Wiseman Threading Tools Second Lead Metric HSS Tap Right Hand - M18x2 is a high-speed steel ground thread tap designed for dependable general‑purpose threading in common metals. Built to ISO 529 dimensions with a right‑hand thread, this tap delivers consistent, clean cuts in through‑holes and blind holes alike. The second lead (two‑start) design accelerates the tapping process, helping you finish projects faster without sacrificing thread accuracy. (USA Plug lead)

Key features at a glance:

• Second lead for speed: Two cutting starts along the shank increase material removal per turn, reducing cycle time on production work while preserving thread integrity. This approach is common in metric HSS taps that aim to boost throughput without compromising fit.
• Uncoated HSS, general purpose: High‑speed steel provides good toughness and versatility for a wide range of steels and non‑ferrous alloys; the uncoated finish keeps the tool affordable and easy to sharpen or rework in workshop environments. (Product description reference)
• ISO 529 standards: The tap adheres to metric ISO 529 specifications for accurate thread form and compatibility with standard tooling and fasteners.
• Right‑hand thread: The conventional threading direction for most manual and machine tapping applications, ensuring predictable results when faced with standard fasteners and assemblies.

Who benefits most

• Machinists and hobbyists working with through‑holes in steel, cast iron, aluminum, and other common metals who want faster threading without sacrificing accuracy.
• Production environments where tapping speed matters and consistent thread quality is essential for reliable fastener engagement.

Practical tips for best results

• Use appropriate cutting fluid or lubrication to reduce friction and extend tap life, especially when tapping harder materials. Maintain a steady, straight approach to keep threads true and burr‑free.
• Align the tap carefully with the hole and avoid over‑tapping; clear chips frequently to prevent thread packing and tool fatigue.
• Match the drill size to the standard tapping chart for M18x2 and the second‑lead geometry; if in doubt, consult a reliable tapping reference to ensure optimal material removal and thread depth.
