Abstract: Fluid driven down-the-hole drilling machine. The hammer piston (2) of the down-the-hole drilling machine is adjacent to its front end provided with a cylindrical part (6). The drill bit (3) is provided with a first impact surface (41) which receives impacts during drilling, a second impact surface (42) and an annular section (7) which surrounds the cylindrical part (6) between the impact surfaces. The second impact surface (42) receives the impact energy of the hammer piston at reversed feeding of the housing (1) of the down-the-hole drilling machine for freeing the drill bit when it has become stuck.
