Precise - Constant concentricity and repeatable accuracy 3µm
at distance 3xD (max. 50 mm). Pure axial clamping of the collet by means of a clamping sleeve and clamping nut result in no torsion moments.

Simple - Clamping by means of a hexagon T-Key - Opening by means of our patented ejection mechanism (no eccentric) permits a quick and easy tool and collet change on the machine spindle or in your hand. The collet is only shifted axially. There are no radial forces to have a negative influence on the concentricity.

Unique - Patented mechanical clamping wedge clamping forces up to 300.000 N can be produced by hand, which increase with higher speeds and at the same time the mechanical construction ensures high durability.

The Precision Collet HP+ has a surface roughness of Rz 1.6µm on the external contour, which is a prerequisite for generating the high clamping forces. Because of the high forces the individual elements form a concentric unit with exceptionally low runout and high stiffness.

Temperature Stability - Suitable for dry processes and hard milling up to 200° Resistent to temperature changes

Vibration - possible vibrations during the application are absorbed
by the collet

Economical - Stiffness and constant high concentricity result in up to 5 times higher tool life at the cutting tool, which results in increased machine running times and reduced set-up costs

Sealed - Internal cooling and sealing up to 80 bar.
Sealed against any ingress of dirt and chips into the chuck - Different seal executions for cooling along the chuck.

Safe - Clamping forces of 300 Nm and more can be produced by hand

Clamping torque - The transferable torque moments are shown in the diagram below:
We recommend using a torque wrench to guarantee safe clamping
