Wiseman’s Metric Fine HSS Hand Tap Set, designed to deliver precise, repeatable threads in metric sizes, is the reliable backbone of any metalworking toolbox. Made from high-speed steel and ground to tight tolerances, these taps provide clean, accurate cuts even when you’re working with harder metals. The set follows ISO 529 dimensions, ensuring your M18x2 holes and threads stay consistent with industry standards, no matter which brand of tap you pair it with.

• Three-lead geometry for smooth finishing — taper lead to start cleanly, second (plug) lead to continue cutting, and bottoming lead to finish the thread to full depth in a single setup.
• Right-hand metric threading — ideal for most general-purpose applications where standard M18x2 threads are required.
• Uncoated HSS, general purpose — optimized for everyday tapping in steel, cast iron, and non-ferrous metals when used with proper cutting fluid.

This tapping set is perfectly suited for fabrication, repair, and maintenance work. Use it to create new threads in brackets, housings, and components, or to restore damaged threads in machinery where metric precision matters. It’s a practical choice for workshops, maintenance teams, and DIY enthusiasts who demand dependable performance without hunting for multiple taps—the three-lead geometry covers starting, mid-cutting, and finishing in one compact set.

Pro tips for best results: ensure your pilot hole matches the recommended size for M18x2 threads, always use a quality cutting fluid, and keep the tap perpendicular to the workpiece. Start with the taper tap to establish the groove, progress with the plug tap, and finish with the bottoming tap if full-depth threads are needed. Turn with steady, even pressure and back off slightly to break chips as you advance.

Wiseman Threading Tools deliver consistent, trustworthy performance for metric fine threading projects—so you can tackle threaded assemblies with confidence.
