drill chuck / hydraulic / expandable

Clamping mandrels SDH are suitable for small workpiece diameters.

The clamping mandrel SDH has the advantage of gentle application of the centring force, one of the secrets of the low deformation hydraulic STIEFELMAYER clamping principle.

As with other clamping chuck types, the segment clamping jaws are
controlled separately, resulting in as little deformation as possible of the
machined workpieces.

Technical features:

inside clamping
clamping diameter approx. 45 mm to 100 mm
excellent re-run accuracy
