The Wiseman Threading Tools Taper Lead Metric HSS Tap in M22x1.5 is built to cut precise, reliable left-handed threads with clean, consistent results. Designed for general purpose tapping, this uncoated high-speed steel tool combines durability with ease of use, making it a dependable addition to any workshop or production line.

Why this taper lead left-hand tap stands out

• Left-hand threading capability—tailored to create reverse-rotation threads that tighten counterclockwise, ideal for applications where reverse torque is required to prevent loosening.
• Taper lead design—the gradual entry reduces the risk of cross-threading, delivering smoother starts and a cleaner thread from the very first cut.
• Uncoated HSS construction—ground, high-speed steel provides dependable hardness and edge retention for routine tapping tasks, with the versatility to use your preferred cutting fluids.
• ISO 529 compliant dimensions—specifically matched to ISO standard thread forms, ensuring predictable performance and compatibility with standard components in the M22x1.5 size.
• Metric precision—M22x1.5 taps are a common specification in machinery, automotive, and maintenance environments, making this tool a practical choice for both repairs and production work.

Ideal use cases

• Creating or repairing left-handed threads in mechanical assemblies where reverse torque is required to prevent loosening.
• Maintenance and repair tasks in automotive, industrial equipment, and machinery where M22x1.5 threads are specified.
• Prototype and production environments that benefit from a reliable, general‑purpose left-hand tap with a forgiving entry.

How to get the best results

1. Use a compatible tap drill size and apply a quality cutting fluid to reduce heat and extend tap life (consult ISO 529 guidelines for the recommended pilot hole).
2. Ensure your workpiece is properly supported and aligned to prevent thread distortion.
3. Turn the tap in the reverse direction (as required for left-hand threads) with steady, even pressure; advance slightly, then back off to clear chips regularly.
4. Finish with a light pass to clean the threads and remove any burrs, then inspect the thread fit with a suitable go/no-go gauge.

Care, storage, and longevity

• Clean the tap after use and wipe away any cutting fluid or debris.
• Lightly oil or store in a dry environment to prevent corrosion on the uncoated surface.
• Keep out of impact-heavy environments to preserve edge geometry and overall accuracy.

Designed for professionals who value precision and reliability, the Wiseman Threading Tools Taper Lead Metric HSS Tap delivers consistent performance when cutting M22x1.5 left-hand threads. This tap is a practical, long‑term addition to any toolkit dedicated to accurate threading, maintenance, and repair work.
