Description
The OSG Threading Tap is a metric A-Spiral Point tapping tool designed for through-hole applications. Built for machinists and precision fabricators, it delivers fast, clean threads with extended tool life.
- Size and pitch: M2.5 x 0.45
- A-Spiral Point design: aggressively pushes chips ahead of the tool to reduce clogging and improve cutting efficiency
- Material: Powder Metal body offers enhanced wear resistance for longer tool life
- Coating: TiCN coating lowers friction and improves heat resistance, extending performance during high-speed tapping
- Threading direction: Right-Hand threading suitable for standard through-hole fasteners and components
- Through-hole compatibility: Engineered specifically for through-hole DIN371 requirements, ensuring reliable alignment and consistent results
This tap is ideal for high-performance threading across a wide range of materials, providing precise, repeatable threads with smooth entry and steady cutting action. Its combination of powder-metal durability and TiCN coating helps reduce tooling costs over time by resisting wear and maintaining sharpness through demanding production runs.
