OSG Threading Tap Metric A-Spiral Point for left-hand threading is a precision tapping tool designed for through-hole applications. Made from durable powder metal and finished with a TiCN coating, it’s built to deliver reliable performance in demanding manufacturing environments.

• Left-Hand Threading (LH): Specifically engineered for left-hand threads, ideal for through-hole assemblies and applications requiring reverse-thread operation.
• A-Spiral Point Design: The spiral point pushes chips forward, delivering clean, continuous threads and reducing the risk of chip clogging during tapping.
• Powder Metal Substrate: Robust core material that offers excellent wear resistance and heat tolerance for repeated use in production settings.
• TiCN Coating: Hard, friction-reducing coating that extends tool life and improves chip evacuation, especially in tougher materials.
• Through-Hole Capability: Optimized geometry for through-hole tapping, providing stable alignment and consistent thread quality from start to finish.
• Size & Standard: M20 x 2.5 metric thread with DIN 376 compatibility, ensuring reliable fit and performance in standard-sized assemblies.

When you need dependable left-handed threads in through-holes, this OSG tap balances durability, precision, and efficiency. The TiCN coating lowers operating temperatures and wear, while the A-Spiral Point design keeps chips moving forward for smoother cuts and reduced rework. The combination of powder metal toughness and DIN 376 conformity makes it a practical choice for automotive, machinery, and general metalworking tasks that demand consistent, repeatable results.
