Title: Toolholder having a clamping arm and a spacer for preventing overclamping

Abstract: A toolholder for holding a cutting insert, particularly for grooving and/or parting operations. The toolholder comprises a base and a clamping arm forming therebetween a pocket and a slot. The pocket is open at a front end thereof for receiving the cutting insert, and the slot extends rearwardly from a rear end of the pocket. A fastening screw extends through the slot from the clamping arm to the base for displacing the clamping arm toward the base in order to clamp the cutting insert within the pocket. A spacer is disposed in the slot for limiting an extent of movement of the clamping arm toward the base, thereby preventing overclamping of the clamping arm.
