The Wiseman Threading Tools Spiral Point Metric HSS Tap, Left Hand - M12x1.75 is a precision ground tapping tool built for durable, reliable left‑hand threads in metal. Crafted from high-speed steel and uncoated for versatile performance, this tap is finished to ISO 529 standards to ensure consistent dimensions and threading quality across your projects.

Key features that set this tap apart:

• Left-hand threading capability — specifically designed to cut reverse threads when your application requires counterclockwise fastener action or reverse‑threaded components, delivering secure and reliable engagement.
• Spiral point (gun nose) design — the forward‑pushing spiral geometry helps evacuate chips and guides the tap into the hole, enabling cleaner starts and faster cycles in both through and blind holes.
• ISO 529 compliant dimensions — engineered to standard metric sizes so you can pair it with compatible tooling and taps in your workshop or production line without fit issues.
• Uncoated high‑speed steel (HSS) — durable, heat‑resistant performance that’s well suited for general purpose threading tasks and easy to resharpen or recondition as needed.
• General‑purpose versatility — suitable for a wide range of metals and thicknesses, making it a reliable choice for maintenance, repair, and fabrication work where left‑hand threads are required.
• Practical for hand and machine tapping — compatible with standard tap wrenches and drill presses, allowing precise control, steady feeds, and consistent thread formation with proper lubrication.

Usage notes: apply a suitable cutting fluid to reduce friction and heat, align the tap precisely with the hole to prevent cross‑threading, and advance with steady pressure while turning in the correct direction for left‑hand threads. Back off periodically to break chips and re‑start smoothly for a clean, accurate M12x1.75 left‑hand thread every time.

With the Wiseman M12x1.75 left‑hand tap, you gain a reliable, purpose‑built tool that delivers consistent thread quality, reduces cycle times, and integrates seamlessly into standard tapping workflows. It’s the thoughtful choice for professionals who demand precision and durability from their threading tools.
