摘要： Disclosed is a machine tool collet having a collet body having a shaft for receiving a cutting tool at a forward open end thereof and a rearward open end insertable into a tool holder means, at least one first axial slit opening into the rearward open end of the shaft and at least one second axial slit opening into the forward open end of the shaft, and a transverse channel connecting the first and second axial slits to thereby provide a pathway for the flow of a fluid from the rearward open end of the shaft to the forward open end of the shaft to thereby enable the fluid to move from the cutting tool machine through the collet to the workpiece during the cutting operation.
