Wiseman M27x1 Second Lead HSS Tap — Right Hand Thread, General-Purpose, Uncoated

The Wiseman Threading Tools M27x1 second lead metric tap is built for dependable, everyday threading in metalworking projects. Crafted from high-speed steel and ground to precise tolerances, this uncoated tap delivers consistent cutting action and clean, accurate threads. With ISO 529 dimensions and a right-hand, double-start (second lead) design, it speeds up your threading process while maintaining thread integrity.

• Material and finish: High-speed steel (HSS), ground to ISO 529 specifications, uncoated for predictable cutting performance and compatibility with standard threading fluids.
• Thread geometry: Metric M27x1 with a second lead (two starts) and a right-hand thread, enabling faster engagement and deeper thread formation with fewer turns.
• Lead type: USA plug lead, designed for efficient, smooth entry and reliable thread progression in typical shop environments.
• Applications: Ideal for general-purpose threading in steel, cast iron, aluminum, and other common metals found in fabrication, maintenance, and repair work.
• Compatibility: ISO 529 compliant dimensions ensure proper fit with standard tap drills and mating fasteners within the metric system.
• How to use: Begin with a properly sized pilot hole per ISO 529 guidelines for M27x1, apply a high-quality cutting fluid, and use steady, controlled torque. Back off occasionally to clear chips and prevent binding, then continue until the full thread length is formed.
• Care and longevity: After use, wipe clean and apply a light protective oil, store in a dry environment, and keep the tool free from moisture to extend life.

Choose the Wiseman Threading Tools M27x1 second lead HSS tap when you need reliable, efficient threading performance in a range of metalworking tasks—from quick repair work to precision fabrication. The double-start design reduces turning effort while delivering strong, consistent threads, making it a practical addition to any machinist’s toolkit.
