Rock drill in particular for hammer-drilling machines, with a drilling head formed from a circular cylindrical drill head (2) to which end face a radially extending, the entire drilling head (2) which passes through main cutting tip (3) is arranged, which the peripheral contour (9) of the drill head (2) projects radially beyond, wherein a first vertical longitudinal plane of symmetry (18) longitudinally through the main cutting tip (3) and a second longitudinal plane of symmetry (17) at right angles for this purpose through the drill longitudinal axis (19) and in addition to cutting elements (7, 8) which, when compared with the drill along symmetry planes (17, 18) eccentrically and / or at an angle for this purpose are arranged, and wherein the drilling head (2) than four cutter (4, 5, 7, 8) is formed, characterized in that the secondary cutting tips (7, 8) with respect to the main cutting tip (3) transversely, but not radially and eccentrically with respect to the drill along symmetry planes (17, 18) are arranged, whereby diametrically opposite secondary cutting tips (7, 8) in their geometric arrangement with respect to the vertical longitudinal plane of symmetry (18) by means of the main cutting tip (3) not parallel to it and eccentrically off-center are arranged symmetrically or asymmetrically.
