In the present work, coated tungsten carbide tool tips of ISO P-40, were subjected to normal cryogenic treatment (−110°C). Machining studies were conducted on C45 workpiece using both untreated and cryogenic treated tungsten carbide cutting tool inserts in a high precision CNC lathe. The machining performance is evaluated in terms of flank wear of the cutting tool inserts, main cutting force and surface finish of the machined workpieces. The flank wear of cryogenic treated carbide tools is lower than that of untreated carbide tools on machining of C45 steel. The cutting forces during machining of C45 steel is lower with the cryogenic treated carbide tools when compared with the untreated carbide tools. The surface finish produced on machining the C45 steel workpiece is better with the cryogenic treated carbide tools than when compared with the untreated carbide tools.
