• Use lubrication suited to the work material and keep the working area clean for stable results.
• Inspect the produced thread with an appropriate method when the application is safety relevant.

Note Clean the functional surfaces after use and store the product protected from contamination.

• Supports repeatable thread production in machining processes
• Suitable for series work with controlled alignment and lubrication
• Helps maintain thread quality when process parameters are stable
• Practical for production and maintenance machining

• Requires stable setup and suitable chip evacuation for the tap design
• Not intended for aggressive high speed use without validated cutting data

1. Prepare the workpiece correctly, including core hole or lead in preparation as required.
2. Apply lubrication suitable for the work material and process.
3. Mount the tool in a suitable holder or wrench and ensure straight alignment.
4. Start the thread carefully and maintain stable guidance during engagement.
5. Remove chips and debris as needed so cutting edges remain free.
6. Stop if resistance increases unexpectedly and check alignment and lubrication.
7. After threading, clean the thread and protect the tool for storage.

How do you choose the correct tool variant?
Match the thread system, designation, and execution stated in the product name to your drawing requirement and work material. Select the correct tool type for manual or machine use.

Which holder or wrench do you typically need?
Hand taps typically use a tap wrench. Dies typically use a die holder. Machine taps use a suitable machine holder with controlled alignment. Confirm details by the execution stated in the product name.

How do you reduce the risk of tool breakage?
Use correct preparation, stable alignment, suitable lubrication, and controlled torque. Stop if resistance rises unexpectedly and remove chips and debris as required.

How do you maintain thread quality in practice?
Keep preparation consistent, align the tool straight, use lubrication suited to the material, and verify threads with an inspection method appropriate for the application.
