Touch probe including a fixed part ( 250 ), designed to be fastened onto a measuring machine or a machine tool, and a contact feeler ( 30 ) that is mobile and orientable on two independent axes ( 211, 212 ) along a multiplicity of directions indexed in space. An actuator ( 300 ) comprising antifriction rollers and a ball bearing allows the rotation axes ( 211 ) to be unlocked and any orientation to be selected with minimized friction. In locked position, the actuator ( 300 ) withdraws under the action of return springs ( 336 ) so as not to influence the indexing accuracy.
