Wiseman Threading Tools Spiral Flute Metric HSS Tap Left Hand – M24x3 is a precision, general‑purpose machine tap designed for clean, reliable left‑hand threading in metalwork. Built for durability and consistent results, it’s a versatile choice for engineers, machinists, and repair technicians tackling reverse‑threaded applications.

Key features at a glance

• Material and finish: High‑speed steel (HSS), ground for precise profile and reliable cutting in a variety of metals. Uncoated construction simplifies use with standard cutting fluids and general purpose tapping.
• Thread orientation and size: Left‑hand thread, M24x3. This reverse thread makes it ideal for components that require opposite threading directions or for reverse‑torque applications.
• Flute geometry: Spiral flute design. The helical flutes actively evacuate chips from the hole, reducing clogging and enabling deeper, steadier tapping in blind or through holes. This geometry also provides greater strength and smoother cutting action than some straight‑flute alternatives.
• Standards and fit: ISO 529 dimensions ensure compatibility with standard hole sizes and tap crews, reducing guesswork and improving interchangeability with other tools in the workshop.
• Application versatility: Ideal for general purpose threading in ferrous and non‑ferrous metals, including steel, cast iron, and aluminum, where reliable left‑hand threads are required or where reverse threading is used to secure assemblies.
• Usage note: For best results, drill the correct pilot hole, apply appropriate cutting fluid, and follow proper tapping technique. Left‑hand taps cut when the tool is rotated in the reverse direction (counterclockwise) to form the left‑hand thread.

Why choose this Wiseman tap? The spiral flute geometry, combined with high‑speed steel and precise grinding, translates to faster chip clearance, smoother entry, and reduced risk of tap breakage in demanding applications. Its left‑hand configuration expands your toolkit for mechanical assemblies that rely on reverse threading, making it a dependable choice for repair work, specialized hardware, and manufacturing setups where thread direction matters.

Practical use scenarios

• Installing left‑hand threaded fasteners or components that rotate in the opposite direction to the majority of hardware.
• Repair work where a reverse thread is required to secure a part or to remove a seized fastener through reverse shear.
• Deep or blind holes where efficient chip evacuation keeps cutting forces steady and reduces dwell time at depth.

With its compact, purpose‑built design, this M24x3 spiral flute HSS tap from Wiseman is ready to slot into standard tapping setups, delivering consistent results you can trust across multiple jobs and materials.
