Wiseman Threading Tools Bottom Lead Metric HSS Tap Right Hand - M45x4.5 is a precision ground tapping tool built for reliable metric threading in metalworking projects. Crafted from high-speed steel (HSS) and finished uncoated for general-purpose use, this tap delivers consistent cut quality across a range of common machinable metals.
Designed to ISO 529 specifications, it ensures compatibility with standard hole sizes and production setups. The right-hand thread combined with a bottom lead offers stable engagement from the first turn and smooth cutting action, making it well-suited for through-hole tapping and deep thread formation in demanding applications.
- Material and finish: HSS ground, uncoated for dependable performance across steel, aluminum, brass, and other machinable materials.
- Threading profile: Right-hand thread with bottom lead to promote easy start-up and controlled material removal.
- Size and standard: Metric M45 × 4.5, aligned with ISO 529 for predictable, repeatable results.
- Application scope: General-purpose tapping in a variety of metals; ideal for through-hole work and situations requiring a robust, large-diameter thread.
- Usage tips: Pair with appropriate cutting fluid or oil, maintain perpendicular alignment to the workpiece, and back off slightly to clear chips on deeper cuts for a cleaner finish.
This tap is an excellent choice for machinists, maintenance technicians, engineers, and serious hobbyists who regularly tackle metric threads at larger diameters. With Wiseman’s proven threading tools, you gain durable tooling that promotes accurate thread profiles, reduces rework, and delivers consistent performance across repeated use in production or fabrication settings.
