The OSG Threading Tap UNF A-Spiral Flute is a right‑hand tapping tool built for precise UNF threads in blind holes, delivering dependable performance in demanding metalworking tasks.

• Thread type: UNF (Unified National Fine) threads designed for blind‑hole tapping.
• Size: 5/8 x 11, DIN2184-1 specification ensures compatibility with metric/imperial standards used in precision manufacturing.
• Material: Powder metal construction provides exceptional durability and wear resistance under high temperatures and extended use.
• Coating: TiCN (Titanium Carbonitride) coating increases hardness and reduces friction for enhanced cutting performance and longer tool life.
• Flute design: A‑Spiral flute optimizes chip evacuation in blind holes, minimizing chip packing and improving reliability during tapping.
• Geometry: Right‑hand threading orientation suited for standard machining setups and common threading operations.
• Application: Ideal for tapping blind holes in metal components where precise UNF threads and clean depth control are critical.

With its combination of powder metal durability and TiCN coating, this tap maintains cutting efficiency at higher speeds and through tougher materials. The spiral flute structure helps keep chips flowing away from the workpiece, reducing the risk of clogging and drill/ tap burial. Users can expect consistent thread quality, improved surface finish, and extended tool life, making it well-suited for production runs and precision assemblies alike.
