The OSG Metric A-Spiral Point LH Tap is a left-hand threading tool designed for through-hole assemblies. Built with a powder metal substrate and a TiCN coating, it delivers durable, reliable performance for precise left-handed threads at a through-hole DIN 376 size—M12 x 1.75.

• Thread Direction: Left-hand (LH) threading designed for specific reverse-thread applications in through-holes
• Material: Powder metal construction for enhanced toughness, wear resistance, and long tool life
• Coating: TiCN (Titanium Carbonitride) coating reduces friction and improves heat resistance to extend life
• Geometry: A-Spiral Point geometry efficiently pushes chips forward for clean, accurate threads
• Through-Hole Compatibility: Optimized for through-hole DIN 376 standards and precise tapping in cylindrical components
• Size: M12 x 1.75 pitch for standard left-hand thread applications

Designed to deliver dependable left-handed tapping in demanding materials, this tap minimizes chip packing and provides consistent thread quality. The combination of a robust powder metal core and TiCN coating helps withstand high-speed tapping, maintain sharp cutting edges, and reduce maintenance downtime. It's an ideal choice for technicians and engineers working on assemblies that require reliable LH threads in through-hole configurations, offering a clear advantage over generic taps when precision and tool life matter.
