Abstract— Cryogenic treatment is considered as a recognized treatment to improve the wear resistance of HSS tools. Different researchers have explained the exact mechanism behind this improvement. However, the impact of cryogenic treatment on cutting forces and surface finish has not yet considered by the researchers. The purpose of present work is to study the impact of two variables in cryogenic treatment, viz., soaking temperature and soaking period on the performance of drills in terms of cutting torque and surface finish of work piece in drilling operation. The various drills were given different cryogenic treatment and their performance in drilling operation was tested. After rigorous experimentation it was found that the soak temperature and soak period has great impact on the performance of drilling operation in terms of the selected response variables like roughness value, torque, etc. This cryogenic treatment was carried out for a AISI M2 grade of HSS tools only and hence further research is required to be carried out to study such impact on other grades of HSS or other tools. The use of this treatment has got great impact on industrial productivity in terms of improved tool life of drills or other such cutting tools made of same material.
