The OSG Threading Tap is a precision metric tool designed for tapping blind holes with reliability and precision. Tuned for M1.1 x 0.25 threads, it combines a powder-metal body, TiCN coating, and an A‑spiral flute to deliver consistent, high-quality threads in demanding production environments.
- Size and thread: M1.1 × 0.25 metric thread for small-diameter, high-precision applications
- Flute geometry: A‑spiral flute design enhances chip evacuation in blind holes, reducing clogging and improving finish
- Material: Powder-metal body for improved toughness and wear resistance under heat and high-speed tapping
- Coating: TiCN coating increases hardness and lowers friction for longer tool life
- Direction and standard: Right‑hand thread aligned with DIN371 for reliable, consistent threading
- Hole type: Optimized for blind holes, enabling deeper threads with better control
- Application: Suitable for high-speed production environments and a range of materials requiring precise blind-hole threads
The TiCN coating and powder-metal construction work together to extend tool life and maintain dimensional accuracy across production runs. The A‑spiral flute efficiently evacuates chips from deep blind holes, minimizing tool deflection and rework while delivering smooth, consistent threads. This tap is ideal for small-diameter, high-precision assemblies where reliable thread engagement is critical. To maximize performance, use appropriate cutting fluid, follow recommended tapping speeds, and ensure proper alignment for clean, repeatable results.
