The Wiseman Threading Tools metric fine HSS hand tap set is a purpose-built solution for creating and repairing precise M17x1 threads with confidence. Crafted from high-speed steel and ground for a true, clean thread profile, this uncoated tapping kit delivers reliable performance across a range of common metals. Conforming to ISO 529 standards, it ensures consistent thread pitch and fit for metric components, making it a trusted choice for machinists, hobbyists, and repair projects alike.

What makes this set stand out:

• Metric fine threading: M17x1 right-hand threads provide a precise, robust connection for assemblies where fine pitch matters.
• ISO 529 compliant: Designed to industry-standard dimensions, ensuring compatibility with standard taps, dies, and components.
• HSS ground taps: High-speed steel delivers strong cutting edges and accurate thread formation, reducing chatter and ensuring clean holes.
• Uncoated for versatility: An uncoated finish supports consistent cutting performance with a variety of lubricants and materials.
• Starting to finishing taps: The set covers the threading progression from initial engagement to final, accurate threads through taper, plug (second), and bottom leads.

Ideal use cases: - Repair or recreate M17x1 threaded holes in steel, cast iron, and aluminum components with dependable results. - Build or restore critical assemblies where precise metric threads ensure proper alignment and load transfer. - Hand tapping projects in machine shops or DIY workshops where a portable, wrench-friendly solution is preferred over powered tapping.

Practical guidance for best results: - Lubricate generously with appropriate tapping fluid or light oil to reduce friction and chip buildup during cutting.

• Align taps carefully with the hole to maintain perpendicularity and prevent thread damage.
• Begin with a light touch on the taper lead, then progressively advance through the second and bottom leads for a clean finish.
• Clear chips frequently by backing off slightly and wiping the threads before continuing.

Whether you’re outfitting a workshop, performing routine maintenance, or tackling a one-off threading task, this Wiseman metric fine HSS hand tap set provides reliable control, repeatable results, and the confidence that comes from using ISO-standard tools designed for precision metalworking.
