Wiseman Threading Tools Second Lead Metric HSS Tap Left Hand - M14x1.5

Meet the Wiseman Threading Tools Second Lead Metric HSS Tap Left Hand - M14x1.5, a precision-ground tapping solution built for reliability in metalworking tasks that require a left-hand thread. This uncoated, high-speed steel tap follows ISO 529 dimensions and features a second lead for efficient, controlled thread formation. Designed for use with a USA plug lead, it’s ready for standard workshop setups where dependable reverse-threading is needed.

Why choose this Wiseman tap? It delivers consistent thread quality in a compact, versatile package that’s built to endure challenging tapping sessions. The uncoated finish keeps heat management straightforward and makes wear easy to assess, while the left-hand thread capability enables specialized assemblies—from reverse-threaded fasteners to components that require mirrored threading—without swapping tools mid‑process.

• Left-hand thread: Perfect for reverse-rotation fasteners and applications where opposite threading is required.
• Second lead geometry: Enhances material removal and helps initiate threads smoothly, reducing effort on deep or demanding holes.
• Metric precision, M14x1.5: Maintains strict ISO 529 dimensions for reliable, repeatable tapping results.
• Uncoated HSS: Delivers robust performance across a range of metals with straightforward compatibility with cutting fluids.
• USA plug lead: Tailored for common U.S. workshop tapping setups, ensuring easy integration into existing tooling

Ideal for machine shops, repair departments, and field service where left-hand threads matter—think automotive components, valve assemblies, or special fasteners that demand reverse threading. It’s equally valuable for maintenance tasks that require clean, precise threads in soft to medium-hard materials, delivering dependable performance without the need for multiple taps.

How to get the best results: align the tap with the hole axis, apply a light touch to begin thread formation, and use appropriate cutting fluid to manage heat and prolong tool life. Let the tap do the work with steady, even pressure and avoid forcing it through resistance. With the Wiseman tap, you gain a trusted tool that pairs precise geometry with practical, real-world reliability.
