The Wiseman Threading Tools Second Lead Metric HSS Tap Right Hand - M30x2 is a precision ground, high-speed steel tap designed for efficient metric thread cutting in a wide range of metals. Uncoated and ready for general-purpose use, this tap adheres to ISO 529 dimensions, ensuring reliable compatibility with standard M30x2 holes.

What makes this tap special

• Second lead (two-start) design: Two thread starts engage simultaneously, delivering faster hole threading and reduced tapping cycle times without compromising thread quality.
• Right-hand thread: Ideal for conventional machining setups where standard rotation creates the thread direction you expect.
• Metric precision, M30x2: Large-diameter, fine-pitched thread suited for structural, mechanical, and assembly applications where robust fasteners are required.
• High-speed steel, ground finish: Offers dependable sharpness and torque control for clean, accurate threads across common metals such as steel, aluminum, and brass.
• ISO 529 compliant: Ensures consistency with other standard taps and fits seamlessly into established machining workflows.

Ideal applications

• Repairing damaged threads in machinery housings, brackets, and enclosures where M30x2 fasteners are standard.
• Fabrication and maintenance work in automotive, aerospace, and CNC projects that require reliable, fast thread creation.
• Prototyping and production environments where cycle time matters and you need consistent, repeatable results.

How to use for best results

• Choose the correct pilot hole size for M30x2 based on a standard tapping chart and the two-start lead; maintain perpendicular alignment to the workpiece.
• Apply a suitable cutting fluid or coolant to minimize heat, extend tool life, and improve chip evacuation.
• Make gradual plunges with steady, even pressure; back out occasionally to break chips and prevent binding.
• Use a quality tap wrench or a tapping-equipped machine to maintain precise alignment and consistent torque.

With its robust construction, precise ISO-compliant geometry, and faster threading capability, this Wiseman M30x2 HSS tap is a dependable choice for professionals who demand reliable, repeatable threads in a variety of materials. Whether you're rebuilding a unit, fabricating a new component, or conducting routine maintenance, this tap delivers the performance you need to get the job done right.
