Hydraulic Chucks

Highly Accurate Tool Holders


Hydraulic Chucks are ideal tool holders for machining processes that require high accuracy such as drills, reamers, ball mills, end mills, diamond reamers and grinding tools. With a wide variety of tool diameters and projections to fit any application, they are also available for simultaneous fit systems and all other major interfaces. Hydraulic Chucks are the perfect tool holder for high precision machining in automotive, aerospace, medical, and die & mold.

High Precision Runout Accuracy Less Than 00012" (3µm)





High precision runout accuracy less than .00012" (3µm) at 4xD improves the work piece surface finish and extends tool life. Repeatability is less than .00006" (1.5µm).
    


Integral Sleeve Construction Makes the Difference for Precision and Rigidity






Compared with the traditional two-part construction sealed with O-rings, BIG Hydraulic Chucks are long lasting and maintenance free. Also, the rigidity is greatly improved by the short projection length and dual pressure points.
