Description
OSG’s Metric A-OIL-Spiral Flute Threading Tap is a high-performance tool designed to create precise threads in blind holes. Built for demanding production environments, it combines rugged powder-metal construction with a hard TiCN coating to deliver reliable performance and extended tool life.
- Thread size and standard: M30 x 3.5, DIN 376 compatible for consistent, industry-standard threads.
- Material: Powder metal construction for superior strength and fatigue resistance in tough drilling and tapping tasks.
- Coating: TiCN coating enhances hardness and wear resistance, minimizes friction, and extends insert life.
- Flute design: A-OIL spiral flute optimizes chip evacuation, improving cutting efficiency in deep or blind holes.
- Rotation and direction: Right-hand threading for straightforward operation in typical production setups.
- Application: Specifically engineered for blind-hole tapping projects where clear chip removal and consistent thread quality matter.
This combination—powder-metal strength, TiCN wear resistance, and an optimized spiral flute—delivers smoother cutting action, fewer tool changes, and reliable thread integrity in challenging blind-hole applications. Ideal for precision manufacturing, automotive components, and aerospace-related parts where tight tolerances and durable performance are essential.
