A power tool is a tool that is actuated by an additional power source and mechanism other than the solely manual labour 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, or even natural power sources like wind or moving water. Tools directly driven by animal power are not generally considered power tools.
Power tools are used in industry, in construction, in the garden, for housework tasks such as cooking, cleaning, and around the house for purposes of driving (fasteners), drilling, cutting, shaping, sanding, grinding, routing, polishing, painting, heating and more.

Hammer drill

A hammer drill, also known as a "rotary hammer", "roto-drill" or "hammering drill", (see also rotary drill) is a rotary drill with a hammering action.
It is also the act of one person holding a regular drill while the other person "smacks" the back of the drill with a mallet, or light metal hammer.
The hammering action provides a short, rapid hammer thrust to pulverize relatively brittle material and provide quicker drilling with less effort.
These tools are usually electrically powered, and increasingly powered by batteries.
The same technology is also used in electric "demolition hammers", also known as "chipping guns" or "breakers".

Grinding Machine

A grinding machine, often shortened to grinder, is any of various power tools or machine tools used for grinding, which is a type of machining using an abrasive wheel as the cutting tool. Each grain of abrasive on the wheel's surface cuts a small chip from the workpiece via shear deformation. Grinding is used to finish workpieces that must show high surface quality (e.g., low surface roughness) and high accuracy of shape and dimension.

Jigsaw

A jigsaw power tool is a jigsaw made up of an electric motor and a reciprocating saw blade.
A jigsaw with a bevel function on the sole plate allows cutting angles of typically up to 45 degrees relative to the normal vertical stroke for cutting miter joints.
In the past, what are now usually called scroll saws were often referred to as jigsaws.
A power jigsaw may also be referred to, by some manufacturers, as a "bayonet saw" or sabre saw
