The Wiseman Threading Tools Second Lead Metric HSS Tap Right Hand - M8x1.25 is a precision, uncoated tapping solution built for dependable metalworking performance.Ground from high-speed steel and finished for general purpose use, this tap delivers consistent, accurate internal threads that align with ISO 529 dimensions. The right-hand thread and second lead (two-start) design translate into smoother cutting action and faster thread advancement, helping you complete holes with fewer passes and reduced tapping time.

• Material and finish: High-speed steel ground tooling for durable cutting edges. Uncoated finish keeps heat transfer predictable and is ideal when paired with standard cutting fluids common in metalworking.
• Thread specification: Metric M8 x 1.25 with a right-hand thread, conforming to ISO 529 for compatibility with standard fasteners and threaded holes.
• Lead design: Second lead (two-start) configuration creates more lead per revolution, enabling faster hole threading without sacrificing thread quality in suitable materials.
• Versatility: Suitable for general purpose tapping in mild steel, aluminum, brass, and other common metals when used with proper lubrication and a steady tapping technique.
• Compatibility and use: Optimized for hand tapping with a tap wrench or machine tapping setups that accommodate standard taps. Maintain alignment to prevent cross-threading and prolong tool life.
• Quality and precision: Engineered to deliver clean thread profiles with consistent pitch. ISO-compliant dimensions ensure reliable fitment with compatible fasteners and components.

This tap is ideal for workshop machinists, fabricators, and DIY enthusiasts who need reliable M8x1.25 threads without complex tooling. Use it to create new threads in hardened or unhardened metals with appropriate lubrication, or to rework holes in assemblies where precise, repeatable threading matters. To maximize longevity, clean chips frequently, avoid forcing the tool, and store after use in a protective environment.
