Sockets, of the type enabling the drill point to be set central, have a spherical portion held on its seating by a cap and ring D floating on compression springs. Driving - claws A<4> with rounded edges engage claws on the spindle end or adaptor. A transverse cotter A<6> is employed for securing boring-bars. In a modification, the spherical surface is formed at the head of the socket, and in a further modification it is constituted by a separable ball.
