The OSG Threading Tap (Metric Fine, A-Spiral Flute, FORM E) is a right-hand tapping solution crafted for precision in blind-hole applications. Built for engineers and machinists who demand consistent thread quality in fine metric pitches, it delivers reliable performance in challenging hole geometries.
- Size and Pitch: M20 x 2 metric fine thread for precise blind-hole tapping.
- Flute Design: A-Spiral flute technology to promote efficient chip evacuation at higher speeds.
- Material: Powder metal substrate for enhanced wear resistance and durability.
- Coating: TiCN coating increases surface hardness and reduces friction to extend tool life.
- Geometry: FORM E geometry optimized for clean, accurate thread formation in fine pitches.
- Direction: Right-hand threading for standard machining operations.
- Application: Specifically engineered for blind holes, delivering reliable engagement in restricted depths.
- DIN Standard: DIN 374-compliant threading to ensure compatibility with metric fasteners.
This tap is designed to stabilize cutting forces, improve thread quality, and prolong tool life in demanding production environments. The TiCN coating coupled with a powder-metal body reduces wear and heat buildup, supporting longer intervals between tool changes. The combination of FORM E geometry and an A-Spiral flute helps maintain consistent chip flow and minimizes the risk of chip clogging in blind-hole operations. Ideal for precision assemblies in automotive, aerospace, mold making, and general manufacturing where accurate M20 x 2 threads in blind holes are essential.
