The OSG Metric A-Spiral Point Left-Hand Tap is a precision threading tool built for left-handed through-hole applications. Crafted from durable powder metal and finished with a TiCN coating, it delivers reliable performance in demanding machining environments.

• Left-hand threading: Specifically engineered to cut left-handed threads, making it ideal for reverse-rotation assemblies and secure, right-fit joins.
• A-Spiral Point geometry: The spiral point design pushes chips forward, promoting clean threads and reducing the chance of chip clogging inside the hole.
• TiCN coating: Titanium carbonitride coating minimizes friction and wear, extending tool life and improving chip evacuation in tough materials.
• Powder metal construction: High-quality powder-metal body provides toughness and wear resistance for repetitive tapping in challenging metals.
• Through-hole compatibility: Optimized for through-hole DIN 376 tapping, ensuring consistent depth and alignment in the workpiece.
• Size: M22 x 2.5, offering a precise metric thread with a standard coarse pitch suitable for a range of assemblies.

This tap helps you achieve accurate, durable left-hand threads with minimal rework. The TiCN coating lowers friction and heat buildup, while the powder-metal core delivers long-lasting performance under demanding production conditions. The A-Spiral Point geometry ensures efficient chip evacuation, keeping threads crisp and unclogged in through-holes across compatible materials.
