An improved device for the stamping of identification or other insignia on work pieces as part of the operations performed thereon in rotating machines such as lathes, automatic lathes, screw machines or the like. The stamping device is carried on a tool slide of the machine for movement toward and away from the work piece and includes a stamp having a flat face containing raised characters intended to be imprinted in the work piece, means to move the stamp to an extreme outer position when the slide is withdrawn from the work piece and to latch the stamp in said outer position, and means responsive to contact of the stamp assembly with the rotating work piece as the slide is moved toward the work piece to release the latch means. Spring means accelerate the stamp assembly in a direction such that the first character on the stamp engages the work piece, at which time the work piece drives the stamp past the work with stamp and work surfaces moving together to imprint the characters on the stamp into the work piece surface.
