Meet the OSG Metric Spiral Flute Threading Tap in M12 x 1.75—a high-performance tool designed for machinists who demand precise, durable threads in blind-hole applications. Built from HSS-E cobalt and finished with a Titanium Nitride (TIN) coating, this tap combines hardness, wear resistance, and reliable performance for demanding metalworking tasks.

• Size & Pitch: M12 x 1.75 — metric fine-pitch threading for accurate, standard-compatible screws and bolts
• Material: HSS-E cobalt alloy—enhanced toughness and heat resistance for tough tapping jobs
• Coating: Titanium Nitride (TIN) coating—reduces friction, extends tool life, and aids wear resistance
• Flute Design: Spiral flute optimized for efficient chip evacuation in blind holes, minimizing clogging and tapping torque
• Application: Specifically suited for blind-hole threading in metal components where access is limited

This tap delivers consistent thread quality and longer tool life thanks to the combination of cobalt-strengthened steel and a protective TiN coating. The spiral flute geometry ensures smooth chip removal, which is especially beneficial in confined blind-hole environments. Ideal for production and repair work alike, it helps maintain precision in critical assemblies and reduces downtime due to worn or mis-tapped holes.
