Introducing the Wiseman Threading Tools Second Lead Metric HSS Tap, Right Hand - M25x1. This precision ground, high-speed steel tap is engineered for fast, reliable internal threading in metal parts, with an uncoated finish that delivers efficient cutting and easy lubrication. Built to ISO 529 dimensions, it guarantees compatibility with standard metric holes and thread profiles found in professional shops and home workshops alike.

• Second lead design: a dedicated second-lead geometry guides the cutting action after the initial taper, promoting quicker alignment and producing cleaner, more consistent threads with reduced chatter.
• Right-hand, metric thread: M25x1, standard right‑hand threading for a broad range of applications—from repair work to new components.
• USA plug lead: optimized lead configuration for stable entry and reliable starting performance in manual tapping setups.
• ISO 529 compliant: precision diameter and pitch specification that aligns with industry standards for interchangeability and quality control.
• Uncoated HSS: high‑speed steel ground for durability and efficient cutting, with an uncoated surface that can enhance lubrication retention in typical workshop conditions.
• Versatile, professional-grade tooling: a trusted choice for fabricators, machinists, and serious hobbyists who demand repeatable results when creating or repairing internal threads in steel, cast iron, and alloys.

Usage considerations and best practices: apply a quality cutting fluid or tapping lubricant for smoother cuts and longer tool life. Maintain proper alignment as you begin threading to avoid cross-threading, and periodically back the tap out to break chips and prevent binding. Pair this tap with a compatible tap wrench for controlled, steady turning, and choose the appropriate pilot hole size per ISO 529 guidance to achieve clean, true threads every time.
