This HARDEN Hand Tap and Dies Set is designed for mechanics and DIY enthusiasts needing to create or repair threads. Its key benefit is providing a comprehensive selection of common metric sizes (M3-M12) in a portable metal case, making it ideal for workshop environments. A minor caveat is its weight, which is substantial due to the full metal construction.

The set includes taps and dies for M3, M4, M5, M6, M8, M10, and M12 metric thread sizes.
The three-stage tapping system helps to start the thread more cleanly and makes the tapping process smoother, reducing the risk of tap breakage and improving thread accuracy.
While the taps and dies are designed for durability, performance on very hardened steel may vary. Always use appropriate cutting fluids and techniques. For extremely hard materials, specialized tools might be required.
The set comes with a durable metal case. Ensure all taps and dies are cleaned and lightly oiled before storing them in their designated slots within the case to prevent rust and maintain organization.
It is recommended to use a dedicated cutting fluid or oil designed for metalworking. This helps to reduce friction, cool the cutting edge, and clear away metal chips.
This set is designed for standard right-hand threads. It does not include tools for left-hand threads.
The set weighs approximately 3.05 pounds (around 1.38 kg).
Ensure you are using adequate lubrication, not forcing the tap, and rotating it correctly (usually 1.5 turns forward, 0.5 turns back to clear chips). Verify the material hardness is appropriate for the tap.
Check that the correct die size is being used. Ensure the die is sharp and clean. Apply sufficient cutting fluid and apply even pressure.
Increase lubrication. Ensure the tap or die is starting straight and perpendicular to the workpiece. Use the three-stage tapping method if applicable.
Apply more cutting fluid. Gently try to back the tool out by rotating it in the reverse direction. If severely stuck, consider drilling out the workpiece.
Setup: Select the appropriate tap or die for the desired thread size. For tapping, insert the tap into a tap wrench and ensure it is perpendicular to the workpiece. For die cutting, insert the die into a die stock. Apply cutting fluid or oil to the tool and workpiece to facilitate cutting and prolong tool life.
Compatibility: This set is designed for creating and repairing standard metric threads within the M3 to M12 range. It is compatible with most common metals such as steel, aluminum, and brass.
Care: After each use, clean the taps and dies thoroughly to remove metal shavings and cutting fluid residue. Apply a light coat of oil to prevent rust. Store all components back in their designated slots within the metal case to maintain organization and protect the tools.
