<p>A guide accessory for hand-held electric drills having straight sides. A drill is set up for use simply by inserting it into the guide, where it fits snugly and slides linearly. An enlarged foot section (6) holds the guide perpendicular to the work surface. The foot is abbreviated on one side (8), permitting the guide to be used close to obstacles. An adjustable stop (9, 10, and 11) facilitates drilling holes to precise depths. The stop assembly is also used to tilt the guide for drilling holes at various indicated angles. A stepped "v" block (20) at the bottom of the guide facilitates drilling centered holes in round stock, corners, and the edges of boards. A resilient, transparent material is used in construction to permit viewing the drilling process while protecting the user's hands and eyes. Holes (22 and 23) are provided for ventilating the drill and for hanging the guide on a workshop pegboard.</p> |
