Machine Nut Tap DIN 357 HSSE - M 12 x 1.75
You produce threaded nuts with a machine nut tap in a controlled machining process. The tool supports consistent thread geometry when the setup and lubrication are stable.
Match the tap to the nut thread requirement and use a stable machine holder for alignment. Keep lubrication consistent and remove chips to avoid scoring and oversize threads.
- Produce internal threads in nuts and similar short components in mechanical engineering and maintenance.
- Typically used in a machine tool with a suitable tapping chuck or tool holder for controlled feed.
- Best suited for through holes where chip evacuation is reliable, depending on flute form.
- 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 Clamp the nut securely and align the tool to avoid cross threading. Use a stable feed to control chip load.
- Supports series production of threaded nuts with consistent geometry.
- Machine driven operation reduces operator variability compared with manual tapping.
- DIN based execution supports standardized selection.
- Tool change is quick in common machine holders.
Drawbacks
- Chip evacuation limits performance in blind holes unless the tool design is specified for that condition.
- Requires stable machine alignment and suitable lubrication to avoid thread damage.
- Prepare the part so the hole is drilled and deburred and the start is chamfered.
- Clamp the nut or component securely in the fixture so it cannot rotate.
- Mount the tap in a suitable machine holder and set a controlled feed and stop position.
- Apply cutting fluid to the tool and to the hole entry area before you start.
- Start the tapping cycle and monitor load for signs of misalignment or chip packing.
- Stop the cycle and retract the tap according to your machine sequence.
- Clean the thread and remove chips from the part and the tool.
- Check thread fit with a matching screw or with your inspection method.

- What is a machine nut tap used for?
- It is used to cut internal threads in nuts and similar short parts, typically in through holes where chips can evacuate reliably.
- Which holder is suitable in a machine tool?
- Use a suitable tapping chuck or rigid tool holder that keeps the tap aligned to the hole axis and supports controlled feed.
- Can you use a machine nut tap for blind holes?
- Blind hole use depends on tool geometry and chip evacuation, so confirm that the tap execution is specified for your hole type before you run the process.
- What should you monitor during machine tapping?
- Monitor torque and sound, and stop if you see signs of misalignment, chip packing, or insufficient lubrication.
