Description
The OSG Threading Tap Metric Fine A-Spiral Point is a precision tapping solution designed for through-hole applications. Built for machinists, engineers, and serious hobbyists, it delivers accurate fine-pitch M5 x 0.5 threads with enduring tool life.
- Thread size and pitch: Metric fine thread M5 x 0.5, tuned for precise, small-diameter tapping in through-holes (DIN371 standard).
- Coating: TiCN coating reduces friction, improves wear resistance, and extends tool life in demanding materials and speeds.
- Material construction: Powder metal core combines toughness with heat resistance for reliable performance under high-speed tapping.
- A-Spiral Point design: Spiral-point geometry efficiently pushes chips forward, enhancing thread quality and reducing scraping or back-cutting.
- Arrangement and direction: Right-hand thread optimized for common machining setups and standard fastener assemblies.
- Application: Specifically engineered for through-hole tapping and DIN371 compatibility across a range of metals and thicknesses.
When you need clean, accurate threads in through-holes, this OSG tap delivers consistent results with reduced chip clogging and smoother cutting action. The combination of a powder metal core and TiCN coating translates to longer tool life, dependable performance at higher speeds, and better surface finishes on the workpiece. Whether you're building tight-tolerance assemblies or completing frequent production runs, it provides reliable threading that aligns with DIN371 specifications and supports efficient, repeatable outcomes.
