The Wiseman Threading Tools Bottom Lead Metric HSS Tap Right Hand - M40x3 is a precision, general‑purpose internal threading tool designed for dependable metric threads in a variety of metals. Ground from high‑speed steel and offered uncoated, it delivers a clean, repeatable cut with tight tolerances that align with ISO 529 specifications.

• Thread direction and size: right‑hand tap for M40x3 internal threads, enabling accurate creation of female threads in drillable holes.
• Material and finish: high‑speed steel (HSS) ground for precise geometry and durable cutting performance, uncoated for efficient heat dissipation during tapping.
• Lead form: bottom lead configuration to promote progressive engagement and reliable cutting through the workpiece.
• Standards and compatibility: ISO 529 compliant, ensuring consistent fit with standard hole sizes and common machining setups.
• Ideal applications: a solid choice for workshop threading tasks in metalwork—from maintenance repairs to new fabrications—where a robust metric tap is needed.
• Practical use tips: apply light cutting fluid or oil, maintain steady, perpendicular alignment, and back off periodically to clear chips for smooth, accurate threading and extended tap life.

With its robust HSS composition, precise ground form, and dedicated bottom lead design, this M40x3 right‑hand tap is built to deliver reliable, repeatable threads in a workday’s worth of production or repair projects.
