Abstract The object of this investigation was to determine the amount of heat which goes into the workpiece, chips, and drill at different cutting speeds and feeds. A tubular test bar of extruded Dowmetal was used as the workpiece, thus making the cutting action of the drill similar to that of a single-point tool. The total heat, the heat in the chips, and the heat in the drill were measured separately in a calorimeter.
