Wiseman Threading Tools Second Lead Metric HSS Tap Right Hand - M16x2

Introducing the Wiseman Threading Tools Second Lead Metric HSS Tap Right Hand - M16x2, a precision threading tap built for dependable, repeatable results in metalworking projects. This uncoated, high-speed steel tap is ground to tight tolerances and follows ISO 529 dimensions, ensuring compatibility with standard metric nuts and threaded holes.

Why this tap stands out

• Second lead design (two-start thread): The dual-start geometry reduces the number of turns required to cut the thread, delivering faster, smoother tapping and improved grip on tough materials.
• High-speed steel, ground finish: A precisely ground HSS flute profile provides clean, accurate threads and extended tool life, even when cutting through moderately hard metals.
• Right-hand, metric M16x2: Optimized for standard right-hand threads, this tap creates a reliable 16 mm diameter thread with a 2 mm pitch, suitable for a wide range of mechanical assemblies.
• Uncoated versatility: The bare steel surface accepts a variety of cutting fluids, allowing you to tailor lubrication for each material and finish you work with.
• ISO 529 compliant: Designed to meet established dimensional standards, so you can trust consistent thread profiles across jobs and with standard fasteners.

What this tap is designed to do

Whether you’re building machinery, fabricating brackets, or repairing equipment, this Wiseman tap excels at creating clean, strong internal threads in through-holes. The M16x2 size is a common choice for mid-range fasteners, making it a practical addition to any workshop, machine shop, or DIY setup. The right-hand threading ensures intuitive operation—clockwise rotation to cut, counterclockwise to reverse or back out with ease.

Ideal use cases

• Tapping through-holes in steel, cast iron, aluminum, brass, and other common metals for robust fasteners.
• Prototyping and repair work where reliable internal threads are critical for assemblies and fixtures.
• General maintenance tasks in automotive, industrial, and fabrication settings where metric M16x2 threads are required.

Practical guidance for best results

• Always use an appropriate cutting fluid or oil to reduce heat and extend tool life. Repeated lubrication during the tapping process improves chip evacuation and thread quality.
• Align the tap square to the hole and start with a light, steady motion. Maintain steady pressure to prevent off-axis cuts that can ruin thread accuracy.
• Back off periodically to break chips and prevent binding. Clean the hole and reapply lubricant to maintain a consistent cutting action.
• Pair with the correct matching metric nut or threaded hole and ensure the pilot drill size is suitable for M16x2 to achieve optimal engagement and thread integrity.

Who benefits most

• Professional machinists and shop technicians needing dependable, repeatable metric taps for mid-sized threads.
• Hobbyists and makers who value real-world performance, precision threading, and a durable tool that stands up to regular use.
• Maintenance teams performing on-site repairs where quickly established, accurate threads are essential for downtime reduction.
