Meet the Wiseman Metric Fine HSS Hand Tap Set—ISO 529 compliant M12x1.5. Built for precision threading in metalworking, this three-piece hand tap set delivers clean, accurate internal threads with dependable performance in a compact, easy-to-use package. The taps are made from high-speed steel and ground for true alignment and smooth cutting, uncoated to provide consistent material contact and chip flow across a range of metals.

What’s included and how it works

• Taper lead tap begins the threading process, easing entry and aligning the hole for subsequent cuts.
• Second lead tap continues cutting the thread with controlled progression, building the thread depth with stability.
• Bottoming (bottom) lead tap finishes the thread to the bottom of blind holes, producing a full-depth M12x1.5 thread.

Key features that matter for your project

• set in M12x1.5, ideal for precise fasteners and compact assemblies where a finer pitch is required.
• orientation provides predictable turning direction and compatibility with standard components.
• ensure compatibility with standard taps and chucks, so replacements and accessories align across brands.
• offer rigidity, wear resistance, and sharp cutting edges for repeated use in steel, cast iron, and other common metals.
• supports robust metal-to-metal cutting with straightforward lubrication and reliable heat dissipation in typical workshop conditions.

Ideal applications and use cases

Designed for workshops, machine shops, and serious hobbyists, this Wiseman tap set excels in:

• Creating internal threads in mild steel, aluminum, and copper for bolts and fasteners with M12x1.5 compatibility.
• Repairing stripped or damaged threads in repair projects where a precise, standard-thread fit is essential.
• Prototyping and small-batch production where consistent, repeatable tapping results matter.
• Enclosures, brackets, and automotive components that require a reliable metric fine-thread connection.

Practical usage tips for best results

• Match the drill size to ISO 529 guidance for M12x1.5 fine pitch to ensure proper thread engagement and chip clearance.
• Use a light cutting oil or tapping fluid to reduce friction, prolong tool life, and improve finish quality.
• Turn the taps gradually with a tap wrench, applying steady pressure, then back off every few degrees to break chips and prevent binding.
• Clean the threads after tapping and inspect with a suitable thread gauge to confirm accuracy before assembly.
