Meet the Wiseman Threading Tools Second Lead Metric HSS Tap Left Hand - M22x2, a precision internal tapping tool built for reliability in real-world workshops. Crafted from high-speed steel and ground for accuracy, this uncoated tap is designed to cut left-hand threads with a robust, general-purpose performance. ISO 529-compliant dimensions ensure predictable results across standard metric threads, making it a dependable choice for everyday machining tasks.

• Left-hand threading capability — perfect for internal left-handed threads or assemblies that require reverse-threaded components.
• Second lead (two-start) geometry — delivers faster material removal per rotation and smoother chip evacuation, boosting efficiency on through-holes and reducing cutting torque.
• High-speed steel, ground finish, uncoated — balanced hardness and toughness for a wide range of workpieces, with cutting fluid enhancing performance where needed.
• Size and standard — M22x2 fits standard metric internal threads; ISO 529 alignment ensures compatibility with common hosts and mating parts.
• General purpose versatility — well-suited for mild steel, cast iron, aluminum, and other common alloys in fabrication, repair projects, or prototyping.

Practical guidance for best results: select the correct drill/tap combination per ISO 529 drill-size recommendations, apply a quality cutting fluid to minimize heat and prolong tool life, and maintain a steady, perpendicular approach to guarantee straight, evenly spaced threads. Start the tap gently, advance with controlled pressure, and back off periodically to break chips. After tapping, inspect engagement with the mating bolt to confirm a clean, precise fit.

Whether you're retrofitting equipment, repairing a left-hand threaded assembly, or pursuing specialized builds, this Wiseman HSS tap delivers consistent, dependable performance. It’s a proven choice for machinists who value accuracy, durability, and efficiency in metric M22x2 threading.
