The OSG Threading Tap Metric A-Spiral Point - LH Powder Metal Left Hand - TiCN Coated - Through Holes DIN371 - M5 x 0.8 is a precision threading tap designed for left-hand threads in through-hole applications. Built from durable powder metal and TiCN-coated to reduce wear, it delivers reliable, clean threads in demanding materials.

• Thread Type: Left-Hand (LH) spiral point design for efficient chip evacuation in through-hole tapping.
• Material: Powder metal construction for durability, wear resistance, and robust performance under load.
• Coating: TiCN coating reduces friction, extends tool life, and improves chip control during cutting.
• Size & Pitch: M5 x 0.8 metric thread for standard through-hole assemblies.
• Through-Hole Application: Optimized for tapping threads that extend completely through the workpiece.
• DIN Standard: Compatible with DIN371 through-hole tapping specifications for consistent results.

The combination of a spiraled point, left-hand threading, and TiCN coating translates to smoother cutting action, fewer re-taps, and longer tool life in challenging materials. The spiral point actively pushes chips forward, reducing clogging and ensuring clean, accurate threads on each pass. Whether you’re assembling components that require reverse-threaded fasteners or performing maintenance on gear and machinery, this tap offers dependable performance, repeatable results, and a clear path to efficient left-hand tapping in DIN371 through-holes.
