Wiseman Threading Tools Metric Fine HSS Hand Tap Set ISO529 - M80x2

Master reliable, precise internal threading with the Wiseman Threading Tools Metric Fine HSS Hand Tap Set ISO529 - M80x2. Built for serious metalwork, this set pairs high-speed steel ground taps with a thoughtfully staged cutting sequence to deliver clean, accurate threads in a variety of materials.

What makes this set stand out

• ISO 529 compliant geometry ensures consistent thread profile across the taper, second, and bottom taps, so your holes thread true every time.
• Metric M80x2 size provides a robust, widely applicable thread for larger components, with a 2 mm pitch for fine, precise threading.
• Right-hand threading matches the vast majority of standard applications, from machinery housings to automotive parts.
• Three-lead progression—taper, second, and bottom taps—gives you a controlled, incremental cutting action that reduces chatter and helps you reach full thread depth with confidence.
• High-speed steel, ground finish, uncoated for versatile, general-purpose use. The precision grind delivers sharp cutting edges for faster material removal and cleaner threads.
• Compatibility with hand tooling designed for use with a standard tap wrench and cutting fluid, making it ideal for workshops, garages, and hobbyist setups alike.

Where you’ll use it

• Repairing or fabricating threaded holes in steel, cast iron, and many aluminum components
• Creating new internal threads in equipment housings, brackets, and enclosures
• Repair or retrofits in automotive, motorcycle, and machinery projects where robust, metric threads are required

Practical use tips

• Drill the pilot hole to the material’s recommended size for M80x2 before tapping, then lubricate generously with a suitable cutting fluid to ease cutting and extend tap life.
• Begin with the taper tap, advance gradually, and back off periodically to break and clear chips. Move to the second tap, then finish with the bottom tap for full thread depth.
• Keep the tap perpendicular to the workpiece to avoid skewed threads, and wipe away chips frequently to prevent binding.
• After tapping, clean the hole and inspect the thread fit with a compatible bolt or plug gauge to ensure proper engagement.
