The mechanical and physical properties of both ferrous and non-ferrous alloys may be improved using a heat treatment process called cryogenic heat therapy, which has been used for centuries. It is cost-effective to use cryogenic treatment on cutting tools because it improves their hardness, wear resistance, and dimensional stability while decreasing tool consumption and minimizing downtime during machine tool setup. Understanding the characteristics of these tool materials is crucial because of the impact they have on the turning process. Modifying and bettering these tool steels' characteristics will make machining more efficient. In this paper the lifespan of cryogenically treated tools to those that were not treated were compared by conducting an experiment using conventional lathe machine by doing turning operation. Cryogenically treated and untreated HSS tool bits were used to perform a turning operation on a hardened steel bar at varying speeds (90, 140, 230, 310, 500, and 725 revolutions per minute), and graphs were drawn to compare the tool wear and time interval for each speed. Cryogenic treatment on an HSS cutting tool affects its ability to machine a variety of tool materials with improved surface polish and extended tool life. The results showed that the cryogenically treated tool had lasted longer than the untreated tool at all speeds.
