Abstract
A rotatable cutting tool has a shank portion for coupling to a tool driving device and a cutting portion to which is attached at least one support member for retention of a replaceable cutting element. The support member is so arranged to permit displacement of at least the portion thereof retaining the cutting element whereby the position of the cutting element relative to the body of the cutting tool may be changed by such displacement. A totally enclosed hydraulic force multiplier is mounted within an internal cavity of the cutting tool. The force multiplier is responsive to a control force to effect the displacement of the support member, the control force advantageously supplied by application of pneumatic pressure.
