Discover the Wiseman Threading Tools Taper Lead Metric HSS Tap Left Hand - M18x2, a precision internal-threading solution built for reliability in metric applications. Ground high-speed steel, uncoated for versatility, and engineered to ISO 529 dimensions, this left-hand tap delivers clean, accurate cuts every time you need a reverse-threaded connection.

• Left-hand threading efficiency: Specifically designed to create internal left-handed threads, making it ideal for assemblies that rely on reverse-fasteners to resist loosening under vibration or torque.
• Taper lead for smoother starts: The taper lead reduces starting torque and helps prevent cross‑threading, protecting both the workpiece and the tap during initial engagement.
• Metric precision: M18x2 sizing aligns with standard metric fasteners and components; ISO 529 compliant design ensures consistent threads across compatible parts and tools.
• Durable HSS ground finish: High-speed steel with a carefully ground geometry gives sharp cutting edges, predictable performance, and good edge life on common metals such as steel and cast iron. Uncoated finish keeps it simple to inspect wear and resharpen if needed.
• General purpose, purpose-built: While suited for broad threading tasks, its left-hand configuration and taper lead make it an excellent choice for repair work or new builds that require controlled, reliable reverse-threaded inserts.

Practical use and tips:

• Perfect for fabricators and shop technicians tackling internal left-hand threads in metal housings, fittings, and components where reverse engagement is essential.
• Pair with appropriate cutting fluid and steady, controlled feed; let the taper lead do the initial cutting to minimize skip and ensure a pristine thread profile.
• Verify thread quality with a metric thread gauge after cutting, ensuring the M18x2 left-hand thread meets your tolerance needs.
