OSG's Metric A-spiral flute threading taps are engineered for precision in blind-hole tapping, built for left-hand threads, and finished with a robust TiCN coating for long-lasting performance. Designed to meet DIN 376 requirements, these taps are ideal for challenging blind-hole applications across a range of materials.

• Thread size and hand: M16 x 2, left-hand (LH) threading for controlled reverse-thread assembly and specific machining needs.
• Flute design: A-spiral flute (SFT) optimized for blind-hole tapping to improve cutting action and chip evacuation.
• Material and coating: Powder-metal substrate with TiCN coating for enhanced wear resistance and tool life in demanding environments.
• Standards and compatibility: DIN 376-compliant machine tap configuration, suitable for standardized tooling and consistent results.
• Chip evacuation and reliability: Spiral-flute geometry promotes efficient swarf removal in blind holes, reducing chip clogging and improving thread quality.

These features come together to deliver a durable, high-performance tapping solution for blind-hole projects. The TiCN-coated, powder-metal substrate extends tool life, while the A-spiral flute design and left-hand configuration support smooth, accurate threads in a variety of materials, from general steels to aluminum and stainless steels. Whether you're upgrading existing equipment or tackling a new batch of blind-hole assemblies, this tap is built to help you achieve consistent, reliable results.
