Description
Version:
- Long version.
- Torque transmission via the square shank.
- The leading end of the extension is fitted with a quick-release chuck.
- The rear end of the extension is to DIN, so that the extension can be mounted either in a quick-change tapping head or in an ER collet for taps with a square shank.
Advantage:
- Time-saving exchange of taps with repetition accuracy and quick-change adapter.
- Almost any combination of extensions available, due to the identical diameter D3 and drive square K2.
Application:
For tapping in confined places, such as recesses, offsets, sharp edges on jigs, extremely deep internal threads, or directly into casting walls.
Suitable for:
For mounting in quick-change tapping collets or ER tapping collets with a square drive.
