FAQs
What thread sizes are included in this set?
The set includes dies for standard metric threads M3x0.5, M3.5x0.6, M4x0.7, M5x0.8, M6x1.0, M8x1.25, M10x1.5, and M12x1.75. It also includes duplicates of each size for more extensive use.
Is this set suitable for imperial threads?
No, this set is specifically designed for metric thread sizes only.
What is the material of the dies and taps?
The dies are made from heat-treated alloy steel for durability and performance.
How do I properly use a die to cut external threads?
Select the correct die for your material diameter. Apply cutting fluid. Place the die onto the end of the rod, ensuring it is square. Turn the die holder clockwise, applying steady pressure. Back the die out periodically to clear chips and reapply lubricant.
What is the purpose of the screw/pitch gauge?
The screw/pitch gauge is used to accurately measure the number of threads per inch (for imperial) or the pitch (distance between threads, for metric) of an existing screw, bolt, or tapped hole. This ensures you select the correct die or tap.
Can I use this set for cutting threads in hard metals?
The heat-treated alloy steel construction makes the dies suitable for cutting threads in many common metals. However, for extremely hard metals, additional lubrication and slower speeds may be necessary, or specialized tooling might be required.
How should I maintain the tools for longevity?
Clean all tools after use, dry them thoroughly, and apply a light coat of oil to prevent rust. Store them in the provided tin in a dry location.
Troubleshooting
Die not cutting threads cleanly
Ensure you are using the correct size die and applying sufficient cutting fluid. Check that the die is properly seated and tightened in the die holder. Start the threading process slowly and with steady pressure.
Tap breaks during use
This often occurs due to applying too much force, not using cutting fluid, or trying to tap a hole that is too small or obstructed. Ensure the tap is aligned straight with the hole and back it out periodically to clear chips.
Dies or taps are rusting
Clean the tools thoroughly, ensure they are completely dry, and apply a light coating of oil before storing them. Store in a dry environment.
Difficulty identifying thread pitch
Use the included screw/pitch gauge to accurately measure the existing thread or the material you intend to thread. Match the thread profile on the gauge to your target.
Pros and Cons
Pros
- Provides a wide range of metric and metric fine thread sizes.
- Constructed from durable, heat-treated alloy steel for extended tool life.
- Includes essential tools like a tap wrench, die holder, and pitch gauge.
- Comes in a protective metal tin for storage and portability.
- Suitable for both professional workshops and occasional use.
Cons
- Metal storage tin may allow dies to shift if not packed carefully.
- Primarily metric, not suitable for imperial thread sizes.
- Requires user knowledge of tap and die techniques for effective use.
Setup, Compatibility & Care
Setup: Ensure the desired die is securely locked into the die holder using its set screws. Similarly, insert the tap into the tap wrench. Always apply appropriate cutting fluid or oil when tapping or threading to reduce friction, prevent galling, and extend tool life.
Compatibility: This set is designed exclusively for cutting and repairing *metric* threads. It covers standard metric sizes from M3 x 0.5mm pitch up to M12 x 1.75mm pitch, including metric fine thread variants.
Care: After each use, clean the dies and taps thoroughly to remove debris and cutting fluid. Apply a light coat of oil to prevent rust. Store the components securely in the provided metal tin, ensuring they are organized to prevent damage. Periodically check the set screws on the tap wrench and die holder for tightness.
