A knurling tool is used along with a lathe to emboss the ends of metal tubes and shafts. The embossed grooves may act as hand grips for the user or better traction for rubber or plastic covers.
The knurling tool itself consists of multiple rotary cutters which are held against the metal shaft as it turns on the lathe at a relatively slow speed (500 rpm on average). Turning is a method by which cylindrical pieces of metal or wood are spun in place by a variable-speed electric motor. As the piece spins, various cutting tools can be placed against it to remove material or cut shapes.
A knurling tool is best described as a cross between an engraver and an embosser.
