Integral structure that does not use the O-ring. Compared to the two-piece structure sealed with O-rings, the Hydraulic Chuck gains stable precision and high rigidity. Further, the runout accuracy is greatly improved by short projection length and the dual oil pressure points.

Short projection length. It is suitable for machining processes that require high runout accuracy, for burnishing drills/reamers, ball end mills, end mills, diamond reamers and grinding tools.
