COLLET CHUCKS 457 WITH HIGH TIGHTENING TORQUE FOR DIN 6499 (ER) COLLETS

The Mexin 457 collet chuck is nowadays the best alternative to the other systems (by deformation or hydraulic).
Thanks to mechanical elements we get an axial (frontal) movement of the collet towards the nut.

In that way the radial and torsion effort supported by the collets in most of the collets of the market is suppressed.



Advantages:
  - Elimination of radial and torsion tension on the collets.
  - High fastening strength of the chuck >300Nm in a 20mm Ø, with a tightening torque of 12Nm on the wrench.
- Use of DIN 6499 (ER) collets, allowing a wide variety of uses.
  - Thanks to their design we could reduce the body volume, getting a bigger stability in that way.


The Mexin 457 collet chuck model AD + B has an internal coolant supply.
For a collet chuck with internal coolant supply, use the sealed collet ref. 80.479.
