Crafted from high-speed steel and ground for accuracy, this uncoated tap is built for everyday metalworking tasks and engineered to ISO 529 standards.

Key features

• Left-hand thread: Specifically designed to cut threads that tighten counterclockwise, ideal for reversing loads or specialized assemblies.
• Metric size: M22x2.5 with bottom lead, enabling reliable entry and smoother chip flow in deeper holes.
• Bottom lead: A starting lead that reduces the chance of thread wobble and helps initiate the cut cleanly, especially in blind holes.
• Material and finish: High speed steel (HSS), ground to tight tolerances, uncoated for broad compatibility and easy re-sharpening or coating if needed.
• Standards: ISO 529 dimensions ensure compatibility with standard female threads and tooling in metric systems.
• General purpose use: A versatile tapping solution for steel, aluminum, cast iron and other common metals in workshops and production lines.
