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 transmitted via 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 inaccessible 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.
