Tap Extension 13.0 mm

• extending tap reach in deeper or less accessible internal threading positions
• connecting a tap and a driving tool where the square size matches the setup
• manual or assisted tapping setups that require additional reach
• maintenance and assembly work where direct holder access is limited

Note Use the extension only with matching square dimensions and avoid side loading during tapping.

• DIN 377 reference supports selection by established holder dimensions
• stated working range 13.0 mm gives a factual basis for size matching
• extension design helps transfer torque to a tap in deeper or restricted positions

• The accessory works only when the tool dimensions match; choose a different holder size in the Threading tools category if the fit is not correct.

1. Compare the tap square and extension size before assembling the setup.
2. Insert the tap into the extension until the drive faces are fully seated.
3. Connect the extension to the selected driving tool.
4. Align the complete setup with the hole axis before applying torque.
5. Turn steadily and keep side forces as low as possible during the operation.
6. Disassemble the extension after use and clean the drive faces.

Question: What is this tap extension used for?

Answer: It extends the reach between the tap and the driving tool in deeper or restricted internal threading positions.

Question: How do you select the correct extension?

Answer: Select the extension by the square size and the working length required by the application.

Question: Does the extension cut the thread itself?

Answer: No. The tap cuts the thread, while the extension transfers torque to the tap.

Question: What should be checked before use?

Answer: Check square fit, alignment, holder connection, and access before torque is applied.

Question: Can the extension be used in narrow assemblies?

Answer: Yes, when the dimensions match and the complete setup can stay aligned without side loading.

Question: Where can you find the holder and threading tool catalog?

Answer: Use the VD 23 catalog as PDF.
