The OSG Threading Tap Metric A-Spiral Point LH is a precision left-hand tapping tool designed for through-hole applications. Built from durable powder-metal and finished with a multilayer TiCN coating, this tap delivers reliable, clean threads in metric sizes like M3 x 0.5.

• Material: Powder-metal construction provides a tough, wear-resistant core designed for repeated tapping cycles.
• Coating: Multilayer TiCN coating reduces friction and extends tool life in demanding through-hole applications.
• Geometry: A-Spiral Point (A-POT) design that pushes chips forward, helping maintain clean threads in through holes.
• Thread Direction: Left-hand threading (LH) for reverse-threaded assemblies and specialized fastening tasks.
• Hole Type: Optimized for through-hole tapping with DIN371 compatibility for metric thread standards.
• Size: M3 x 0.5 cutting size for precise metric threads.

This tap is built to deliver dependable performance in production or workshop settings. The powder-metal substrate combined with TiCN coating minimizes wear and heat buildup, while the spiral-point geometry reduces chip congestion and improves cycle times in through-hole work. The LH orientation makes it ideal for applications requiring reverse-threaded fasteners or specialized assemblies, all while adhering to DIN371 standards for consistent, interchangeable results.
