Drill Machines: A drill is a tool primarily used for making round holes or driving fasteners. It is fitted with a bit, either a drill or driver, depending on application, secured by a chuck. Some powered drills also include a hammer function.

Drills vary widely in speed, power, and size. They are characteristically corded electrically driven devices, with hand operated types dramatically decreasing in popularity and cordless battery powered ones proliferating. Drills are commonly used in woodworking, metalworking, machine tool fabrication, construction and utility projects. Specially designed versions are made for medicine, space, and miniature applications.

Power Tools: ​A power tool is a tool that is actuated by an additional power source and mechanism other than the solely manual labor used with hand tools. The most common types of power tools use electric motors. Internal combustion engines and compressed air are also commonly used. Other power sources include steam engines, direct burning of fuels and propellants, such as in powder-actuated tools, or even natural power sources such as wind or moving water. Tools directly driven by animal power are not generally considered power tools.
