9 . A method of forming a surgical drill bit, the method including:
selecting a first guide body component from a plurality of guide body components, wherein the first guide body component has a guide body with at least one of a length and a width that is different from at least one other guide body of other guide body components of the plurality of guide body components and wherein the first guide body component further includes a guide body portion including a guide body and an engagement portion coupled to the guide body portion;
selecting a first drill body component from a plurality of drill body components, wherein the first drill body component has a drill portion that is different from at least one other drill portion of other drill body components of the plurality of drill body components, and wherein the first drill body component comprises a latch that extends from a stop surface that is provided in an orthogonal orientation relative to a shaft of the first drill body component; and
reversibly coupling the first drill body component to the first guide body component, wherein the first guide body component reversibly couples to the first drill body component with:
a cylindrical chamber having an outer diameter and an inner diameter;
at least one flexible finger having a first end fixedly connected to the shaft and a second end that flexes outwardly from a central axis of the first guide body component within the cylindrical chamber to receive the first drill body component and then flexes inwardly toward the central axis of the first guide body component to longitudinally retain the first drill body component within the cylindrical chamber by mating with the latch, wherein the first end is fixedly connected to the shaft and extends substantially parallel with the central axis to the second end; and
a flat that mates with a corresponding flat of the first drill body component, wherein the flat is contained within the inner diameter of the cylindrical chamber, and wherein the flat of the first drill body component is provided as part of the latch.
10 . The method of claim 9 , wherein the first drill body component includes the drill portion, wherein the shaft is positioned between the drill portion and an engagement end that include the latch, and wherein the engagement portion includes a tool end and a connection end, wherein the connection end is configured to couple with the guide body portion and reversibly couple with the engagement end of the first drill body component.
11 . The method of claim 10 , wherein reversibly coupling the first drill body component to the first guide body component, includes:
inserting the engagement end of the first drill body component into the cylindrical chamber until the engagement end couples with the latch of the engagement portion of the first guide body component.
12 . The method of claim 9 , wherein, when the first drill body component is coupled to the first guide body component, a portion of the at least one flexible finger is positioned within a groove provided along the latch.
13 . The method of claim 12 , wherein the at least one flexible finger comprises a pair of flexible fingers, both of which flex outwardly from the central axis of the first guide body component to receive the first drill body component and then flex inwardly toward the central axis of the first guide body component to retain the first drill body component via engagement with the latch.
14 . The method of claim 13 , wherein the at least one flexible finger comprises a tapered surface that defines a shoulder to mate with the latch.
15 . The method of claim 9 , further including:
decoupling the first drill body component from the first guide body component by applying a longitudinal force substantially parallel with the central axis of the first guide body component to disengage an engagement end of the first drill body component from the first guide body component.
16 . The method of claim 9 , further including:
selecting one of a second guide body component to couple with the first drill body component and a second drill body component to couple with the first guide body component,
wherein the second guide body component has at least one of a length and a width that is different from at least one of the length and the width of the first guide body component, and wherein the second drill body component has drill portion that is different from the drill portion of the first drill body component.
17 . A dental surgical system, comprising:
