Short Machine Tap DIN 352 Form B HSSE - M 12 x 1.75

• Create metric ISO internal threads in steel and comparable alloys, depending on the workpiece condition and cutting fluid.
• Use when you want predictable thread geometry for assembly without additional forming steps.
• Often selected for through holes where chips can move forward through the bore, depending on the setup.
• Applied in repair and production environments where you need repeatable thread quality for assembly.
• 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 Align the tool to the hole axis, use appropriate lubrication, and clean the thread after tapping to avoid assembly issues.

• Compact tool length supports space limited setups
• DIN 352 reference supports consistent tool selection
• HSSE tool material supports stable cutting edges
• Form designation supports predictable thread entry behavior
• Metric ISO thread focus supports common fastener systems

• Not suitable for very hard or highly abrasive materials, depending on execution
• Not intended for high performance tapping without rigid guidance and controlled coolant

1. Confirm the required thread specification before you start.
2. Create a clean pilot hole and ensure enough depth for the thread.
3. Secure the workpiece and align the tool axis to the hole.
4. Clamp the tap in a suitable holder.
5. Apply suitable lubrication for cutting.
6. Tap with controlled feed and avoid sudden speed changes.
7. Stop if you notice abnormal torque and clear chips.
8. Remove the tap, clean the thread, and verify fit.

Why would you choose a short machine tap for internal threading?

A short machine tap supports compact setups and stable tool guidance in many holders. It is practical when you want efficient tool handling and repeatable internal threads.

How do you choose between Form B and a spiral flute execution?

Form B is often selected when chips can move forward through the hole. Spiral flute executions are commonly selected when you want chips transported back toward the entry, depending on hole type and process strategy.

Can you use the tool in the size M 12 x 1.75 by hand and in a machine?

Yes, depending on your holder and setup you can drive the tool by hand or with a machine. Focus on alignment, lubrication, and controlled torque to protect the cutting edges.

Can you use the tool for re tapping an existing thread?

Yes, depending on thread condition you can use it to clean up damaged flanks. Keep torque low and stop if the tool binds, because the cutting edges are not made for removing large amounts of material.

How do you choose the correct pre drilled hole for tapping?

Use a drill size recommendation that matches the thread and tolerance requirement. Use a chart from your process documentation or the manufacturer, and avoid guesswork.

Where can you find technical background on short machine taps and selection criteria?

Use this document for selection guidance and general process parameters: Technical information short machine taps as PDF.

What lubrication should you use for thread cutting?

Use a cutting fluid suitable for the workpiece material and the tapping method. Stable lubrication supports surface quality and helps control torque.
