Meet the Wiseman Threading Tools Metric Fine HSS Hand Tap Set ISO529 - M15x1.5, a precise, reliable solution for creating or repairing metric threads in metal. Crafted for everyday workshop use, this set is designed to deliver clean, accurate threads with every cut, thanks to properly ground high-speed steel and a thoughtful, ISO-standardized design.

• High-speed steel (HSS) with ground threading for smooth cutting, sharp starts, and improved durability under typical tapping workloads.
• Uncoated finish to work effectively with standard cutting fluids and to produce crisp thread profiles without interference from coatings.
• ISO 529 dimensions ensure compatibility with standard metric fasteners and mating parts, reducing guesswork in the workshop.
• Right-hand thread orientation for conventional threading tasks across metal projects.
• Taper, second (plug), and bottom taps included in the set to progressively form and finish the full thread length with consistency.
• Metric fine thread, M15x1.5 provides a finer pitch for precise engagement and stronger, more refined fastener fitment.

Ideal applications include repairing damaged threads, creating new metric holes in mild steel, aluminum, and other common metals, and supporting accurate fastener assembly in automotive, fabrication, and workshop projects. This tap set pairs well with a standard tap wrench and good tapping fluid to minimize heat and maximize tool life.

• Great for hobbyists and professional mechanics who demand dependable, repeatable results.
• Suitable for projects requiring precise metric threads where fit and finish matter.

Pro tips for best results:

• Secure your workpiece and align the tap squarely to the hole to prevent thread misalignment.
• Lubricate with cutting oil or tapping fluid to reduce friction and chip buildup.
• Turn slowly with steady pressure; back off periodically to clear chips from the flutes.
• After use, clean and dry the taps before storing them in a dry environment to protect edge integrity.
