The OSG UNF Threading Tap with A-Spiral flute is a precision tapping tool designed for engineers and machinists who work with blind holes. Built for durability and high-speed performance, it delivers clean, accurate UNF threads in recessed features.
- UNF A-Spiral Flute Design: Efficient chip evacuation in blind holes, reducing clogging and improving hole quality during tapping.
- Powder Metal Construction: Robust, wear-resistant body that stands up to repeated tapping and elevated temperatures for longer tool life.
- TiCN Coating: High hardness with reduced friction, enabling smoother cuts and extended service life in demanding machining conditions.
- Right-Hand Thread: Optimized for standard right-handed UNF threads to match common fasteners and assemblies.
- Size and DIN Compatibility: 3/4" diameter with 10 TPI UNF thread, designed for blind-hole tapping per DIN 2184-1.
This tapping solution helps you achieve precise, burr-free UNF threads in blind holes with consistent diameter control. The spiral flute aids debris removal, reducing heat buildup and downtime between tool changes. The TiCN coating supports higher-speed machining and longer tool life, making it well suited for automotive, aerospace, and general precision manufacturing where reliable blind-hole tapping is essential.
