Wiseman Left-Hand M24x1.5 Second-Lead HSS Tap

Precision-ground high-speed steel threading tool designed for internal threads in metal, with a left-hand orientation and a second-lead design that speeds up cutting. This uncoated tap follows ISO 529 dimensions for dependable compatibility with standard tooling and drill setups. The entry is optimized for North American workpieces with a USA plug lead configuration, delivering reliable starts and consistent results.

• Material and finish: High-speed steel (HSS), ground for sharp, accurate threads; uncoated to handle typical shop temperatures and reduce coating buildup.
• Thread specification: Left-hand thread, M24 x 1.5 pitch; second-lead design accelerates thread formation and improves chip control.
• Standards and compatibility: ISO 529 dimensional profile ensures predictable performance with standard taps, guides, and drill sizes.
• Lead configuration: USA plug lead for straightforward alignment and smooth engagement in common North American applications.
• Ideal applications: Tap internal threads in soft to medium alloys and steels where a reverse-threaded fastener is required or where easy disassembly is anticipated.

How to use for best results: begin with a correctly sized pilot hole, apply a light coating of cutting fluid or oil, and maintain steady, even pressure as you cut. For left-hand threads, rotate opposite to standard right-hand taps. The second-lead feature helps chips evacuate more efficiently, reducing heat buildup and yielding cleaner threads in fewer passes.

Why this Wiseman tap stands out: a robust HSS composition paired with precise grinding and a dedicated left-hand, second-lead design offers faster, more reliable tapping without sacrificing thread accuracy. It’s an ideal addition for machine shops, repair technicians, and serious DIYers who need dependable M24x1.5 left-hand threads with efficient cutting performance.

Care and longevity: keep the tap clean and dry when not in use, store it in a protective sheath, and use appropriate lubrication during tapping to extend tool life and maintain thread quality.
