Wiseman Threading Tools Second Lead Metric HSS Tap Right Hand - M80x2 is a rugged, high-speed steel ground tap built for dependable metric threading in metalworking projects. The uncoated design keeps cutting edges sharp for steady performance across steel, stainless, and other alloys, delivering clean, accurate threads with every pass. Its right-hand, second-lead configuration is optimized for faster through-hole threading, helping you finish jobs sooner without sacrificing thread quality.

What makes this Wiseman tap stand out

• Second lead, two-start design: The two-start configuration shares the cutting load, accelerates material removal, and reduces tapping time for long through-holes, while still delivering the precise pitch and fit you expect from a metric M80x2 tap.
• High-speed steel, ground finish: The HSS ground substrate provides durable cutting edges and heat resistance under typical tapping conditions, helping extend tool life when used with proper cutting fluid.
• Uncoated, general-purpose: No coating means consistent chip formation and predictable performance across a range of materials, making it a reliable workhorse for everyday tapping tasks.
• ISO 529 compliant dimensions: Designed to meet international standards for metric threads, ensuring compatibility with taps, taps wrenches, and threaded components that follow ISO specifications.
• Right-hand thread operation: The standard threading direction for most common applications, ideal for factory, shop, and home machining setups.
• Square-drive end: The square shank is compatible with most common tap wrenches and handles, providing solid engagement and controlled cutting leverage.

Ideal use cases and applications

• Tapping large-diameter metric holes in steel, aluminum, and other alloys where fast, reliable threads are needed.
• Repair work or fabrication projects requiring robust, durable threading tools for repeated use in maintenance shops and machine shops.
• Through-holes where efficient material removal is a priority, thanks to the second-lead design that speeds the threading process.
• Projects following ISO 529 standards where consistent thread pitch and dimensions are crucial for assembly accuracy.

Practical tips for best results

1. Use a quality cutting fluid or tapping oil to reduce heat, improve chip flow, and extend tap life.
2. Drill the correct pilot hole size per ISO guidelines for M80x2 to ensure clean cutting and optimal thread engagement.
3. Begin tap insertion with steady, light pressure and maintain a consistent feed rate; back off periodically to break chips and prevent binding.
4. Back the tap out occasionally during deep holes to clear chips and prevent tap breakage.
5. Clean and lightly oil the tap after use to preserve edge sharpness and prevent corrosion between jobs.
