Abstract
In drilling operation, selection of type of drill bit and its material are very important for the procedure. In the present work, the considered twist drill bit made up of different materials and having different parameters such as helix angle, point angle, and diameter and performing simulation on all of the drill bit. Modelling of drill bit is done on SOLIDWORKS 2019, and the analysis is being performed on the ANSYS workbench 2021 R1. AISI Type M2 molybdenum high-speed tool steel which is most commonly used for manufacturing drill bits is compared with tungsten carbide drills, HSS drill bit, and SS drill bit. This research concludes that by increasing the helix angle, there is an increase in stress formation and decrease in deformation; while increasing the point angle, the stress formation on drill bit increases, but it starts to decrease after 120° and there is an increase in deformation.
