The OSG Metric Fine A-Spiral Flute Threading Tap is designed for precision threading in blind-hole applications, ideal for machinists who demand clean, accurate threads in challenging materials. Built with FORM E geometry, a TiCN-coated powder-metal body, and an A-Spiral flute, it delivers durable performance and efficient chip evacuation in one tool.

• FORM E geometry: Optimized cutting design for high-precision, fine-pitch metric threads in blind holes.
• Powder-metal construction: Robust wear resistance and toughness to extend tool life in demanding materials.
• TiCN coating: Hardened surface reduces wear and lowers friction for smoother cutting and longer service intervals.
• A-Spiral flute design: Superior chip evacuation at higher speeds, minimizing chip buildup in through or blind-hole tapping.
• Right-hand threading: Standard orientation compatible with common machining setups and fixtures.
• Blind-hole suitability (DIN374): Specifically engineered to form reliable threads in non-through holes with consistent depth.
• Size and pitch: M20 x 1 metric fine thread, DIN 374 compliant for common industrial applications.

This tap delivers crisp thread form, improved tool life, and dependable performance in production environments where blind-hole threads must be precise and repeatable. The combination of FORM E geometry, powder-metal durability, and TiCN hardness helps reduce rework and downtime, making it well-suited for mold making, automotive components, and precision machinery that rely on accurate, durable blind-hole threads.
