Wiseman Threading Tools Taper Lead Machine Nut Metric HSS Tap - M16x2

The Wiseman Threading Tools M16x2 Taper Lead Machine Tap is a purpose-built solution for clean, reliable metric threading in metalwork. Crafted from high-speed steel and ground for a sharp cutting edge, this uncoated tap delivers dependable performance across a range of common metals in practical workshop conditions. The taper lead design and right-hand thread work together to ease entry and control cutting action, helping to start threads smoothly and reduce the risk of cross-threading during the initial engagement. Built to BS 949 general dimensions, it integrates with standard tapping setups and other HSS taps you already rely on in your shop.

Key features that matter in real-world tapping

• Material and finish: High-speed steel (HSS), ground for a precise, sharp cutting edge, uncoated for versatile use with cutting fluids on metal surfaces.
• Lead and threading: Taper lead with a right-hand metric thread of size M16x2, designed to ease alignment and start the cut in through-holes.
• Standards: BS 949 general dimensions ensure compatibility with conventional metric tapping practices and equipment.
• Design purpose: A machine tap intended for metalworking applications where a dependable taper lead thread is preferred to guide the cut and establish accurate threads quickly.

Ideal applications and scenarios

• Fabrication and maintenance work requiring M16x2 threads in steel, cast iron, or similar metals.
• Starting threads in larger through-holes where a gentle lead-in reduces tool chatter and cross-threading risk.
• General purpose threading in workshop settings, usable with tapping machines or traditional tap wrenches paired with cutting fluid.
• Repairs or retrofits where standard metric threads are needed to match bolts, fasteners, or threaded inserts.

Practical usage tips

1. Prepare the hole with a suitable pilot size for M16x2 threads, then secure the workpiece to prevent movement during tapping.
2. Apply a compatible cutting fluid or light oil to reduce friction and extend tap life.
3. Start the tap with steady, light pressure to engage the taper lead, then maintain a constant feed direction and avoid rushing the cut.
4. Periodically back off and clean out chips to prevent binding; continue until the full thread length is formed, then carefully withdraw the tap.
5. Test the new thread with a correctly sized bolt to confirm fit and torque characteristics before final assembly.

With the Wiseman M16x2 taper lead machine tap, you gain a robust, reliable tool that aligns with standard metric threading practices while offering the practical benefits of a taper lead start. This combination helps machinists and fabricators achieve accurate threads with predictable results, improving throughput and reducing rework in everyday threading tasks.
