Abstract

The present invention relates to a fluid-operated percussion drill tool (1) comprising an outer wear sleeve (2) comprising a substantially cylindrical wall (3) and having inner (4) and outer (5) surfaces. The tool also comprises a percussion bit (6) having a head 5 portion (7) and a bit retaining portion (8) and located at a forward end (9) of the outer wear sleeve. The tool further comprises a sliding piston (10) mounted for reciprocating movement within the outer wear sleeve to strike the percussion bit. The tool also includes a drive ring (11) having a substantially cylindrical wall (12) and comprising connection means (13) adapted for connecting the drive ring to a drive means of the 10 fluid-operated percussion drill tool. At least one flushing channel (31) provides a fluid path to the cutting face of the bit for a flushing medium. A first portion (32) of the at least one flushing channel extends longitudinally within the wall (3) of the wear sleeve, a second portion (36) of the at least one flushing channel extends longitudinally within the wall (12) of the drive ring and a third portion (40) of the at least one flushing 15 channel extends through the head portion (7) of the percussion bit to the cutting face (43) of the bit. <Figure 1>
