Abstract

A descending bore tool 10 for inserting in a drill rod 11 includes elongate semicylindrical sleeve tool sections 18, 20 intended to be supported in a non-rotary manner on an elongate cylindrical body 12. The tool sections 18, 20 can be mounted on and removed from the body 12 without disconnecting any end of the tool 10 from the drill rod 11. The half-bushing tool sections 18, 20 are provided with conical flanges 30, 36 which extend axially at their opposite ends, which fit in corresponding conical recesses 32; 62, 16 formed on the body 12 of the tool and the tool sections 18, 20 are retained on the body 10 by a nut 52 applied by means of threading with the body 12 and applicable with an axially movable retention collar 50. The tool sections 18, 20 may be applied drivably with axial keys 44 formed in the body 12 or the tool sections 94, 96 may be formed with planar surfaces 136 on the inner sides of the sleeve interacting with complementary planar surfaces 84 formed on a portion 82 of reduced diameter of the body 72 around which the tool sections 94, 96 are mounted.
