The OSG Threading Tap Metric A-LT-Spiral Point is a high-performance tapping solution designed for through-hole threading in metric sizes. Built for machinists and engineers who value precision and durability, it delivers clean, accurate threads with extended tool life.
- Size & Thread: Metric M2.5 x 0.45 through-hole tapping per DIN371.
- Material: Powder metal construction for exceptional strength and wear resistance.
- Coating: TiCN coating reduces friction, enhances chip flow, and supports higher cutting speeds.
- Design: Spiral Point (A-LT) geometry pushes chips forward for efficient evacuation and pristine thread profiles in through-holes.
- Orientation: Right-hand thread compatibility with standard machining setups.
- Standards: DIN371-compliant through-hole tapping to meet common industry specifications.
- Applications: Suitable for a broad range of materials, ideal for production runs and precise prototyping.
Using this tap yields consistent thread quality with tight tolerances, even in tougher materials. The TiCN coating minimizes wear and heat, enabling higher speeds and longer tool life, while the spiral-point design reduces chip packing and ensures smooth, reliable threading in through-holes. This combination supports faster cycle times, improved part accuracy, and dependable performance across demanding tapping tasks.
