A hand drill is a drill which is held in the hand. Some people reserve the term “hand drill” specifically for drills which are operated by hand, distinguishing between hand-held power drills and drills which are powered by their users. Many hardware stores sell hand drills, along with bits which can be used for various drilling projects, and a hand drill can be a very useful tool to keep around the house, shop, or car.

In the case of a literal hand drill operated by hand, the drill has a circular crank which the user turns to operate the drill. The circular motion of the crank drives the drill bit, causing it to drill a hole. This type of hand drill can be used in a range of applications, some of which are more esoteric than others. For example, a hand drill can be used to start a fire when other tools are not available, with the drill being utilized to create friction, which causes heat and the eventual outbreak of flames.

Traditional hand-powered drills require little in the way of maintenance. It is usually necessary to periodically wipe down and oil the drill so that all of the parts move smoothly, and occasional oiling may be needed to prevent rust. Various components of the drill such as wooden handles or the screws which hold the bit in place may also need to be replaced now and then as a result of wear.

In terms of hand-held power drills, there are a range of options which can be divided between corded and cordless drills. These drills can be fitted with a range of bits which can drill holes, drive screws, mix paint, and stand in for a variety of other tools. The performance of such drills varies, depending on the amount of power they have, and how well maintained and constructed they are.

An electric hand drill generally requires more careful maintenance, because the drill has more parts. If the drill is corded, the cord must be kept in good working order to prevent fraying and the risk of shock. The drill must be periodically broken down for cleaning and oiling to keep it running smoothly, and it may be necessary to inspect the wiring and circuits in the drill to confirm that it is in good working order. If the drill is powered by batteries, it will also be necessary to care for the batteries properly to ensure that they have a long and productive life.
