Wiseman Threading Tools Second Lead Metric HSS Tap Right Hand - M36x3

The Wiseman Second Lead Metric HSS Tap in M36x3 is a precision-made plug tap designed to finish internal threads with reliable accuracy. Forged from uncoated High-Speed Steel and ground to ISO 529 dimensions, this right-hand, second-lead tap delivers consistent thread formation across a variety of general-purpose applications. Designed for durability and everyday threading tasks, it’s a dependable tool for hand tapping and small-scale production work.

Why this Wiseman tap stands out

• Second-lead (plug) design: Provides a balanced lead that starts smoothly and finishes cleanly, ideal for completing threads after initial cutting. This mid-range lead is a staple in US practice and is widely recognized as the finish-pass tap in many threading workflows.
• M36x3, right-hand, ISO 529: Precise metric sizing with a standard right-hand thread, ensuring compatibility with standard metric nuts and components. ISO 529 compliance means predictable results across compatible workpieces.
• High-Speed Steel, uncoated: A robust, general-purpose material that holds sharp cutting edges for numerous threading tasks without coatings that can wear off in busy shop environments.
• Single-tool versatility: Suited for through holes and blind holes where a finishing pass is required, helping to achieve full thread depth without over-cutting.
• Practical, widely applicable geometry: Ground thread form supports clean chip formation and steady progression along the bore, reducing the risk of cross-threading and chatter in common metals like steel and aluminum.

Ideal use cases

This tap is perfect for workshops and job sites where metric threading is routine—engineered parts, automotive assemblies, and fabrications that require reliable internal threads at M36x3. It’s especially effective as a finishing step after an initial lead was cut, or when precision is needed in blind or through holes. For regions where plug/second taps are the standard finish-pass tooling, this Wiseman tap delivers predictable results with minimal fuss.

Practical guidance for best results

1. Choose the correct drill size for M36x3 per ISO 529 data to ensure proper thread depth and strength.
2. Start with a light lubricating cut, steady hand pressure, and patient advancement to maintain straightness and chip control. Use regular tapping practice for best outcomes.
3. Use this second-lead tap after an initial taper pass or when finishing threads in a hole that’s already been started, to achieve clean, full-depth threads. For complete threading sequences, a taper lead tap and a bottoming (plug) tap are commonly used in combination.

What you gain with the Wiseman tap

Reliability, consistency, and ease of use in metric threading tasks. The M36x3 right-hand, second-lead tap is a practical addition to any machinist’s toolkit, delivering predictable thread geometry that supports snug fastener fits and robust assembly integrity. Its uncoated HSS construction balances performance and value, making it suitable for a broad range of everyday metalworking projects.
