Drilling a drill bit for drilling struck comprises a bit head 21 having a greater diameter than that of the drill element that is configured and attached to the end of the drilling element of the drilling assembly. Bit head is provided with a when viewed in the intended drilling direction has a generally frusto-conical shape at the distal end 23 of the frusto-conical phase of the distribution along the extension of the ring for snapping material and fit to be crushed plurality gauge button 25 with substantially it is defined by a circumferential ring (24). Central flush channel (29) has at least one flushing hole (32-35) which opens in the distal end portion to extend through the bit head and guide the flushing medium to the leading end. The at least one flushing hole (32-35) at least one peripheral flushing holes (32-34) of the opening in the distal end portion is opened in a circumferential ring 24 with the substantially. At least two peripheral flushing holes (32-34) are open at the circumferential ring 24 with the substantially.
