The main motions present in a drill are rotation and translation. Rotation refers to the spinning or turning motion of the drill bit, while translation refers to the linear movement of the drill as it drills into a surface or material. Additionally, there may be vibrations present in the drill due to the high-speed rotations, which can impact the stability and control of the tool.
