Abstract
A tool shank (18;38;138) is described that comprises a spindle attachment portion (20) that is removably attachable to the rotatable spindle (12) of a machine tool (10), a shank body portion (21;121) which extends beyond the end of the spindle when the tool shank (18;38;138) is attached to the spindle (12) of a machine tool (10) and the first part (26;38;148) of a separable electrical coupling (22;132). The shank body portion comprises a feature (28;128) suitable for engagement with a tool change device (29) and the first part (26;38;148) of the separable electrical coupling (22;132) is located on the shank body portion (21;121) between the feature (28;128) and the spindle attachment portion (20). A machine tool (10), and a kit for retrofitting a machine tool (10), that comprise the second part (24;148) of the separable electrical coupling (22;132) are also described.
