OSG Threading Taps Metric A-Spiral Flute are precision taps designed for metric blind-hole threading. They deliver reliable oversize threads for M12 x 1.75 holes in demanding manufacturing environments.

• Flute Design: A‑spiral flute promotes efficient chip evacuation, reducing chip packing in blind holes and lowering the risk of breakage during tapping.
• Material: Powder metal construction enhances strength and wear resistance for long tool life in tough machining conditions.
• Coating: TiCN coating increases surface hardness and minimizes friction for smoother cutting and extended tool life at high speeds.
• Oversize Tolerance: +0.1 mm oversize to help achieve consistent thread engagement in tight or close-tolerance blind-hole applications.
• Size & Thread: M12 x 1.75 with right-hand threads, suitable for standard metric screw paths in common assemblies.
• Right-Hand Thread: Right‑hand orientation aligns with conventional machining practices for widespread compatibility.
• DIN Standard: DIN 376 compliant, ensuring standardization and interchangeability in professional shops.
• Application Focus: Specifically designed for precision tapping in metric blind holes where clean, reliable threads are essential.

This tap combination addresses common tapping challenges: it resists wear under repetitive use, maintains accurate thread dimensions with its deliberate oversize tolerance, and stays cool and fast thanks to the TiCN coating. The spiral flute aids chip removal in blind holes, helping you maintain steady feeds and finishes, while the powder-metal body provides a robust, durable tool for automotive, machinery, and precision engineering tasks. Whether you’re finishing critical assemblies or performing routine maintenance, this tap is built to deliver consistent results with minimal rework.
