Wiseman Threading Tools Second Lead Metric HSS Tap Right Hand - M13x1.75

Wiseman Threading Tools Second Lead Metric HSS Tap — Right Hand, M13x1.75 is built for professionals who demand precision, speed, and reliability in metalworking. This high-speed steel (HSS) ground thread tap is designed for general-purpose threading tasks, delivering clean, accurate internal threads in a variety of metals with confidence.

• Second lead (two-start) design: The two-start profile cuts more aggressively than a standard single-start tap, enabling faster thread formation in through-holes and reducing tapping time without compromising thread quality. Ideal for production environments or DIY projects where efficiency matters.
• Right-hand metric thread: M13x1.75 is the standard metric size for many components and assemblies. This tap produces reliable, conventional right-hand threads that pair seamlessly with common fasteners and nuts used in machinery, automotive, and fabrication work.
• ISO 529 compliant geometry: The tap geometry adheres to ISO 529 dimensions, ensuring consistent fit and compatibility with other ISO-threaded parts. Expect smooth tapping action and repeatable thread profiles across multiple projects.
• Uncoated HSS for versatility: Uncoated high-speed steel provides robust performance across a broad range of materials, from steel and cast iron to aluminum and certain non-ferrous alloys. The absence of coating reduces friction buildup in tight tolerances and helps you tailor lubrication to the job at hand.
• Ground thread and precise construction: The ground thread profile delivers crisp minima and consistent pitch, resulting in clean internal threads that hold fasteners securely. This is especially valuable when accuracy matters for fitment and long-term reliability.
• General-purpose utility: Designed as a reliable all-around tap, it’s well-suited for repair work, prototyping, and production machining alike. Whether you’re threading a small batch of parts or outfitting a tool crib, this tap covers a wide range of common applications.

This tap shines in scenarios like repairing stripped threads in aluminum housings, threading through-holes in steel frames, or creating new internal threads in fabrications where quick cycle times are beneficial. It’s a practical choice for machine shops, fabrication shops, and meticulous hobbyists who value a durable, repeatable tapping solution without needing specialized tooling for every job.

How to get the best results

• Use a suitable pilot hole sized for M13x1.75 per ISO guidelines to ensure proper engagement and minimize breakage.
• Apply a quality tapping lubricant or cutting oil to reduce heat, improve chip evacuation, and extend tap life.
• Maintain steady, even pressure and avoid forcing the tap; back out occasionally to clear chips for consistent threads.
• Work within your material’s limits—stiffer metals may benefit from slower feed rates and prudent lubrication to preserve edge integrity.

Why choose Wiseman threading tools — Wiseman brings decades of precision tooling experience to your workshop. The combination of a robust HSS core, a second-lead geometry for speed, ISO 529-compliant dimensions, and uncoated versatility translates to dependable performance across many projects. It’s the kind of tooling decision you’ll notice in the quality of your threads, the consistency of your results, and the speed with which you complete jobs.

Compatibility and care: This is a right-hand thread tap intended for standard metric threads. After use, clean away chips, wipe the tap dry, and store in a dry environment to prevent corrosion. Regular lubrication during use will maximize tap life and maintain thread fidelity across many applications.
