Precision threading starts with a tool you can trust. The Wiseman Threading Tools M33x1.5 taper lead HSS tap is built for reliable internal threads in metal, following ISO 529 dimensions for consistent results. Its right-hand thread aligns with standard fastening practice, ensuring predictable cuts every time.

The taper lead design is more than a feature—it changes how smoothly threads begin. By distributing cutting forces over a broader area and easing the entry into the material, it reduces startup torque, minimizes chatter, and helps prevent thread tearing, especially on tougher metals or when working with older workpieces. This thoughtful lead geometry is what makes first-thread engagement easier and more forgiving in real-world tapping tasks.

• Material and finish: High-speed steel (HSS), ground for precision and uncoated to maximize compatibility with common lubricants and a wide range of metals.
• Thread type and size: Right-hand metric thread, M33 x 1.5, suitable for standard fastening and assembly applications.
• Lead type: Taper lead, designed to ease thread starting, extend tool life, and provide a smoother cutting action in through-holes and blind holes.
• Standards and compatibility: ISO 529 dimensions ensure accurate pitch and fit with other ISO taps, supporting reliable, repeatable results across projects.
• Usage: Ideal for hand tapping and light machine tapping in general-purpose threading tasks, offering solid performance where precise internal threads are required.

Designed for workshop reliability, this Wiseman tap delivers clean, accurate threads with consistent pitch, making it a dependable choice for maintenance, fabrication, and repair work. Keep it in your toolkit alongside other Wiseman threading tools to tackle a wide range of metric-thread projects with confidence.
