Wiseman Threading Tools Spiral Point Metric HSS Tap Right Hand - M16x1

Engineered for serious metalworking, the Wiseman Threading Tools Spiral Point Metric HSS Tap Right Hand – M16x1 is a precision internal threading tool designed to deliver fast, reliable taps in through-holes. Crafted from high-speed steel and ground to tight tolerances, this uncoated, general‑purpose tap follows ISO 529 dimensions to ensure consistent thread quality across jobs.

• Spiral point (gun nose) geometry: Directs chips ahead of the cutting edge, minimizing orbiting chips and reducing the risk of clogging in through-holes. This makes the tap ideal for quick, clean internal threads in shorter production runs or maintenance tasks.
• Right-hand thread, metric M16x1: Suited for standard fasteners and applications that rely on conventional clockwise threading. The precise pitch and diameter conform to ISO 529, giving you dependable results time after time.
• High-speed steel, ground finish, uncoated: The rigid HSS core and smooth ground surface provide consistent thread form and durability under normal tapping speeds. The lack of coating keeps lubrication options flexible, helping you tailor cutting fluid to the material at hand.
• General-purpose capability: Ideal for through-holes in common metals encountered in maintenance, fabrication, and light production environments. Whether you’re repairing aged components or setting up new assemblies, this tap delivers stable performance with minimal chatter when used with proper lubrication.

Use scenarios and practical tips to get the most from this tap:

• When tapping through-holes in steel, cast iron, or aluminum, start with a sharp drill size per ISO 529 recommendations to ensure a clean, accurate pilot hole before tapping.
• Use a quality tapping fluid or cutting oil to reduce friction, extend tool life, and improve chip evacuation. Apply lubricant to the tap flute and the workpiece surface before starting.
• Maintain a steady, clockwise rotation with gentle, consistent pressure. Avoid hard impacts or side load that can chip the teeth or misalign the thread.
• Periodically back off slightly during tapping to break and clear formed chips, then resume to maintain smooth progress and prevent chip buildup.
• After tapping, deburr the hole and inspect the thread for uniform engagement and a clean thread profile that mates cleanly with a fastening screw or bolt.

The Wiseman Spiral Point Metric HSS Tap is an essential addition to any machinist’s or maintenance technician’s toolkit. It brings reliable, repeatable internal threading to through-holes, supporting precise fastener fitment and robust assemblies in everyday applications. For consistent results, pair this tap with proper lubrication and the correct ISO 529 tapping drill size, and you’ll experience clean threads and dependable performance job after job.
