Wiseman Metric Fine HSS Hand Tap Set — ISO 529, M39x1.5

Achieve precisely cut internal threads with confidence using this Wiseman Hand Tap Set. Crafted from high-speed steel and ground for sharp, clean edges, these taps deliver dependable performance across a range of metalworking tasks. The uncoated finish ensures consistent engagement and predictable wear, making the set a reliable workhorse in professional shops and serious DIY projects alike.

Key features and why they matter

• High-speed steel ground taps provide durable cutting edges and lasting sharpness for multiple uses, reducing the need for frequent replacements.
• Uncoated design offers straightforward cutting action and easier chip clearance, delivering steady performance without coatings that can mask wear or affect fit.
• ISO 529 dimensions guarantee compatibility with standard metric threads, so you can trust that M39x1.5 taps will thread cleanly with mated components.
• Right-hand thread orientation matches the most common threading requirements in metalworking projects, making this set a versatile choice for everyday tasks.
• Three leads: taper, second (plug), and bottoming provide a complete progression—from a gentle start to deep, full-depth threads—minimizing run-out and improving accuracy.
• Metric fine thread size: M39x1.5 enables precision threading for a variety of mechanical assemblies and repaired components.

What you can accomplish with this Wiseman hand tap set

• Fabricate clean internal threads in metal housings, brackets, and fixtures where metric fasteners are required.
• Repair damaged threads by removing burrs and restoring a true, concentric thread path without oversizing the hole.
• Support prototyping and iterative design work by quickly creating accurate threaded holes for testing and assembly.

Who benefits most

This set is ideal for machinists, metalworkers, workshop technicians, and serious hobbyists who need reliable, consistent thread cutting with metric fine threads. Its ISO-standard dimensions and proven HSS performance make it a practical choice for both routine maintenance tasks and complex fabrication projects.

Practical considerations

• Use with a suitable hand tap wrench or die plate to maintain square alignment and prevent cross-threading.
• Operate with steady, even pressure and an appropriate thread-cutting lubricant to optimize cutting action and extend tool life.

Invest in the Wiseman Metric Fine HSS Hand Tap Set to simplify your threading work, deliver accurate M39x1.5 threads, and stand up to repeated use in demanding metalworking environments.
