A drill is an extremely useful tool that, when using the appropriate bit, can be used to drill holes into wood, metal, concrete and a host of other materials and surfaces. A battery drill relies on a battery pack, usually attached at the bottom of the drill, to provide the power source. Battery packs come in various sizes and shapes and with proper care can last for a number of years.
Though useful, a corded power drill has its shortcomings, especially when working outside because long extension cords are required to tie the drill into an electrical receptacle. With the advent of the battery drill, tradesmen and weekend hobbyists alike have found working with drills less restrictive. A battery drill, also known as a cordless drill, allows workers the opportunity to move freely about a work site without having to drag extension cords behind them. Battery drills are also available in heavy-duty sizes (hammer drills) which will allow the operator to perform difficult drill jobs that a smaller battery drill would not be powerful enough to perform.
New battery drills usually come with two battery packs. Accordingly, while one battery is being used to power the drill, the remaining battery can be plugged into a charger to ensure it is fully charged and ready for use. Cordless drill batteries are offered in various voltages typically ranging from 12 to 24 volts. The higher voltage drills usually have more power, but they also cost more. The use of battery powered tools of all kinds are now favored by tradesmen. On a typical jobsite, you can find battery powered drills, circular saws, screwdrivers, jig saws, and reciprocal saws, to name a few.
Drywall installers belong to a group of construction workers who usually prefer battery drills over plug-in models. Drywallers can set the speed control of the drill to allow it to drive screws into and secure drywall products to either wooden or metal studs in new construction projects.
Cordless drills can be used with a wide variety of drill bits that vary from the most common, or twist bits, to forstner bits and hole saws.
Some of the most popular manufacturers of battery drills include Makita, DeWalt, Bosch, Hilti, and Craftsman; they all offer drills that fit the needs of the weekend warrior and trades professionals alike.
