The OSG Metric Spiral Flute Threading Tap is a precision tapping tool designed for creating M12 x 1.75 threads in blind holes, delivering consistent, high-quality results in metalworking operations. Built for machinists who demand durability and reliable performance, it excels in tight, hard-to-reach spaces where clean threads are critical.

• Size and pitch: M12 x 1.75 threading tap, optimized specifically for blind-hole applications.
• Material: HSS-E (high-speed steel with cobalt) for enhanced hot hardness and wear resistance in demanding cuts.
• Coating: Steam Oxide Coated Plus to improve wear protection and corrosion resistance during extended use.
• Flute design: Metric spiral flute engineered for efficient chip evacuation in blind holes, reducing clogging and re-cutting.
• Application: Ideal for precise thread formation in metal parts where access is limited and reliability matters.

With this tap, you gain durable cutting performance and stable thread quality across production runs. The cobalt-infused HSS-E construction withstands higher cutting temperatures, helping maintain thread accuracy and extending tool life. The spiral flute design facilitates continuous chip removal, minimizing dwell time in deep or obstructed blind holes and lowering the risk of tool breakage. Steam Oxide Coated Plus further protects the cutting edges, supporting consistent results in tough materials and busy shop environments.
