The OSG UNF A-Spiral Flute Threading Tap is engineered for precise tapping of UNF threads in blind holes, delivering dependable performance for small, value-critical assemblies.

• Thread type: UNF (Unified National Fine) with A-Spiral flute optimized for blind-hole tapping
• Material: Powder metal construction for enhanced durability and wear resistance under demanding conditions
• Coating: TiCN coating increases hardness and reduces friction to extend tool life
• Flute design: A-Spiral flute facilitates efficient chip evacuation in blind holes and helps prevent clogging
• Hole type: Specifically suited for blind holes where access is limited
• Direction: Right-hand threading for common fastening applications
• DIN standard: DIN 2184-1 specification ensures compatibility with standard UNF tapping tools
• Size: M2 x 56, compact and precise for small screw-thread applications

This tap delivers reliable performance in production or manual tapping, with TiCN coating helping maintain consistent cutting action during high-speed cycles. The combination of powder-metal durability and spiral flute geometry minimizes wear and chip buildup, supporting steady thread quality and longer tool life in blind-hole work.
