The OSG Threading Tap is a metric A-Spiral Point tool designed for left-handed threading in through-hole applications. Built from powder metal and TiCN-coated for enhanced durability, it delivers reliable, precise threads in M8 x 1.25 DIN371 through-holes.

• Thread size and direction: M8 x 1.25, left-hand through-hole threading with A-Spiral Point geometry
• Material: Powder metal substrate for toughness and wear resistance
• Coating: TiCN coating reduces friction and extends tool life
• Geometry: A-Spiral Point design that efficiently pushes chips forward for clean threads
• Application: Optimized for through-hole, left-hand threading in metal components
• Standard: DIN371-compatible design for consistent performance

Using this tap yields precise, reliable left-hand threads that resist loosening under load. The TiCN coating lowers friction and manages heat, while the powder metal body provides dependable wear resistance across production runs. The spiral-point geometry improves chip evacuation in through-holes, reducing rework and downtime. Ideal for precision left-hand threading in automotive, machinery, and general engineering applications where consistent results matter.
