The OSG Threading Tap is a precision tool designed for efficient threading of blind holes in a range of materials. Built with powder-metal construction, TiCN coating, and an A-Spiral flute, it delivers dependable performance for production environments that demand exacting threads in tight cavities.
- Material: Powder-metal construction delivers high strength and wear resistance for repeated use.
- Coating: TiCN coating increases surface hardness and reduces friction, extending tool life in high-speed tapping.
- Flute Design: A-Spiral flute provides efficient chip evacuation in blind holes, minimizing chip buildup and binding.
- Thread Type: Metric A-Spiral flute with right-hand threading for standard tapping operations.
- Size: M2.5 x 0.45 thread geometry (DIN371) for consistent pitch and fit.
- Application: Ideal for tapping blind holes in metals and alloys with reliable, repeatable results.
With the OSG thread tap, you can achieve clean, accurate threads in blind holes without frequent tool changes. The TiCN coating reduces wear and heat generation, while the flute design improves chip evacuation to prevent binding in deep cavities. This makes it a reliable choice for high-production environments and precision assemblies that demand durable, long-lasting tapping performance.
