A tool identification system, comprising: a tool holder (8) allowing removable attachment thereto of any one of a plurality of tools; a sensor (22,11,16) arrangement operable to sense features (22) present on a tool (18) attached to the tool holder (8); a processor (17) operable to identify uniquely, from the sensed features, the type of the tool attached to the tool holder; and an insulation arrangement provided between the tool holder (8) and the sensor arrangement, thereby electrically insulating the tool holder (8) from the sensor arrangement. <IMAGE> |
