Wiseman Threading Tools Spiral Point Metric HSS Tap Right Hand - M18x1.5 is a rugged, precision-ground tap designed for efficient through-hole threading. Built from high-speed steel and uncoated for general purpose use, this tap adheres to ISO 529 dimensions to ensure reliable compatibility with standard drill and hole sizes.

Key design features that boost productivity

• Spiral Point (Gun Nose): The spiral-point geometry is optimized to push chips forward and out of the hole, reducing clogging and improving thread quality on through-holes.
• Right-Hand Metric Thread: Precisely cut M18 x 1.5 threads in a clockwise direction for standard production and maintenance tasks.
• High-Speed Steel, Ground Finish: A robust, sharp-cutting flute geometry delivers clean threads with dependable longevity in common engineering materials.
• ISO 529 Compliant: Designed to standard specifications, providing predictable thread profiles and easier interchange with compatible tooling and inserts.

What this tap is ideal for

• Through-hole tapping in ferrous and non-ferrous metals where a strong, fast-cutting tool is required.
• Maintenance and production environments where repeatable, consistent thread quality matters for fasteners of M18x1.5 size.
• Applications ranging from automotive brackets to home shop projects where durable HSS tooling delivers reliable performance.

Why choose a spiral point tap for through-holes

• Chips are expelled ahead of the cutting edge, reducing the risk of binding in deeper holes.
• Ideal for through-hole threads where fast cycle times and clean thread starts are critical in repetitive production.

With its combination of ISO-standard dimensions, spiral point geometry, and a durable HSS ground finish, this Wiseman tap is designed to deliver consistent threading results, reduce tool wear, and support a wide range of standard through-hole projects. Whether you’re dialing in a new production process or performing routine maintenance, this M18x1.5 right-hand tap provides predictable performance and solid value in metalworking and fabrication workflows.
