The OSG Metric Fine A-Spiral Flute Threading Tap is engineered for precise, high-quality threading in metric blind holes. Ideal for professional machinists, fabricators, and maintenance technicians, it delivers reliable performance in tight cavities with a focus on durability and accuracy.

• Threading type: Metric fine thread, M18 x 1.5, right-hand orientation for standard assembly needs
• A‑Spiral flute design: Optimized for efficient chip evacuation in blind holes, reducing chip packing and improving cut quality
• Material: Powder metal body for enhanced wear resistance and extended tool life in demanding workloads
• Coating: TiCN coating increases surface hardness, lowers friction, and supports higher cutting speeds and temperatures
• Standards: DIN 374 compliant, ensuring compatibility with common metric tapping practices
• Application: Suitable for fine-thread tapping in metalwork where access ends at a blind depth, delivering clean, accurate threads

This tap pairings a robust build with smart geometry to support consistent thread formation, especially where tight tolerances and reliable hole integrity matter. The TiCN coating helps maintain performance over longer tool life, while the powder metal substrate stands up to wear in repeated use. Whether you’re building precision components, performing repairs, or machining automotive hardware, this tap is designed to help you achieve true, machine-fit threads with less downtime and fewer reworks.
