The OSG Threading Tap Metric A-LT-Spiral Flute is a high-performance tapping tool designed for precision metric threads in blind holes. Built for machinists and production environments, its LT spiral flute and TiCN coating deliver reliable, long-lasting performance in demanding applications.

• Size: M8 x 1.25 (Metric, right-hand thread)
• Material: Powder metal body for high strength and durability
• Coating: TiCN coating enhances hardness, reduces friction, and extends tool life
• Flute Design: LT (Long Taper) spiral flute for efficient chip evacuation in deep blind holes
• Application: Specifically engineered for threading in blind holes with clean, accurate results
• Orientation: Right-hand cutting direction to suit common metric threading needs

When you pair this tap with the right tap holder and proper lubrication, you’ll achieve consistent thread integrity in challenging blind-hole applications. The LT spiral flute minimizes chip buildup and removes debris quickly, maintaining precise thread geometry even in deep recesses. The TiCN coating reduces wear on high-speed runs, helping sustain productivity and reduce tool changes in demanding manufacturing environments. This tap is ideal for engineers and technicians working on automotive, aerospace, or general mechanical assemblies where reliable, repeatable threads matter.
