Round Die DIN 223 (DIN EN 22568) HSS - M 38 x 1.5 LH

This die is the optimal choice for a wide range of applications where a left-hand turn is required. Its most important features that set it apart are:

• Left-Hand Thread (LH): Indispensable for applications where a right-hand thread would loosen by itself due to the rotating motion of the component, such as on certain axles or shafts.
• Standard DIN 223 (DIN EN 22568): This standard guarantees standardized production with precise dimensions for reliable thread quality.
• HSS Material: High-Speed Steel is robust and wear-resistant, ideal for use in machinable materials.
• 6g Tolerance: This tolerance class is the standard for metric threads. It ensures that the cut thread has a good fit.

To achieve optimal results, follow this simple guide:

1. Step 1: Prepare the workpiece. Choose a round rod with the correct outside diameter (38 mm). The end face should be chamfered to facilitate the cutting process.
2. Step 2: Prepare the tool. Clamp the die into a suitable die stock (handle). Make sure the cutting edges are clean and undamaged.
3. Step 3: Prepare lubrication. Apply a suitable cutting oil to the workpiece. This reduces friction, minimizes heat generation, and extends the die's service life.
4. Step 4: Cut the thread. Place the die perpendicularly onto the workpiece and turn it slowly with even pressure counter-clockwise. Make sure you start the die straight to avoid a crooked thread.
5. Step 5: Clean. Once the thread is cut, carefully clean the workpiece and the die of any chips.

Q: What is a left-hand thread and when is it used?

A: A left-hand thread is used when a right-hand thread would loosen by itself due to the movement of the component. A classic example is bicycle pedals, whose threads are turned in opposite directions to prevent them from coming loose when pedaling.

Q: How do I identify a left-hand thread die?

A: Left-hand thread tools are usually marked with an "LH" (Left-Hand) or have a special ring marking. This die has the marking M 38 x 1.5 LH directly on the tool.

Q: What is the difference between a fine thread and a standard thread?

A: A fine thread has a smaller pitch (thread spacing) than a standard thread. This results in a higher load-bearing capacity, a better sealing effect, and greater resistance to vibration. However, it is more sensitive to damage.

Q: What should the outer diameter of my rod be?

A: The starting diameter of the rod should correspond to the nominal diameter of the die, which is 38 mm. To make cutting easier, the diameter can also be slightly smaller.

Q: How do I prevent a crooked thread?

A: Make sure to place the die absolutely straight on the workpiece. A die guide bushing in the die stock can help you with this. Begin the cut with light but even pressure.
