Abstract
The drill bit comprises a main body, a front face, and an outer surface extending rearwards from the front face. A flush channel (11) extends through the main body to the front face and open ends of the flush channel at the front face are arranged to provide a fluid to an area at the front face, a number of contact points on the front face engaging the area. A flush groove extends from the open end of the flush channel outwards to the outer surface and relief bores (25) extend from the front face rearwards to a relief area behind the outer surface for providing a release for the fluid from the front face to the relief area. The relief bore is located within the flush channel between the open end and the outer surface such that the debris is flushed from the drilling area to an area behind the main body.
