How to Operate a Power Drill
Power drills are used for many different tasks, from hanging pictures in your home to heavy-duty construction projects like structural framing. The level of power classifies power drills: a drill may be used for light work, medium work or heavy-duty work. A good all-around drill will have several speeds and allow you to use an array of drill bits. Like any power tool, when operating a power drill, safety should always come first.
