Abstract

An electric power tool (100) includes a power source (102) enclosed in a casing (104). The power source (102) is a brushless DC motor (202) which drives a drive mechanism (106) for a cutting device. Further, an oil pump is at least partly housed in the casing (104) of the electric power tool (100). The oil pump is also driven by the brushless DC motor (202).
