Wiseman Threading Tools Second Lead Machine Nut Metric HSS Tap - M10x1.5 is built for serious metalworking. This high speed steel ground tap delivers consistent, accurate internal threads with a design that prioritizes speed without sacrificing precision.

Two-start design for faster, smoother tapping

• Second lead (two-start) configuration – engineered to improve chip flow and reduce the effort required to initiate threads, making it ideal for thicker workpieces and frequent tapping tasks.
• Designed for general purpose metric threading with reliable performance across a range of machinable metals.
• Right-hand thread, so it aligns with standard fasteners and most common assemblies.

Durable construction meets professional demands

• High-speed steel (HSS) ground finish provides precise thread form and enhanced wear resistance for repeated use in workshop environments.
• Uncoated surface suits a wide variety of cutting fluids and lubricants, offering compatibility with existing tooling setups.
• BS 949 dimensions ensure compatibility with standard tooling inventories and industry expectations for metric taps.
• Specifically sized for M10x1.5 threads, a staple in automotive, machinery, and fabrication applications.

Practical applications and best-use scenarios

• Ideal for producing clean, load-bearing internal threads in mild steel, aluminum, brass, and other common metals.
• Suitable for manufacturing components, repairing housings, brackets, or adapters that require reliable metric threads.
• Perfect for workshops or fabrication shops that rely on repeatable results and longer tool life in general-purpose tapping tasks.

Tips for optimal results

1. Prepare the material and use an appropriate pilot hole size per standard tapping guidelines for M10x1.5 threads.
2. Secure the workpiece and align the tap with a tap wrench or machine tapping setup to maintain a straight, true thread.
3. Apply a suitable cutting fluid or oil to reduce heat and extend tap life; begin slowly and maintain steady, even pressure.
4. Let the second lead cut the thread, and back off occasionally to clear chips and prevent binding.
5. Upon reaching full depth, reverse gently to break chips and remove the tap cleanly.

Care, maintenance, and longevity

• Wipe clean after use and lightly oil to minimize corrosion; store in a protective case to preserve geometry.
• Avoid impact or misalignment to protect the precision thread profile for long-term reliability.

In demanding metalworking tasks, this M10x1.5 HSS tap from Wiseman stands out for its combination of robust construction, thoughtful two-start design, and adherence to standard metric dimensions. It’s a dependable choice for professionals who value consistent thread quality, easy initiation, and durable performance in general-purpose tapping projects.
