Guide device for a cutting tool

A guide device comprising:

• a first end section comprising:
• an exterior surface;
• an interior surface defining an opening extending through the first end section along a central axis, the opening being sized and shaped to receive a drill bit therethrough;
• and
• a drill bit securing aperture extending between the interior surface and the exterior surface perpendicular to the central axis, the drill bit securing aperture being sized and shaped to receive a mechanical fastener for securing the first end section to the drill bit;
• a second end section comprising a hollow body having an opening extending therethrough along the central axis, the opening being sized and shaped to receive the drill bit therethrough, the second end further comprising a plurality of apertures extending perpendicular to the central axis, the plurality of apertures distributed radially about the second end section to accommodate the passage of debris therethrough;
• and
• an intermediate section comprising:
• a hollow body having a first outer diameter, wherein a first end of the hollow body comprises external screw threading;
• and
• a collar section disposed at a second end of the hollow body opposite the first end, the collar section having a second outer diameter larger than the first outer diameter;
• wherein the second end section is slidably and rotatably coupled to the first end section such that the second end section can remain stationary relative to a substrate being drilled while the first end section is rotated by a rotating drill bit secured thereto;
• and
• wherein at least a portion of the interior surface of the first end section of the guide device comprises internal screw threading, such that the second end section is rotatably and slidably securable to the first end section by inserting the intermediate section through the opening of the second end and engaging the external screw threading with the internal screw threading.
