The OSG Threading Tap UNC A-Spiral Flute is a high-performance tapping tool designed to create UNC A threads in blind holes with precision and repeatable results. Built for professional workshops and production environments, it blends durability with efficient chip removal for smooth, reliable tapping outcomes.

• Threading standard: UNC A — optimized for Unified National Coarse threads in blind holes, delivering robust thread forms and dependable engagement.
• Flute design: Spiral flute for efficient chip evacuation in blind-hole tapping, helping to prevent clogging and improve finish.
• Material: Powder metal body provides durable wear resistance and strong mechanical performance in demanding applications.
• Coating: TiCN coating increases hardness and lowers friction, extending tool life and enabling steadier cuts at higher speeds.
• Direction: Right-hand tapping aligns with standard machining setups for conventional thread production.
• Application: Specifically designed for blind holes to produce clean, accurate threads with minimized breakout risk.
• DIN standard: Meets DIN2184-1 specification for consistency and interchangeability in industrial environments.
• Size: M12 x 24 — metric sizing tailored to common fastener specifications and depth requirements.
• Performance: Optimized for high-speed and high-precision tapping operations, enabling efficient production cycles.

This tapping solution delivers longer tool life, cleaner UNC threads, and reliable performance across repeated production runs. The TiCN coating reduces wear and friction, while the powder-metal substrate provides the toughness needed for demanding blind-hole applications. The spiral flute enhances chip removal, lowering the risk of buildup that can compromise thread quality. Ideal for production environments such as automotive components, machinery housings, and precision assemblies, this tap helps maintain consistent thread accuracy and efficient turnaround. For best results, use proper lubrication and appropriate speeds/feeds to maximize tool life and threading quality.
