The OSG Threading Tap Metric A-LT-Spiral Point is a high-performance through-hole threading tool designed for precise, reliable M3 x 0.5 threads. Built for machinists and production shops, it combines durable materials and a smart coating to deliver consistent results across small-diameter projects.
- Material: Powder-metal construction delivers exceptional strength, wear resistance, and heat tolerance for demanding threading tasks.
- Coating: TiCN coating minimizes friction, enhances chip flow, and supports higher cutting speeds with reduced tool wear.
- Thread geometry: Spiral Point (LT) design efficiently pushes chips forward, reducing clogging and producing cleaner internal threads in through-holes.
- Hand: Right-hand threading standard, suitable for the majority of materials and applications.
- Application: Optimized for through-hole DIN371 threads, ensuring dependable performance in insert-ready internals and assemblies.
- Size: Metric M3 x 0.5, aligned with DIN371 threading standards for compatibility with common components.
This tap is ideal for electronics enclosures, small-mechanical assemblies, and precision fixtures where through-hole threads must be accurate and durable. The combination of powder-metal substrate and TiCN coating extends tool life, while the spiral point geometry promotes efficient chip evacuation for smoother, more consistent threading. A practical choice for shops aiming to reduce cycle times without compromising thread quality.
