Counterbore tool and setting tool for fascia system and installation method

A drilling tool comprising:

• a working piece comprising a distal shank defining a central axis and a proximal cutting section;
• a collar having a bottom wall defining an inner surface and outer building member abutment surface;
• a retainer mounted relative to the working piece in a rotationally fixed relationship and defining a bottom surface facing the inner surface of the collar bottom wall, the retainer being received by the collar positioned in a rotationally independent relationship;
• and
• an engagement protrusion extending integrally from the retainer or extending integrally from the collar, wherein
• the engagement protrusion forms a contact interface between the retainer and collar, thereby maintaining the retainer and collar in a quasi-floating configuration whereby the working piece and retainer are rotatable relative to the collar with the outer surface of the bottom wall forming an axial stop against a building member.

A drilling tool comprising:

• a working piece comprising a distal shank defining a central axis and a cutting section with a proximal tip;
• a retainer extending from the working piece intermediate the shank and the tip, the retainer and working piece being rotationally fixed, the retainer defining a bottom surface;
• a collar mounted to the retainer in an axially fixed relationship and having an inner surface facing the bottom surface of the retainer,
• an engagement protrusion comprising a continuous annular ring positioned axially between the bottom surface of the retainer and the inner surface of the collar and radially outward of the shank, wherein
• the working piece and retainer are rotatable relative to the collar with the protrusion maintaining axial spacing between the bottom surface of the retainer and the inner surface of the collar.
