Abstract (en)
[origin: EP0103283A2] The inventive apparatus comprises a hollow implement for selectively gripping and rotating a tool carrier tube (T) penetrating into said hollow implement, said implement including: a) an actuating head (1) for maintaining the tool carrier tube (T) in rotation; b) a vice (2) made integral with said rotating hollow means, which vice is operated by a not rotating hollow jack (50) arranged concentrically to said rotating hollow means, which jack is suitable to receive therein said tool carrier tube. Preferably, the jack (50) has an axially secured hollow piston (29), while the jacket thereof (38) is movable and controls the radial displacement of the tube gripping jaws (33) through inclined planes or surfaces (27a, 33a).
