Centerdrill collet chuck

Due to the extreme thermal fluctuation and radial load, it is absolutely essential to use our special collet
chuck. The heat generated during the flow drilling process must not be allowed to enter the machine
spindle but it must be cooled instead. Commonly available three-part chucks may cause the breakage
of the Centerdrill if it is not clamped centrally! For this reason, a collet chuck with a cooling ring was
developed, especially for the flow drilling process with Centerdrill, so that the heat can be dissipated
ideally and a secure connection can be ensured. The collet chuck MT2 is standard for the Centerdrills with
a shank up to Ø 14mm. For bigger sizes, we recommend a MT3 or MT4 collet chuck with a cooling ring.

Your advantages:

Heat dissipation through a special cooling ring and thus, ensuring the protection
of your machine spindle
A secure clamping and concentricity of the Centerdrill tools ...
... and thereby, a lower risk of breakage of the Centerdrill tools

If you are interested in a collet chuck, we also recommend having a look at our Beginner Set. This will pro-
vide you complete basic equipment, with a cost advantage compared to the single purchasing. Page 56.
