The OSG Metric A-Spiral Point Threading Tap is a precision through-hole tap designed for fast, clean thread production in a range of materials. Built for high-speed tapping, its A-spiral point aggressively pushes chips ahead to minimize clogging and maximize cutting efficiency.

• Size and pitch: M3 x 0.5 metric threading, optimized for through-hole tapping to standard DIN376 dimensions.
• A‑Spiral Point design: directs chips forward, reducing chip packing and improving thread finish in through-holes.
• Material: Powder metal for enhanced wear resistance and longer tool life in demanding machining conditions.
• Coating: TiCN coating lowers friction and improves heat resistance, extending cutting life under high-speed operation.
• Cutting direction: Right-hand threading, suitable for common assembly and fastening applications.
• Through-hole compatibility: specifically engineered for tapping through-holes with consistent thread accuracy.
• DIN 376 alignment: constructed to meet the DIN 376 specification for reliable interchangeability and performance.

This tap delivers precise, repeatable threads with minimal burrs, making it ideal for rapid production runs or high-precision assemblies. The combination of powder-metal substrate and TiCN coating provides durable performance across a variety of materials, helping to reduce tool changes and downtime while ensuring dependable thread quality in through-holes.
