The Wiseman Threading Tools Second Lead Metric HSS Tap, Right Hand - M27x2 is a purpose-built threading solution designed for serious metalworking projects. This uncoated, general‑purpose tap is ground from high-speed steel (HSS) to deliver dependable cutting action and long, repeatable results in a busy workshop.

Why this tap stands out

Designed around ISO 529 dimensions, this tap guarantees compatibility with standard M27x2 through-holes and threaded cavities. The right-hand thread is optimized for typical production work, while the second lead geometry advances the start of cutting and improves chip evacuation. The combination reduces the likelihood of tap deflection and chatter, helping you achieve cleaner threads faster and with less effort.

Key benefits at a glance

• Second lead design accelerates cutting and enhances chip flow for quicker, smoother threads.
• Uncoated HSS provides predictable performance, easy resharpening, and robust durability in standard shop conditions.
• ISO 529 compliant ensures accurate thread form and compatibility with common M27x2 components.
• Right-hand thread ideal for most general-purpose applications in steel, cast iron, aluminum, and brass.
• USA plug lead contributes to reliable starts and consistent engagements in typical domestic machining setups.

Practical applications and best practices

Ideal for repairing or fabricating through-holes and threaded inserts in a range of metals. For best results, pair this tap with a properly sized pilot hole according to tapping charts for M27x2, apply appropriate cutting fluid, and maintain steady, even torque. Let the tap do the work—avoid forcing it, back off periodically to break chips, and keep the workpiece well-supported to prevent deflection.

Who should use it

Machinists, metal fabricators, hobbyists, and maintenance technicians who need reliable, single‑tool performance for medium to large diameter threads. If your work routinely calls for M27x2 right‑hand threads, this Wiseman tap provides a consistent, predictable threading experience from first cut to final thread.
