The Wiseman Threading Tools Metric Fine HSS Hand Tap Set ISO529 - M38x1.5 is a precision-made tapping solution designed for reliable, repeatable thread cutting in metal. Ground and uncoated high-speed steel deliver steady performance across common workshop materials, with ISO 529 dimensions that guarantee compatibility with standard female threads. This set features a right-hand thread and is tailored for metric fine-thread applications, making it a dependable choice for maintenance, repairs, and fabrication projects. What makes this set stand out

• Metric fine threading, M38x1.5: specifically sized for accurate, tight threads in metal components, ensuring a precise fit and strong fastenings.
• ISO 529 compliant: engineered to standard dimensions so you can rely on consistent results with mating parts and standardized hardware.
• Ground, uncoated HSS taps: classic general‑purpose taps that balance durability with easy lubrication and chip control, and that respond well to your preferred cutting fluids.
• Three-lead set for complete threading: includes taper (starting), second/plug (finishing), and bottoming taps to complete the full thread depth in a single hole.
• Right-hand thread: optimized for typical hand‑tapping operations with a tap wrench and gentle, steady pressure.

How to get the best results

1. Drill a pilot hole sized appropriately for M38x1.5 using standard metric thread guidelines.
2. Begin with the taper tap to establish the thread profile and alignment.
3. Advance to the plug/second tap to refine the thread length and accuracy.
4. Finish with the bottoming tap to achieve full thread depth to the bottom of the hole.
5. Use a suitable cutting fluid or lubrication, and keep the workpiece steady to prevent thread distortion.
6. Back off occasionally to break chips and clean the hole as you progress.

Ideal applications and who benefits

• Professional machinists and maintenance technicians performing metric thread repairs or new builds requiring M38x1.5
• Engineers and fabricators working with steel, aluminum, and other common metals needing reliable, reproducible threads
• DIY enthusiasts tackling automotive, machinery housings, or equipment enclosures where metric fine threads are specified

Why choose this Wiseman set - Reliable, universal tool for everyday metalworking tasks with metric threads - ISO 529 compliance minimizes guesswork and ensures compatibility with standard nuts, bolts, and inserts - Uncoated HSS offers straightforward lubrication compatibility and potential re-sharpening when needed - Ground geometry provides consistent cutting edges and better hole finish Care and maintenance for longevity

Wipe clean after use, apply a light stay-dry lubricant, and store in a protective case to prevent corrosion and maintain threading accuracy for years of service.
