Wiseman Threading Tools Metric Fine HSS Hand Tap Set ISO529 - M35x1.5

The Wiseman Threading Tools Metric Fine HSS Hand Tap Set ISO529 - M35x1.5 is your go-to kit for clean, precise internal threads in metal. Built for reliability, these high speed steel ground taps are uncoated for straightforward cutting and a true, chip-friendly engagement with your workpiece. Engineered to ISO 529 specifications, they deliver the exact metric fine thread you need, with a right-hand thread orientation that matches standard threading tasks.

What makes this set stand out:

• Material and finish: High-speed steel (HSS) ground taps offer durability and a sharp cutting edge, designed to withstand repeated use across common machinable metals. The uncoated finish keeps the tapping action simple and predictable, ideal for maintenance work and fabrication projects.
• ISO 529 compliance: Every tap in the set adheres to ISO 529 dimensions, ensuring consistent thread profiles and compatibility with M35x1.5 internal threads found in many metric-equipped parts and components.
• Metric fine thread, M35x1.5: This designation provides a smaller pitch and tighter fit, enabling strong, accurate fastenings in thin-walled or precision assemblies where a coarser thread would risk stripping or play.
• Right-hand threading: Optimized for standard assembly methods, making installation straightforward in typical manufacturing and repair scenarios.
• Lead variety for dependable tapping: Includes taper lead, second (plug) lead, and bottom lead taps. This combination guides the thread from a gentle starting cut through full-thread engagement, delivering clean, consistent threads from the first pass.
• Versatile applications: Suitable for a range of metals, including machinable steels, cast iron, aluminum, and many alloys used in automotive, mechanical, and DIY projects. Use with a tap wrench and cutting fluid to maximize life and finish.
• Practical, shop-ready design: The set is compact and focused on delivering reliable internal threads where they’re most needed—repair jobs, new component fabrication, or rebuilding worn threads.

How to get the best results: start with a light lubrication and a gentle feed to prevent chatter, align the tap square to the workpiece, and back off periodically to clear chips. Move through the taper, plug, and bottom taps in sequence to build the thread depth cleanly and accurately. When the job is done, wipe away chips and inspect the thread for smooth engagement with a matching bolt or insert to verify fit.

Ideal for hobbyists and professionals alike, this Wiseman Metric Fine HSS Hand Tap Set is designed to empower you to create robust internal threads with confidence and precision. Whether you’re repairing damaged threads or machining new components, rely on the proven accuracy of ISO529-compliant taps and the consistent cutting action of uncoated HSS tools.
