Learn more about Klarna
Description
Engineered for precision threading in blind holes, the OSG Metric A-Spiral Flute Tap delivers reliable performance for metalworking professionals and production shops. Sized for M6 x 1 right-hand threads, it combines a TiCN-coated, powder-metal body with an A-spiral flute to sustain fast, clean cuts in demanding materials.
- Size / Thread: M6 x 1 metric, right-hand thread, optimized for standard metric applications.
- Material: Powder-metal construction delivers toughness and wear resistance for repetitive tapping.
- Coating: TiCN coating increases surface hardness and reduces friction, extending tool life in tough materials and high-speed operations.
- Flute design: A-Spiral flute enhances chip evacuation in blind holes, reducing clogging and improving stability during deep thread cutting.
- Hole type: Specifically designed for blind holes, enabling reliable tapping without the need for through-holes.
- DIN standard: Conforms to DIN371 specification for reliable geometry and compatibility with DIN taps.
- Manufacturer: OSG, a trusted name in precision threading tooling.
- Application: Ideal for metalworking tasks in steel, aluminum, and other alloys where clean, accurate M6 x 1 threads are required.
With this tap, you can achieve consistent thread quality in blind holes, reduce tool wear, and shorten cycle times on high-volume production lines. The TiCN coating minimizes friction for smoother cutting, while the A-Spiral flute keeps chips moving away from the cutting edge, helping prevent breakage and rework. The result is reliable performance, fewer tool changes, and a longer service life per tool.
