A power tool is run by an electric motor, a compressed air motor, or a gasoline engine. Power tools are classified in two categories: stationary or handheld (portable). Power tools are used in industry and around the house.
Known to ancient Egyptians, the oldest power tool is the lathe. Early industrial revolution factories had power drills driven by belts from overhead shafts. The invention of the electric motor in the 1880s made possible self-powered stationary and portable drills that we use today.
Portable power drills may be either corded or battery powered. The lower price and limited battery life has keep corded power drills on the market. However, companies have discovered that by including two or more rechargeable batteries as part of the set and making lighter weight drills, consumers are moving rapidly toward the cordless power drill.
While the trigger type switch and pistol-grip handle is still the most popular power drill design, there are a variety of hand grip styles to choose from in 1/2 inch, 3/4 inch, 3/8 inch power drills to make your woodworking projects easier. Power drills are now on the market to fit smaller hands as well. Browse eBay to find a drill that suits your needs.
