ABSTRACT:
A cutting tool having a main body with a longitudinal axis and one or more slide receiving slots. A cutter carrying slide is slidably received within the slide receiving slot in the body for sliding movement relative to the body along a first slide path extending generally normal to the longitudinal axis. A slide positioning member is provided for shifting the cutter carrying slide along the slide path between a retracted position and a cutting position. An anti-backlash device is also provided for establishing and maintaining firm contact between opposing surfaces of the slide and the slide positioning member during movement of the slide toward the cutting position. The anti-backlash device increases force urging the opposing surfaces into contact with each other as radial displacement increases between the slide and an axis of rotation. The anti-backlash device can include opposing first and second cam surfaces carried by the slide and the main body that engage with one another as the slide moves toward the cutting position. A biasing member can be provided for urging one of the cam surfaces toward the other cam surface.
