Description
Engineered for high-precision internal threads in blind holes, the OSG Metric A-Spiral Flute Threading Tap delivers durability and efficiency for demanding manufacturing environments. Designed for machinists and engineers who need reliable M2 x 0.4 threads in tight spaces, this tool combines hard-wearing construction with smart chip evacuation.
- Material: Powder metal body provides robust strength and wear resistance for repeated tapping cycles.
- Flute Design: A‑spiral flute enhances chip evacuation in blind holes, helping prevent clogging and improving thread quality.
- Coating: TiCN coating raises surface hardness, reduces friction, and extends tool life under high-speed production.
- Size/Thread: Metric M2 x 0.4 with right-hand threading, aligned to DIN371 standards for compatibility with common tap heads.
- Application: Optimized for tapping blind holes in a range of materials, from softer alloys to tougher steels, in high-demand assemblies.
- Compatibility: Fits standard CNC and manual tapping setups that use DIN371 taps, enabling straightforward integration into existing workflows.
In practice, this tap helps you achieve clean, reproducible threads with fewer interruptions. The combination of powder-metal toughness, a chip‑evacuating flute, and a hard TiCN coating reduces wear and heat, so you can maintain consistent thread quality through longer production runs. With its compact M2 x 0.4 size and right-hand orientation, it’s a reliable choice for precision components, electronics housings, and small mechanical assemblies requiring dependable blind-hole threads.
