Rise in temperature is inevitable in orthopaedic drilling. Massive research had been
done in the field of orthopaedic drilling to investigate the effect of cutting conditions, bone related
parameters, and drill bit geometric parameters on heat generation and minimum surrounding tissues
injury. In present research, contradictory conclusions regarding the cutting conditions and drill bit
geometric parameters were observed. Minimum temperature of 31°C was achieved at speed of 186
rpm, feed of 0.196 mm/rev, drill diameter of 3.85mm, and drill tip angle of 110°. Response Surface
Methodology (RSM) was used to develop a mathematical model to predict the type of relationship
between inputs and response. It was concluded that the most influencing parameter was drill diameter.
