Threading tool NEO tools 12-915 709 g

The NEO tools 12-915 threading tool set weighs 709 g and includes a complete selection of HSS hand taps and dies for creating metric threads from M3 to M12. Packaged in a metal case, the set contains 32 pieces: a full range of taps and dies in sizes M3, M4, M5, M6, M8, M10 and M12, a thread gauge and a screwdriver for fastening dies. Components intended for cutting (taps and dies) are manufactured from high-speed steel (HSS) while the gauge and screwdriver are made from 45# steel, providing a balance of cutting performance and durable handling.

Advantages

The set provides a wide size range for common metric threads and comes complete with accessories needed to mount and check dies, offering practical workshop-ready storage in a metal case. HSS cutting elements deliver wear resistance and maintain cutting edges when used correctly, while the 45# steel gauge and screwdriver provide stable clamping and simple adjustment. The compact and organized layout of the case helps keep tools accessible and protected during storage and transport.

Suitable for

• Cutting and repairing internal threads in metals and alloys
• Forming external threads on rods and shafts using dies
• Maintenance and mechanical workshop tasks
• Locksmith and fitting operations requiring metric threads M3–M12
• DIY projects that require reliable thread cutting and repair

How to use

Select the correct tap or die size for the required metric thread (M3–M12). Secure the workpiece in a vise or appropriate holder to prevent movement. For internal threads, apply cutting fluid or lubricant to the tap, insert it squarely into the hole and rotate evenly, reversing periodically to break chips. For external threads, mount the selected die into the die holder, align it with the rod, apply lubricant and turn steadily, maintaining alignment to produce even threads. Use the thread gauge to verify pitch and profile, and the screwdriver to fasten or adjust dies in the holder as needed. Clean chips and swarf from tools and threads after use.

Recommendations

Use appropriate cutting fluid for the material being machined, work at moderate speed and avoid excessive force to prolong HSS tool life. Store tools dry in the metal case to prevent corrosion and inspect cutting edges regularly; replace or regrind worn taps and dies to maintain thread quality.
