Description
The OSG Threading Tap is a metric A-Spiral Flute tap designed for blind-hole threading, built for machinists who demand precision in tight spaces. With a TiCN-coated powder-metal body and a 6GX tolerance, it delivers consistent, durable performance on small-diameter threads (M2 x 0.4).
- Thread size and tolerance: M2 x 0.4 with 6GX tolerance for precise, repeatable thread fits.
- A-Spiral Flute design: Optimizes chip evacuation in blind holes to reduce clogging and improve tapping efficiency.
- Material: Powder Metal construction delivers strength and wear resistance for extended tool life.
- Coating: TiCN coating increases surface hardness and lowers friction during cutting.
- Drive direction: Right-Hand taps for standard clockwise threading on common materials.
- Application: Specifically suited for blind-hole threading in DIN371-compliant processes and assemblies.
- Standard: DIN371 compatibility ensures alignment with established machining practices.
In practice, this tap provides clean, accurate threads with reliable performance in confined spaces. The combination of spiral flute, robust powder-metal core, and TiCN coating helps resist wear, extend tool life, and maintain consistent results across repetitive runs. Ideal for high-precision small-diameter applications where thread integrity matters.
