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 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.

h6 shank with Weldon flat for use in Weldon/shrink-fit chucks or hydraulic chucks.

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.
