    Abstract: A rotary cutting tool is provided for cutting an opening in a sheet of material (e.g., drywall) around a pre-installed item (e.g., an electrical box). The cutting tool may include a shaft, at least one cutter, a guide tip and a shoulder formed by a lower edge of the cutter adjacent the guide tip. The shoulder may have a width that corresponds to the width of a wall of the pre-installed item. The width of the shoulder may be equal to the width of the wall, or it may be slightly greater than the width of the wall. The guide tip may include a bearing to prevent marring of the wall of the item when the guide tip is rotating and in contact with the wall. An adjustable collar and corresponding bearing may also be disposed around the shaft for controlling a preferred cutting depth of the cutter. The cutting tool may be engaged with any suitable rotary tool, including one having an adjustable table for controlling a preferred cutting depth of the cutter. Related methods of using a cutting tool to cut an opening for receiving the item or box are also provided. The rotating guide tip may be moved into contact with the wall and the shoulder may be positioned above and/or in contact with an upper edge of the wall. The cutting tool is then moved around the wall while rotating to cut an opening in the material through which the item or box may be positioned.

    Abstract: A system, method, and apparatus for the rigid alignment of drill bits with ergonomic drill motors is disclosed. An adjustable nosepiece adapter is mounted to the ergonomic drill motor adjacent the drill bit chuck. The adapter has a split clamp portion on its distal end for receiving a pressure foot. A guide bushing fits in the proximal end of the pressure foot. A coil spring is located in the pressure foot and allows the guide bushing to telescope within the pressure foot. The drill bit extends through the guide bushing, pressure foot, and adapter and is secured to the chuck. The distal end of the guide bushing fits closely within a hole in a template that is secured to the workpiece to provide holes that are more accurately formed in the workpiece.

    Abstract: A hand drill guide comprising an annular base and a plurality of telescopic leg assemblies distributed along the base. Each assembly has a hollow cylinder, fixed perpendicularly at one end to the base, and a rod slidably mounted in the cylinder, the rod extending out of the cylinder through an opening. The drill guide also comprises an annular positioning head to which the other ends of the rods are fixed, and an annular drill holding assembly mounted for selective location on the cylinders. The rod has a retaining ring rigidly connected thereto at a given distance from its upper end to prevent the rod from escaping from the cylinder. A ring is floatingly mounted on the upper portion of the rod inside the cylinder and two springs act on the floating ring: one between it and the upper end of the cylinder and the other between it and the retaining ring, both springs being uncompressed when the retaining ring is adjacent to the bottom end of the cylinder. A stiffening annular member preferably interconnect the cylinders at their open ends. In addition, the positioning head is preferably provided with a manually operable finger which can be moved to show where the center of the drill guide is located, that is where the hole is to be drilled.

    Abstract: The improved dwell and depth attachment includes an elongate housing that is attached to a drill motor and has an output shaft that is movable longitudinally and rotatably in the housing for rotating a drill bit. A drive spindle is connected with the output shaft and extends through the housing. An elongated sleeve encircles the spindle and has an end that is engageable with the work piece. An adjustable depth control located within the housing is connected for movement with the spindle. A first portion of the control includes a threaded interior and has ten circumferentially spaced, radially extending holes therein. The control also includes a second portion that has a threaded exterior mating with the first portion and has ten slots equally spaced about the exterior. A stop screw or the like is removably located in one of the radial extending holes in engagement with the second portion. The holes and slots are arranged so that rotation of the second portion relative to the first portion by one slot changes the drilling depth by one-tenth of the screw amount caused by full rotation. Further, movement of the stop screw from one hole to the next changes the drilling depth by one-hundredth of the amount caused by one full rotation.
