Wiseman Threading Tools Fluteless Metric HSS Tap - M2x0.4

Wiseman Threading Tools Fluteless Metric HSS Tap – M2x0.4 is a precision-made internal-threading tool designed for small-diameter workpieces. Crafted from high-speed steel and ground to exact tolerances, this tap is uncoated for reliable performance across a range of ductile materials. Its flute-less, thread-rolling design forms threads rather than cutting them, delivering a stronger, smoother fit that improves assembly longevity.

Why the fluteless (thread-rolling) approach matters

• Forms threads by plastic deformation, yielding higher fatigue strength and a clean interior finish—ideal for precision fits in miniature components.
• Produces minimal burrs and eliminates chip formation typical of traditional cutting taps, reducing the risk of jam or binding in tight holes.
• Flute-less design plus uncoated surface helps maintain consistent performance with simple, dependable lubrication.

Specifications at a glance

• Thread size: M2x0.4 (metric fine pitch)
• Material: High-speed steel (HSS)
• Finish: Uncoated
• Standards: ISO 529 dimensions
• Thread direction: Right-hand
• Design: Fluteless (thread-rolling)

Ideal applications

• Small electronic enclosures, precision housings, and miniature mechanical assemblies
• Aluminum, brass, and mild steel components where strong, accurate internal threads are essential
• Prototype builds, hobbyist projects, repairs, and miniature fabrication tasks

How to get the best results

• Use the appropriate pre-drilled hole size per ISO 529 for M2x0.4 and maintain perpendicular alignment with the workpiece.
• Lubricate sparingly with a light cutting oil or tapping fluid to optimize thread formation and reduce friction.
• Operate with steady, even pressure in a tapping sequence; avoid forcing the tap to prevent deflection and ensure a clean thread.
• Clean the hole and tool after use to preserve the form and prevent galling on future projects.
