Product Information
Full details
This OKODOKO Metric Tap and Die Set, featuring an M12 x 1.5mm thread size, is designed for DIY enthusiasts and professionals needing to create or repair internal and external threads. Its key benefit lies in its precision threading capabilities for alloy steel, die steel, cast iron, and various metals, perfect for maintenance and repair. A caveat is that the round die requires a separate die wrench for secure use.

FAQs
What is the difference between a tap and a die?
A tap is used to create or repair internal threads (like in a hole), while a die is used to create or repair external threads (like on a bolt or rod).
Do I need a special wrench for the die?
Yes, the round die requires a die wrench (not included) to grip and turn it effectively. The wrench has a screw to secure the die in place.
Can I use this set on hardened steel?
The set is designed for alloy steel, die steel, cast iron, and general ferrous and non-ferrous metals. Performance on extremely hardened steels may vary and could require specialized tooling or techniques.
What size pilot hole should I drill for the M12 x 1.5mm tap?
For an M12 x 1.5mm tap, you typically need to drill a hole slightly smaller than the minor diameter of the thread. For a standard M12 x 1.5mm tap, a pilot hole of approximately 10.5mm is generally recommended, but always consult a tap drill chart for precise recommendations based on material.
How important is using tapping oil?
Using tapping oil is highly recommended. It lubricates the cutting edges, reduces friction and heat, helps clear chips away, and significantly improves the quality of the threads while extending the life of the tap and die.
Can these tools be used for blind holes?
Machine taps are generally suitable for through holes. While they can be used in blind holes, care must be taken to manage chip evacuation and ensure the tap doesn't bottom out before the full thread depth is achieved. Specialized 'bottoming' taps are designed specifically for blind holes.
What is the material of the tap and die?
The machine tap is made of high-speed steel (HSS) for good hardness and wear resistance, while the round die is made of alloy tool steel for durability and abrasion resistance.
Troubleshooting
Tap or die not cutting threads cleanly
Ensure you are using adequate lubrication (tapping oil). Verify the pilot hole size is correct for tapping. Check that the tap or die is sharp and not damaged. Use a slower, consistent speed when threading.
Tap breaking during use
Excessive force or misalignment can cause taps to break. Ensure the workpiece is securely held and the tap is entering the hole straight. Reduce the cutting depth per pass, especially in harder materials. Use tapping oil.
Die not starting a thread properly on a bolt
Ensure the end of the bolt is chamfered slightly to help the die start. Use a starting die if available for a cleaner initial cut. Apply steady, even pressure and lubrication.
Difficulty securing the die in the wrench
Ensure you are using a die wrench that is the correct size for the die. Make sure the die is oriented correctly within the wrench and that the fastening screw is engaging properly with the die's slot.
Pros and Cons
Pros
- Durable construction with high-speed steel and alloy tool steel.
- Precise thread creation for professional results.
- Suitable for a wide range of common metals.
- Designed for both new thread creation and repair.
- Machine tap is compatible with various power tools.
Cons
- Die wrench is not included and must be purchased separately.
- Primarily designed for through holes, may require adaptation for blind holes.
- Requires user knowledge of thread tapping and die cutting processes.
- Tapping oil is recommended for optimal performance and tool longevity, adding an extra purchase requirement.
Setup, Compatibility & Care
Setup:
- Die Setup: To use the round die, it must be inserted into a compatible die wrench (sold separately). Secure the die by inserting the wrench's fastening screw into the die’s designated slot and tightening it.
- Tap Setup: The machine tap is designed for use with drill presses, tapping machines, CNC machines, and milling machines. Ensure the tap is securely held in the machine's chuck or holder.
Compatibility:
- Thread Size: Specifically designed for M12 x 1.5mm metric threads.
- Materials: Compatible with alloy steel, die steel, cast iron, and both ferrous and non-ferrous metals.
- Machines: Suitable for use with standard machining equipment designed for tapping and threading.
Care:
- Lubrication: Always apply appropriate lubricating or tapping oil to the cutting edges of both the tap and die before and during use. This significantly enhances thread quality and extends tool life.
- Cleaning: After each use, thoroughly clean the tap and die to remove any metal chips or residue. Store them in a dry environment to prevent corrosion.
- Storage: Keep the tools in their original packaging or a protective case to avoid damage and maintain their sharpness.
