Designed for durability and precision, the Wiseman Threading Tools Second Lead Metric HSS Tap in M48x3 is an uncoated high-speed steel tap built for general-purpose through-tapping in a wide range of metals. Its ISO 529-compliant geometry and right-hand thread deliver consistent, dependable threads with every cut.

• Material and finish: High-speed steel ground for reliable performance across common metals. Uncoated taps excel in versatility, offering strong cutting action and straightforward tool maintenance.
• Thread specification: Right-hand thread with a second lead (USA plug lead). The second lead accelerates tapping without sacrificing thread quality on suitable materials, helping you complete jobs faster.
• Size and fit: M48x3 metric size, designed for standard through-hole tapping. Follow ISO 529 guidelines for hole diameter and drill size to achieve the correct thread engagement.
• Lead configuration: Second lead tap with USA plug lead characteristics, optimized for efficient chip evacuation and smoother cutting in typical workshop environments.
• Versatility: Everyday-use tool ideal for machine shops, maintenance bays, automotive work, and DIY metal projects where dependable, fast-threading is essential.
• Durability in use: Precision-ground geometry supports clean start, reduced runout, and consistent thread profile even after multiple passes in non-hardened metals like aluminum, brass, steel, and cast iron.

Practical usage tips to extract maximum value:

• Always apply a suitable cutting fluid or tapping oil to minimize heat buildup and extend tap life.
• Keep the tap square to the hole and back out periodically to clear chips, maintaining smooth cutting action.
• Secure the workpiece in a stable fixture or drill press chuck to preserve perpendicular alignment and prevent thread wander.

Why this Wiseman HSS tap stands out: the combination of ISO 529-compliant geometry, second-lead threading, and a robust HSS core translates to faster cycle times, reliable thread formation, and fewer reworks—whether you’re producing prototype parts or performing routine maintenance.
