The Wiseman Threading Tools Second Lead Metric HSS Tap Left Hand - M30x2 is built for precision tapping where speed and reliability matter. This high-speed steel ground tap is purposefully unf coated and designed to deliver clean, accurate threads in a variety of metals. With ISO 529 dimensions and a true left-hand thread, it’s the ideal choice for specialized machining tasks that require reverse threading or quick removal of threads when needed.

• Left-hand thread: engineered for reverse threading applications, adjustments, or maintenance tasks where conventional right-hand taps won’t suffice.
• Second lead: a double-feed pitch that accelerates the tapping process, reducing cycle time on deeper holes and enabling faster finishing—even on softer materials.
• HSS ground, uncoated: a robust, sharp cutting edge that yields consistent thread profiles while handling heat and wear under typical shop conditions.
• M30x2 size: metric coarse-sizer compatibility with precise pitch control, suitable for components and assemblies that specify 30 mm major diameter with a 2 mm thread pitch.
• ISO 529 compliant: ensures predictable results and compatibility with standard threading charts and industry norms.
• USA plug lead designation: designed to align with common US manufacturing setups, helping you integrate this tap into existing workflows with minimal adaptation.

Designed for pro shops, hobbyists, and any workspace that relies on accurate, repeatable threading, this left-hand, second-lead tap shines in repair work, chassis fabrication, and precision builds. Use with proper lubrication to maximize tool life and achieve the cleanest possible threads, especially when threading into tougher metals or deeper holes.

Why choose this Wiseman tap? It combines aggressive cutting geometry with a refined ground finish to minimize cutting forces while delivering tight, true threads. Its metric M30x2 profile, coupled with a left-hand lead, makes it a specialized tool for scenarios where reverse threading or quick disengagement is critical.

Practical tip: start the thread with a light hand and steady pressure, then advance gradually while maintaining consistent lubrication. For best results, pair this tap with a matching threaded nut or insert and a quality tapping fluid to reduce heat buildup and extend tool life in continuous production runs.
