A workholding apparatus including a body and a drive member carried by the body, so that the drive member and body partially define a fluid chamber therebetween for containing a fluid. A driven member is also carried by the body and includes multiple displacement reliefs therein. An intermediate member with a displacement relief is received between the drive and driven members. The intermediate member prevents the drive member from extruding through the displacement reliefs in the driven member under fluid pressures of the fluid, thereby enabling use of the apparatus under higher performance applications that would not be possible without the intermediate member.
