Wiseman Threading Tools Taper Lead Metric HSS Tap Right Hand - M18x2.5

Wiseman Threading Tools – Taper Lead Metric HSS Tap (Right Hand) – M18x2.5 is a purpose-built, high-precision thread tap designed for reliable internal threading in a wide range of metals. Ground from high-speed steel and uncoated, this tap adheres to ISO 529 dimensions and features a taper lead that makes starting threads smooth and predictable, even in challenging holes.

• Size and thread: M18x2.5 with a right-hand thread, ideal for standard clockwise threading in metal parts.
• Taper lead: A gradual lead-in at the start of the thread reduces cross-threading and eases alignment, delivering cleaner cuts and less user effort during the initial turns.
• Material and finish: High-speed steel (HSS) with precise grinding for dependable performance across a variety of metals; uncoated to maximize compatibility with cutting oils and coolants.
• Standards: Conforms to ISO 529 dimensions, ensuring predictable fit with standard pre-drilled holes and compatible components.
• Applications: A versatile general-purpose tap suitable for fabrication shops, automotive repairs, hobbyist projects, and classroom labs. Works well for through-holes and moderate-length blind holes when paired with proper lubrication.

This taper-lead HSS tap is designed for steady, confident threading sessions. Use with a tap wrench or compatible machine tapholder, apply cutting oil or lubricant, and advance with steady, even pressure. Clear chips frequently to maintain accurate thread formation and prevent binding.

Why choose this Wiseman tap? It combines durable HSS construction with precision-ground geometry, ISO-standard sizing, and a practical taper lead that reduces start-up friction. If you’re building or repairing threaded assemblies in metal, this tap offers consistent performance, reliability, and repeatable results—day in and day out in the shop or on the workbench.

Care and tips:

• Use a suitable cutting oil to extend tool life and improve finish.
• Begin threading with a gentle, coaxing motion to engage the job’s centerline; back off to clear chips as needed.
• After use, clean the tap and store it in a protective case to preserve the precision grinding.
