Hand Tap Rougher DIN 2181 HSS-G - M 11 x 1.25

• cutting or reworking internal M 11 x 1.25 threads where the drawing or mating part requires this designation
• The rougher starts the thread and removes the first material portion before the later tap stages continue the profile.
• right hand thread work in manual tapping setups
• selection by DIN 2181 tool dimensions
• 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 Match M 11 x 1.25, tap stage, holder fit, and hole preparation before cutting.

• HSS-G cutting material is stated in the product data and supports selection by material execution
• DIN 2181 dimension reference helps compare the tool with drawings and stock systems
• tolerance class ISO2 (6H) gives a defined selection reference
• The rougher starts the thread and removes the first material portion before the later tap stages continue the profile.
• manual use supports controlled correction when machine feed is not the preferred method

• The tool is only correct for M 11 x 1.25 and the stated tap stage; choose another item from Threading tools if the thread or stage differs.

1. Compare M 11 x 1.25 with the drawing and the mating component before you start.
2. Clamp the workpiece securely and prepare the hole according to your shop process.
3. Fit the tap in a holder that supports straight manual guidance.
4. Cut with the hand tap rougher and keep the tool aligned with the hole axis.
5. Use cutting lubricant suitable for the material being machined.
6. Withdraw the tool carefully and clear chips from the flutes and hole.
7. Inspect engagement with the mating part or gauge method required by your process.

Which exact thread is this product for?

This product is for M 11 x 1.25. Metric thread selection is based on nominal diameter and pitch, so both values must match the screw connection or drawing.

Is this product for internal or external threads?

This product is for internal threads. Use a round die when the workpiece needs an external thread.

How do you choose the correct tap stage?

Choose the stage by the manual tapping sequence. The rougher starts the thread and removes the first material portion before the later tap stages continue the profile.

What should be checked before ordering?

Check thread system, size, pitch, standard, tolerance class where specified, and tap stage against the drawing or existing component.

Where can you find technical background for hand taps?

Use the Technical information hand taps as PDF.

Can this product be used for repair or thread cleaning?

Use it for re tapping or cleaning only when the existing internal thread is M 11 x 1.25 and the thread condition still allows controlled cutting.

How do you avoid selecting the wrong pitch?

Compare nominal diameter and pitch together because similar nominal diameters are not interchangeable when the pitch differs.
