Round Die DIN 223 (DIN EN 22568) HSS - M 2.5 x 0.35 | VÖLKEL
Round Die DIN 223 (DIN EN 22568) HSS - M 2.5 x 0.35
You produce external threads in workshop operations with a round die. It is a compact option for service work and prototyping where you need repeatable manual control.
Match the die to your thread requirement and clamp it securely in a round die holder. Start square to the workpiece axis and use lubrication to reduce friction and wear.
- Cut external threads on rods, bolts, and studs in repair, prototyping, and small batch work.
- Use with a round die holder or die stock to keep the die square to the workpiece axis.
- Apply cutting fluid matched to your material to reduce friction and protect the thread profile.
- Process: manual driving or assisted driving depending on your holder and machine setup.
- Use: thread cutting, re tapping, and thread cleaning depending on condition.
Note Confirm thread system, pitch, and fit requirement before cutting. Prepare the workpiece with a clean lead in chamfer.
- Practical for workshop thread cutting without dedicated thread rolling equipment.
- Direct feedback on cutting load during manual use.
- Simple setup with standard die holders.
- Enables maintenance work on damaged external threads.
Drawbacks
- Performance is limited in very hard or abrasive materials unless a suitable die execution is selected.
- Cycle time is limited for high volume production compared with dedicated machine processes.
- Inspect the workpiece and ensure there is a clean lead in chamfer at the thread start.
- Select a round die holder and clamp the die securely before you approach the workpiece.
- Apply cutting fluid to the workpiece area and to the die entry side.
- Align the die square to the workpiece axis and start cutting with steady forward pressure.
- Turn the die forward to advance the thread while maintaining alignment.
- Reverse briefly at intervals to clear chips from the cutting edges.
- Continue until the required thread length is reached and then stop the forward feed.
- Back the die off the workpiece and remove it from the holder.
- Clean the die and verify the thread fit with a matching part or a suitable gauge.

- How do you select the correct die for your thread?
- Match the thread designation in the product name to your required external thread and ensure the mating nut or component uses the same system and pitch.
- Which holder should you use for a round die?
- Use a round die holder or die stock that clamps the die securely and supports square alignment to the workpiece axis.
- Which workpiece preparation is important before cutting an external thread?
- Prepare a clean lead in chamfer and ensure the workpiece surface is free of scale and burrs so the die can start square and cut cleanly.
- How do you manage chips during external thread cutting?
- Use suitable cutting fluid and clear chips regularly during the operation so chips do not score the new thread surface.
