The OSG Threading Tap Metric A-Spiral Point - LH Powder Metal Left Hand - TiCN Coated is a precision left-hand threading tap designed for through-hole work in metric sizes. Built for machine shops, maintenance teams, and production environments that require reliable left-hand threads, this tap delivers durable performance and extended tool life.

  • Left-Hand Threading: Specifically designed for left-handed threads in through-hole applications, enabling accurate tapping with the correct thread direction in CNC and manual setups.
  • Metric Size: M18 x 2.5 through-holes, engineered to DIN 376 standards for reliable fit and performance in metric applications.
  • Material: Powder metal construction provides high wear resistance and toughness for demanding tapping tasks.
  • TiCN Coating: Hard coating reduces friction, improves heat resistance, and extends tool life under heavy cutting conditions.
  • A-Spiral Point Design: Spiral-point geometry efficiently pushes chips forward, yielding cleaner threads and minimizing chip buildup in through-holes.
  • DIN 376 Through-Hole Standard: Engineered to meet DIN 376 specifications for through-hole tapping consistency and compatibility.

When you need reliable left-hand threads in through-holes, this OSG tap offers a durable, high-performance solution. The combination of TiCN coating and powder-metal substrate delivers long service life and steady performance across materials. The spiral point design enhances chip evacuation for cleaner threads, reducing rework and downtime. The M18 x 2.5 size is well-suited for larger fasteners and robust assemblies, making it a preferred choice in automotive, industrial equipment, and precision manufacturing environments where left-hand fasteners are essential.
