The response characteristics of a drill bit (i.e., the damped characteristics) can be under, critical, or overdamped given its motion equation, that is, (1).
This study defined equations for the motion of a drill bit when struck by a piston and expanded the dynamic properties of the drill bit based on the conditions [zeta] and [alpha].
This paper proposed six conditions for the dynamics of a drill bit struck by a piston impact, as summarized below.
The tendency of a drill bit to drill over size is known as runout, and can be minimized by step drilling to within about 1/64" (.015") of full size, then using the full-sized bit to finish the hole.
