C. & E. Fein GmbH is a manufacturer of high-end power tools located near Stuttgart, Germany.

Fein's fire alarm systems were widely adopted in cities including Nuremberg (1878), Gotha (1881), Ludwigsburg (1881), Frankfurt (Oder) (1882), Worms (1883), Regensburg (1887), Eßlingen am Neckar (1891), Bayreuth (1891), Karlsruhe (1892), Schwerin (1894), and Kempten (1984).

In 1895, Fein invented the electric hand drill, which is considered the forerunner of power tools.

The first power tool with oscillation technology was launched in 1967, at the time as a plaster band cast saw.

In 1987, the Fein quick-clamping system QuickIN made the handling of angle grinders considerably safer.
