple holes.
