A drill is a tool with a rotating drill bit used for drilling holes in various materials. Drills are commonly used in woodworking and metalworking.

The drill bit is gripped by a chuck at one end of the drill, and is pressed against the target material and rotated. The tip of the drill bit does the work of cutting into the target material, slicing off thin shavings (twist drills or auger bits) or grinding off small particles (oil drilling).

History

The earliest drills were probably bow drills. The invention of the electrical drill is credited to both Arthur James Arnot [1], in 1889, at Melbourne, Australia and Wilhelm Fein [2], in 1895, at Stuttgart, Germany. In 1917, Black & Decker patented a trigger-like switch mounted on the handle.

Types

There are many types of drills; some powered by hand and others using electricity or compressed air as the motive power. Drills with a percussive action (such as hammer drills, jackhammers or pneumatic drills) are usually used in hard materials such as masonry or rock.

An oil well, water well, or holes for geothermal heating are created with large drill rigs up to a hundred feet high. Some types of hand-held drills are also used to drive screws.
