Description
The OSG Threading Tap Metric A-OIL-Spiral Flute is a high-performance tapping solution designed for reliable threading in blind holes. Built for precision-focused environments, it combines rugged powder-metal construction with advanced TiCN coating to deliver long-lasting, consistent results in M8 x 1.25 applications.
- Material: Powder-metal body for enhanced strength and fracture resistance in demanding hole depths.
- Coating: TiCN coating increases hardness and wear resistance while reducing friction for smoother cuts and extended tool life.
- Flute Design: A-OIL spiral flute optimizes chip evacuation, minimizing clogging in deep or blind-hole threading operations.
- Thread Type: Right-hand tap designed for standard external-threading compatibility and predictable performance.
- Size: M8 x 1.25 with DIN371 geometry to ensure accurate thread formation in blind holes.
- Application: Specifically engineered for blind-hole threading in high-demand production environments requiring reliability and repeatability.
This tap is ideal for assemblies and fixtures where blind-hole threads must be created cleanly and consistently. The combination of powder-metal strength and TiCN wear resistance helps minimize tool changes and rework, while the spiral flute design promotes efficient chip removal for deeper holes. For shops aiming to improve throughput without compromising thread quality, this OSG tap provides a practical, durable solution that meets DIN371 specifications.
