Abstract

The invention relates to a rock-destroying tool, more specifically to roller drill bits with air drilling ability and can be used for drilling of rocks of high hardness. The drill bit is comprising a body and rock-destroying elements with the equipment mounted on the body one inside the other by means of bearing supports, wherein the one, inwardly assembled, is located at an angle relatively to the axis of the drill bit, and the outer one is located in the opposite direction of the axis of the drill bit. The increase of the service life, high efficiency and commonality are ensured due to the fact that the equipment of the rock-destroying elements is introduced as replaceable jet nozzles made of hardwearing material and provided with cutters made of wolframite-cobalt based alloy, on the top of that the bearing support of each rock-destroying element is furnished with the device to adjust axial play value.
