Abstract
A cutting device comprising a cutting insert and a holding part with a beam part, extending in a longitudinal direction, and a clamping head, which projects beyond an upper side of the holding part with a projection, wherein the projection is connected to a first of two clamping fingers which between them form a receiving pocket for receiving the cutting insert. A clamping gap is provided underneath the projection to allow the first clamping finger to be elastically movable. The clamping gap opens out into the receiving pocket and runs from an end face of the holding part that is facing the workpiece to be worked in the longitudinal direction up to the rear end of said holding part, which rear end is arranged in the transitional region between the clamping head and the beam part. A coolant and/or lubricant guide is provided for feeding coolant and/or lubricant to a coolant and/or lubricant outlet arranged in the projection. The projection extends with a continuing portion in the longitudinal direction beyond the rear end of the clamping gap and the coolant and/or lubricant guide runs through the continuing portion.
