Learn more about Klarna
Description
The OSG Threading Tap Metric A-Spiral Flute is a right-hand tapping tool designed for precision blind-hole threads. Built from durable powder metal and TiCN coated, it delivers consistent results and extended tool life in demanding production environments.
- Material: Powder metal construction delivers superior strength and wear resistance for repeated tapping in challenging materials.
- Coating: TiCN coating increases hardness and reduces friction, helping the tap last longer under high-speed production.
- Flute Design: A-Spiral flute enhances chip evacuation, reducing buildup in deep or blind holes for cleaner threads.
- Thread Type: Right-hand metric thread for standard applications and reliable performance.
- Size: M6 x 1 thread pitch, suitable for common metric blind-hole projects.
- Application: Specifically optimized for blind holes, providing accurate threads with minimal resistance.
- Standard: DIN 376 compliance ensures compatibility with established tooling and processes.
This tap combines a robust powder-metal body with a hard-wearing TiCN coating to withstand wear and heat in high-speed tapping. The A-Spiral flute design supports efficient chip evacuation, which translates to fewer insertions, fewer reworks, and more consistent thread quality in deep blind holes. Ideal for professional machinists and precision manufacturers, it helps maintain production pace while delivering reliable, repeatable results that meet DIN 376 specifications.
