Description:

This lathe attachment is intended for stamping characters or logos on a workpiece. The attachment mounts in the tool holder and is pressed forward into the rotating workpiece. The periphery of the disc, which has raised letters that are to be embossed into the workpiece, is to be the same circumference as that portion of the workpiece it engages with and the disc rotates in synchrony with the workpiece such that the letters of the disc are cleanly embossed into the workpiece.
