摘要：
Provided herein is a drill for a dental implant. The drill for a dental implant includes a coupling part connected to a hand piece configured to provide a rotational force, a body part disposed below the coupling part and configured to transmit the rotational force downward, a cutting part including a plurality of cutting blades and a void section, the cutting blades being disposed below the body part in order to cut an alveolar bone and form a hole therein and being spaced apart at a predetermined angle in a rotational direction, and the void section being surrounded by the cutting blades along at least a portion of an inner circumference of the cutting blades, and a coolant passage configured to communicate with the void section by passing through the coupling part and the body part and configured to, while the alveolar bone is being cut, supply coolant to the void section so that the coolant is introduced to the cutting blades.
