Wiseman Threading Tools Taper Lead Metric HSS Tap Right Hand - M1.4x0.3

Wiseman Threading Tools Taper Lead Metric HSS Tap Right Hand - M1.4x0.3 is a precision-ground high-speed steel thread tap built for consistent, reliable threading in small-diameter workpieces. Uncoated and ISO 529 compliant, this tap delivers predictable results across a range of materials while maintaining exact thread form from the very first cut.

Key specifications

• Thread and lead: taper lead with a right-hand metric thread, M1.4 x 0.3 (major diameter ~1.4 mm, pitch 0.3 mm).
• Material and finish: high-speed steel (HSS) ground for clean flutes and precise thread formation; uncoated to maximize compatibility with cutting fluids.
• Standards: designed to ISO 529 dimensions, ensuring reliable interchange with standard taps and accessories.
• Applications: ideal for general-purpose tapping in soft to mid-strength materials such as aluminum, brass, mild steel, and select plastics.
• Lead configuration: taper lead eases alignment, reduces chatter, and helps start the thread straight on small-diameter holes.
• Orientation: right-hand thread, suitable for the majority of standard assemblies.

What makes this Wiseman tap stand out

The taper lead design combined with precision-ground flutes provides a controlled cutting action, yielding clean, accurate threads with minimal runout. The uncoated HSS surface accepts a wide range of lubricants, giving you flexibility across different materials and cutting fluids. With ISO 529 compatibility, you can pair this tap confidently with standard hole drilling and tapping workflows in both manual and machine-assisted setups.

Practical use cases

• Fabricating small-threaded enclosures for electronics, sensor housings, or micro-mechanical assemblies where compact, reliable fasteners are essential.
• Repair or modifications on thin-walled components where precise M1.4 x 0.3 threads are needed.
• Hobbyist and professional workshops performing bench drilling, drill press operations, or CNC tap routines requiring consistent thread quality.

Tips for best results

• Start with the correct drill size per ISO 529 for M1.4 x 0.3, then deburr the hole before tapping.
• Apply a suitable cutting fluid or light oil to reduce friction and extend tap life; avoid dry tapping on harder materials.
• Turn the tap gradually, keeping it perpendicular to the workpiece; back off periodically to clear chips and prevent binding.
• Use a tap wrench or compatible machine tap setup to maintain straight alignment and prevent thread distortion.

Whether you’re a seasoned machinist or a dedicated hobbyist, the Wiseman M1.4x0.3 HSS tap delivers dependable, repeatable performance for small-diameter threads, making it a fundamental tool in precision threading and detailed fabrication projects.
