The OSG Metric A-Spiral Point Left-Hand Threading Tap is a precision tool designed for through-hole applications that require left-handed threads. Built from durable powder metal and finished with a TiCN coating, it delivers reliable performance across demanding materials while maintaining smooth, consistent cutting action for M6 x 1 threads.

• Thread Type: Metric left-hand threading with A-Spiral Point geometry to push chips forward and promote clean thread formation in through-holes
• Material: Powder metal construction for improved wear resistance and heat tolerance under tapping workloads
• Coating: TiCN coating reduces friction, extends tool life, and enhances chip evacuation during tapping
• Size & Standard: M6 x 1 through-hole tap, DIN371 compliant, suitable for standard left-hand thread production
• Application: Optimized for through-hole tapping in a variety of base materials, delivering consistent thread quality
• Brand Assurance: OSG engineering and manufacturing expertise behind a reliable, shop-tested tapping solution

This left-hand through-hole tap is particularly valuable for assemblies that rely on reverse-thread applications or components that require secure, oppositely threaded fasteners. The combination of powder-metal durability and TiCN-coated wear resistance supports longer tool life and fewer interruptions in production. The A-Spiral Point design helps maintain steady chip flow, minimizing clogging and reducing the need for rework, while the DIN371 specification ensures compatibility with common left-hand threading standards. Whether you’re performing initial production runs or field maintenance, this tap delivers precise, repeatable results with a focus on reliability and efficiency.
