Abstract: In preferred form, a hydraulic toolholder for retaining an elongated cutting tool in fixed relationship to the peripheral edge of a rotatable cylindrical metal billet for peeling a thin metal strip. The cutting tool is retained in recess in the body portion of the toolholder by a pivotal clamp member which is tightly drawn against the cutting tool by a cam-carrying wedge engaging a shaft interconnected with the clamp member. Hydraulic pressure alternately acting against opposite sides of a piston moves the interconnected wedge into and out of engagement with the shaft to clamp or unclamp the cutting tool.
