Hand Tap Rougher DIN 2181 HSS-G - M 12 x 1.25 | VÖLKEL
Hand Tap Rougher DIN 2181 HSS-G - M 12 x 1.25
This hand tap supports manual thread cutting in a wide range of workshop tasks where machine access is limited.
Check that your hole preparation and holder setup match the tool style, since misalignment is a common cause of poor thread quality. M denotes ISO metric thread designation used for common metric screw threads in machine building and maintenance. HSS-G indicates a ground high speed steel tool, typically selected when edge definition and repeatability matter.
- Cut internal threads in components used in mechanical engineering and plant service.
- Process: manual driving or assisted driving depending on your holder and machine setup
- Use: thread cutting, re tapping, and thread cleaning depending on condition
- Use stable workholding, because movement during the start often causes oversize threads.
Note Use cutting fluid suitable for the work material and keep the tool aligned during the first turns.
- Supports consistent internal threading when alignment is correct
- Usable across common workshop and maintenance processes
- Helps reduce rework through repeatable tool geometry
- Allows controlled fit when you choose the correct thread designation
- Helps keep thread quality stable when you use appropriate lubrication
Drawbacks
- Sensitive to misalignment, especially during the first turns
- Requires careful handling to avoid edge damage in busy shop environments
- Prepare the hole and remove burrs so the tool starts straight.
- Clamp the workpiece securely and align the tool to the hole axis.
- Use a suitable holder or drive and apply cutting fluid for the work material.
- Start the thread with controlled feed and keep the tool guided through the first turns.
- Continue with steady torque and clear chips from the cutting area as needed.
- Reverse to remove the tool, then clean the thread and the tool flutes.
- Check the thread with the intended fastener or a suitable gauge and protect the part.
- 1 piece Hand Tap Rougher DIN 2181 HSS-G - M 12 x 1.25
- Product type: Hand Tap
- Standard: DIN 2181
- Thread designation: M
- Tool material: HSS-G
- How do you select the correct thread designation for this product
- Match the thread designation in the product name to the mating fastener or component standard, then confirm that your workpiece material and process setup suit the tool type. If you work with mixed standards, separate your tooling by thread family to avoid mix ups.
- What holder or drive concept do you need
- Use a holder that clamps the tool concentrically and supports straight alignment to the workpiece axis. For manual work, choose a stable hand drive that lets you feel torque changes. For machine use, verify reverse capability and consistent feed.

- Which hole preparation checks matter most
- Prepare the entry edge, remove burrs, and keep the hole clean so the tool starts straight. In blind holes, confirm that there is enough depth for the tool lead and chip space. In through holes, support chip evacuation out of the exit side.
- How do you reduce the risk of misalignment
- Start the tool with the axis visually aligned, then guide it through the first turns with low torque. Use stable workholding and avoid side load. If a thread feels tight early, remove the tool, clean chips, and inspect the entry.
- Can you use this in repair work
- Yes, for many workshop repairs you can use the tool to restore a usable thread when the base material is still intact. Clean damage first and avoid forcing, since distorted threads can increase torque and edge wear. For heavily stripped threads, a thread repair insert system can be the better option.
