The OSG Threading Tap UNF A-Spiral Flute is designed for precise tapping of UNF threads in blind holes, offering durability and reliable performance for professional machinists. Built with a powder-metal body and TiCN coating, it stands up to demanding high-speed applications while delivering consistent thread quality.

• Thread Type: UNF (Unified National Fine) threads for precise, high-tolerance tapping in blind holes.
• Flute Design: A-Spiral flute promotes efficient chip evacuation, reducing clogging in blind-hole work.
• Material: Powder-metal construction provides enhanced toughness and wear resistance at elevated cutting speeds.
• Coating: TiCN coating increases hardness, lowers friction, and extends tool life in demanding environments.
• Orientation: Right-hand geometry optimized for standard machining workflows and common fastener directions.
• Size and Standard: M12 x 24, DIN 2184-1, compatible with common industrial fastener specifications.
• Application: Ideal for blind-hole tapping in metal components where precise UNF threads are required.

With a durable powder-metal core and a low-friction TiCN coating, this tap maintains cutting efficiency across longer production runs and challenging materials. The A-Spiral flute ensures smooth chip evacuation, minimizing the risk of chip packing and tool breakage in blind holes. This combination supports clean, accurate thread formation, reduces downtime for tool changes, and helps maintain consistent thread quality in aerospace, automotive, and general precision machining projects.
