Abstract

Tool holder assemblies (1) comprising a tool receiving portion R and tool gripping means (12, 13b) for gripping a tool received in the tool receiving portion, the tool gripping means comprising at least one tool gripping portion (13b) which is moveable between a tool gripping position and a tool release position, and a memory metal portion (12) which is controllably transformable in response to change in temperature between a first shape and a second shape and is arranged to act upon the tool gripping portion to move the gripping portion towards the tool gripping position as the memory metal portion transforms from the first shape towards the second shape.
