Terminology
The word "jackhammer" is used in North American English and Australia, while "pneumatic drill" is used colloquially elsewhere in the English speaking world, although strictly speaking a "pneumatic drill" refers to a pneumatically driven jackhammer. In Britain, the term "jackhammer" usually refers to electromechanical version of the tool. The name "Kango" is also used in Britain for an electromechanical jackhammer and comes from a former British brand name now owned by Milwaukee tools.
