Wiseman Threading Tools Metric Fine HSS Hand Tap Set ISO529 - M7x1.25

Achieve precise, repeatable threads with the Wiseman Metric Fine HSS Hand Tap Set. Designed for manual tapping, this set delivers clean, accurate M7x1.25 threads that meet ISO529 standards. Built from high-speed steel and ground to sharp, consistent cutting edges, these taps are uncoated for versatile performance across a wide range of common metals.

• ISO 529 compliant metric fine threading – reliable, standardized dimensions that ensure compatibility with fasteners and nuts designed to the same specification.
• Right-hand thread – the standard configuration for most everyday machining and assembly tasks.
• Three-lead precision sequence – taper (start), second (plug), and bottoming taps provide a complete threading progression from initial groove to full thread depth, suitable for both through-holes and blind holes.
• Uncoated HSS, general purpose – durable high-speed steel with a versatile, no-friction cutting edge that performs well on steel, aluminum, brass, and other common materials.
• Hand-tap efficiency – optimized for manual operation, enabling clean cuts with controlled force and minimal chatter, ideal for hobbyists, DIY enthusiasts, and professional workshops alike.

Use cases and ideal applications

• Repair or recreate precise M7x1.25 threads in small to mid-size fasteners for machinery, fixtures, or automotive projects.
• Prototype or customize components in a home shop or professional environment where metric fine threads are required.
• Fabricate or refurbish parts that demand durable, accurately threaded connections without relying on power tapping.

Practical guidance for best results

• Always apply an appropriate tapping fluid or cutting oil to reduce friction, extend tool life, and improve thread finish.
• Begin with the taper tap to establish the thread groove, then progress to the plug tap, and finish with the bottoming tap if you need full-depth threads in blind holes.
• Maintain proper alignment to prevent cross-threading; advance slowly and back off after each complete turn to clear chips.
• After use, clean the taps, apply a light oil, and store in a dry environment to preserve sharpness and avoid corrosion.
