A New Surgical Drill Bit Concept for Bone Drilling Operations

During surgical interventions, bone tissue may be damaged by the achieved high cutting efforts and thermal damage, which should be avoided. In this study, a new surgical drill bit with two types of cutting edges is proposed and tested, reducing tissue damage. Large part of the material is removed by brittle crack propagation, and surface is finished precisely with small uncut chip thickness. Even if temperatures achieved in the bone are not reduced due to rubbing effects, lower cutting force and processing energy, and better surface roughness are obtained with the proposed tool compared to the conventional drill bit.
