Wiseman Spiral Point Metric HSS Tap – Right Hand, M16x1.5

Tackle metric threading with precision using the Wiseman Threading Tools Spiral Point Tap. Ground high-speed steel (HSS) and thoughtfully engineered for general purpose use, this tap is designed to deliver clean, accurate M16x1.5 threads in a variety of common metals. Its ISO 529 dimensions ensure compatibility with standard drill sizes and machined holes, making it a reliable choice for shop benches and professional tooling kits alike. The spiral point (gun nose) geometry guides chips forward as you advance, helping you maintain alignment and reduce tap breakage when threading through holes. Right-hand threading keeps the operation intuitive for most workshops and everyday projects.

Whether you’re repairing a chassis, fabricating a new component, or performing maintenance on equipment, this tap gives you predictable performance without the fuss of specialty tooling. The uncoated, plain-HSS construction prioritizes durability and straightforward use in typical factory and home-shop environments, offering a robust option for through-hole tapping where efficient chip evacuation matters most.

Why this Wiseman tap stands out

• Spiral Point (Gun Nose) design that pushes chips ahead of the cutting edge, enabling smoother entry and faster material removal in through-holes. This geometry is a well-established choice for efficient tapping and reduced drag, especially when you’re threading in one pass.
• Metric M16x1.5, right-hand thread—a popular size for structural hardware and mechanical assemblies, aligning with standard practice so you can source mating parts and fasteners with confidence.
• ISO 529 dimensions ensures predictable fit in standard drilled holes and aligns with global threading conventions, simplifying workflow across machines and hand-tapping tasks.
• High-speed steel (HSS) ground finish provides dependable rigidity and edge retention for general-purpose threading in common metals, making it a versatile addition to any tap collection.

Ideal use cases and who benefits most

This tap excels in standard metalworking tasks where clean, reliable M16x1.5 threads are required in through-holes. It’s a solid fit for:

• Machinists and workshop technicians performing on mild steel, cast iron, and aluminum components.
• Maintenance and repair work on equipment that uses metric fasteners with a 16 mm major diameter.
• Fabrication projects where fast cycle times matter and chip evacuation through holes is essential.

In practice, you’ll reach for this tap when you need a straightforward, dependable tool that consistently yields true threads without the complexities of specialty coatings or exotic geometries. The spiral point helps keep the tap on course, even as you work through standard through-holes, while the right-hand thread matches the majority of commercial fasteners and assemblies.

Practical guidance for best results

• Prepare the hole with a drill size appropriate for ISO 529 M16x1.5 threads, then use the Wiseman tap to establish the thread in a single pass with steady, clockwise rotation.
• Use a suitable tapping lubricant or cutting fluid to reduce friction and extend tool life; maintain gentle, continuous pressure and avoid forcing the tap.
• Periodically reverse slightly to break chips during hand tapping, especially in harder materials or longer thread depths.
• Ensure workholding is secure to minimize deflection; keep the tap perpendicular to the work surface for a true, concentric thread.
