Abstract
A drilling tool has a working piece retained by a retainer mounted to a collar. The working piece includes a distal shank and a cutting section and is rotationally fixed relative to the retainer. The retainer may include an engagement protrusion positioned outward of the shank with the protrusion engaging an inner surface of the collar or the collar may include an engagement protrusion with the protrusion engaging an inner surface of the retainer to create a quasi-floating relationship between the retainer and collar. The cutting section may have a distal primary bore cutting sub-section and a proximal counterbore cutting sub-section. The collar includes a lower surface for abutment against a building member during drilling operation to halt axial movement of the tool.
