Alignment device for aligning a drill bit with a pilot hole

A system for aligning a drill bit with respect to a pilot hole, the system comprising:

• a drill assembly comprising:
• the drill bit;
• and
• a motor being configured to rotate the drill bit;
• and
• an alignment device configured to be positioned in abutment with the drill bit of the drill assembly, the alignment device comprising:
• a base having a first surface and a second surface, wherein the first surface is opposite the second surface;
• an alignment pin extending from the first surface of the base, wherein the alignment pin is solid such that it does not include a through-hole;
• and
• a support extending from the second surface of the base, wherein the support is positioned such that a longitudinal axis of the alignment pin is separated from an inner surface of the support by an offset distance, wherein the inner surface of the support has a radius of curvature along a length of the support, wherein the radius of curvature is substantially equal to the offset distance, wherein a center of curvature of the support is coaxial with the longitudinal axis of the alignment pin, and wherein the inner surface of the support comprises an arc of a circle such that there is a gap along the length of the support.

A method for aligning a drill assembly with respect to a pilot hole, the method comprising:

• positioning a drill bit of the drill assembly in abutment with an alignment device, wherein the alignment device comprises (i) a base having a first surface and a second surface, wherein the first surface is opposite the second surface, (ii) an alignment pin extending from the first surface of the base, wherein the alignment pin is solid such that it does not include a through-hole, and (iii) a support extending from the second surface of the base, wherein the support is positioned such that a longitudinal axis of the alignment pin is separated from an inner surface of the support by an offset distance, wherein the inner surface of the support has a radius of curvature along a length of the support, wherein the radius of curvature is substantially equal to the offset distance, wherein a center of curvature of the support is coaxial with the longitudinal axis of the alignment pin, and wherein the inner surface of the support comprises an arc of a circle such that there is a gap along the length of the support;
• positioning the alignment pin into the pilot hole on a surface such that the longitudinal axis of the alignment pin is coaxial with a center of the pilot hole;
• and
• fixing a position of the drill assembly with respect to the surface.
