The Wiseman Threading Tools Second Lead Metric HSS Tap Right Hand - M17x1 is a precision-made threading tap built for dependable metric threads in metalworking projects. Crafted from high-speed steel and ground for accuracy, this tap delivers clean, consistent cuts with every pass.

Key features and benefits

• Material and finish: high-speed steel (HSS) ground threading tap, uncoated for versatile use across a range of metals and cutting fluids.
• Thread specifications: M17x1 metric thread with a right-hand orientation, designed to form standard machine threads in through-holes and components.
• Second lead design: a double-start (second lead) configuration that enables faster thread formation, reducing tapping time and improving throughput on projects with larger or deeper holes.
• ISO standard: aligns with ISO 529 dimensions, ensuring compatibility with standard metric taps and predictable engagement in common fabrication work.
• USA plug lead: configured to fit typical workshop tapping setups, making it ready for use in standard tool cabinets and machines.
• Chip control and durability: precision-ground flutes promote efficient chip evacuation and steady cutting action, helping to minimize tap breakage and extend life in routine tapping jobs.

What this tap is ideal for

• Through-holes in steel, cast iron, and aluminum where metric threading is required.
• Prototype builds, repair work, and general fabrication where quick, reliable M17x1 threads are needed.
• Applications that benefit from faster tapping cycles without sacrificing thread integrity, thanks to the second-lead design.

How to get the best results

1. Use a properly sized pilot hole according to standard tapping practices for M17x1 threads, and keep the hole clean and free of chips.
2. Apply a light cutting fluid or oil to reduce friction and extend tap life during tapping.
3. Support the workpiece with a tap wrench or drilling/tapping machine to apply steady, even pressure and prevent misalignment.
4. Periodically back out the tap to break chips and prevent binding, especially in tougher metals.
5. Inspect the formed threads for consistent pitch and depth, and remove the tap carefully once the thread is complete.

With the Wiseman Second Lead Metric HSS Tap, you gain a reliable, efficient solution for creating precise M17x1 threads. Its combination of robust HSS, ISO 529 compliance, and a double-start design sets it apart for workshops that demand speed without compromising thread quality.
