Meet the Wiseman Threading Tools Second Lead Metric HSS Tap Right Hand - M33x2, a precision threading solution designed for reliable, repeatable internal threads in metalworking projects. Built for professionals and serious hobbyists, this tap combines durability, accuracy, and practical design to keep your holes cleanly threaded with minimal fuss.

This is a high-speed steel (HSS) ground thread tap, uncoated for broad compatibility with a range of cutting fluids and materials. It conforms to ISO 529 dimensions, ensuring consistent thread form and compatibility with standard nuts and inserts when paired with the correct pilot drill. The right-hand thread orientation makes it ideal for normal threading tasks used in most mechanical assemblies.

The second lead (USA plug lead) geometry is a key performance enhancer. By beginning the cut with a higher lead, it reduces overall torque and improves chip evacuation on deeper holes, so you can tap longer threads with less effort. This translates to faster cycles in production work and smoother operation during repair jobs or prototype builds.

Ideal for a variety of metals, the Wiseman M33x2 tap is well suited for aluminum, mild steel, brass, and similar substrates. Its robust HSS construction delivers dependable edge retention and a precise thread profile, helping you achieve clean, accurate threads that tighten evenly under load. The uncoated finish makes it a versatile choice when you’re applying cutting fluids, working in wet environments, or preferring a straightforward coating-free tool path.
