Abstract

The core-cutting drill forms oblique holes, pre-drilled core socket. The top of a tubular round section body (11) is free to rotate in a jacket (17) with hydraulic fluid (24) and coolant (18) feeds, the head (12) coupling to a drive shaft, and the foot locating the cutters (15). The bore locates a sealed piston (101) which can slide axially, and is itself bored to locate a freely rotatable shaft (105). The shaft projects forward to form a punch (119) with a cone top (22) locating an expandable sleeve (123) with a conical bore (127). Initially, the sleeve is placed in the core socket, the punch then descending with the piston (101) to lock the sleeve in the socket in both the axial and radial senses. The tube is now rotated to advance and effect the cut, guided by the piston. Sleeve release is effected by a screw-jack (134) or by a cammed lever.
