Description
Version:
- Long and extra long version.
- The front end of the extension acts as a collet. The collet is clamped to the tap by hand-tightening the knurled clamping nut.
- The drive torque is provided by the square drive.
- The rear part of the extension is to DIN, so that the extension can be mounted in quick-change tapping collets or ER tapping collets with a square drive.
Application:
For tapping in confined places, such as recesses, offsets, sharp edges on jigs, extremely deep internal threads, or directly into casting walls.
Note:
Alternative hexagon collet for fixing the tap available on request.
