Hydraulic Chuck

The Hydraulic Chuck is of mono-block construction incorporating a clamp sleeve into the body. Compared with conventional two-piece models that use O-rings for sealing, the metal contact structure ensures high rigidity with stable accuracy.

The Hydraulic Chuck has two hydraulic chambers that can secure each side of a knife at two points and the protruding length not actually chucking the knife shell is so short that the Hydraulic Chuck has improved runout accuracy.
