Meet the Wiseman Threading Tools Second Lead Metric HSS Tap Right Hand - M24x1, a purpose-built threading tap designed for speed, precision, and reliability in metalworking projects. Forged from high-speed steel and ground for accuracy, this uncoated tap delivers clean, consistent threads in a range of metals while standing up to frequent use in both shop and on-site maintenance tasks. It follows ISO 529 dimensions and features a right-hand thread with second lead (USA plug lead) for efficient, chip-friendly tapping.

• Material and finish: High-speed steel (HSS), ground and uncoated for versatile performance across steel, aluminum, stainless, and cast iron. The uncoated finish provides predictable cutting action and easy re-sharpening when needed.
• Threading details: Right-hand metric thread M24x1 with a second lead (two-start) design. This means faster thread formation and improved chip evacuation compared to a standard single-lead tap.
• Standards and compatibility: ISO 529 compliant, ensuring correct hole size and thread form for reliable mating with standard M24x1 fasteners and inserts.
• Shank and tooling: Square drive shank compatible with common tap wrenches for solid, repeatable engagement. Ideal for handheld tapping and machine-assisted operations alike.
• Ideal applications: Through-hole tapping in metalworking projects, maintenance on machinery, and fabrication tasks where dependable metric threads are required. Works well on mild steel, cast iron, aluminum, and other common alloys with appropriate cutting fluid.
• Usage guidance: Apply a light cutting oil to reduce heat, maintain clean threads, and extend tool life. Drill the proper pilot hole per ISO 529 guidelines and rotate smoothly—avoid forcing the tap, especially in hard materials.

Why choose this Wiseman HSS tap? It combines a robust HSS core with a thoughtful two-start lead that balances speed and control. For professionals who routinely cut M24x1 threads, this tool delivers dependable performance, predictable results, and longevity in a single, compact instrument.
