A quick stop device for abruptly interrupting the cutting of a workpiece by a cutter is disclosed. The quick stop device employs an outer housing connected to an inner workpiece holder by at least one shear pin. The outer housing includes an appropriate shank designed to be received in the spindle of a machine, such as a machine tool. A cutter, such as a drill bit, is mounted in a stationary position and the workpiece, mounted to the workpiece holder, is rotated during engagement with the cutter. A trigger system includes at least one spring loaded punch disposed for movement into engagement with the workpiece holder to abruptly stop rotation of the workpiece holder. This action shears the shear pin and permits continued rotation of the spindle and outer housing without substantially disturbing the chip root formed during cutting.
