Experience precise, efficient threading with the Wiseman Threading Tools Second Lead Metric HSS Tap Right Hand - M38x1.5. This uncoated, ground high-speed steel tap is built for general-purpose use, delivering clean, consistent threads in a wide range of metals while standing up to repeated production runs.

Why this second-lead HSS tap stands out

• Second lead design (two-start) for faster cutting: fewer turns to reach full depth, increased throughput in busy shops without sacrificing thread integrity.
• High-speed steel (HSS), ground finish ensures durable performance, precise tooth geometry, and reliable chip removal for smooth cutting action.
• Uncoated for versatility compatibility with a variety of lubricants and workpiece materials, making it a reliable choice across projects from prototype to production.
• Right-hand thread aligns with standard machining practices, simplifying setup and reducing the chance of cross-threading in typical assemblies.
• ISO 529 compliant dimensions guarantee compatibility with standard M38x1.5 holes and mating components, enabling straightforward replacement and interchangeability.

What you can achieve with this tap

Whether you’re repairing a worn thread, fabricating a new component, or performing routine maintenance, this tap delivers dependable results. The M38x1.5 size is common in heavy-duty applications, making this tool a reliable choice for:

• Automotive and motor-sport components requiring robust metric threads
• Gear housings, housings, and metal enclosures that demand strong, precise threads
• Industrial machinery and hydraulic fittings where consistent engagement is essential
• Prototype builds and small-batch production where speed and accuracy matter

Practical usage and care

• Use the recommended tapping drill size per ISO 529 for M38x1.5 to ensure proper thread formation and chamfer setup.
• Apply light, consistent lubrication to reduce friction, extend tool life, and improve chip evacuation.
• Align the tap carefully with the hole to prevent thread deformation and avoid cross-threading.
• Back off slightly after each full thread to break and clear chips, then continue cutting with steady, even pressure.
• Clean the tap after use and store in a dry environment to prevent corrosion and maintain edge geometry.

Who benefits most

Ideal for professional machinists, shop technicians, metrology and maintenance teams, and serious hobbyists who demand dependable performance from a metric, right-hand, two-start thread tap. It’s a practical, no-nonsense choice when speed, consistency, and ISO-standard accuracy matter most.
