Abstract

An integral tool bit for drilling a rock formation, including a cemented metal carbide holder (30) attached to the tool and joined, e.g. soldered, to a plate (34) in the form of a cylindrical disc made from polycrystalline diamond particles and having a side wall (40) and a substantially flat free surface (36), said plate (34) being positioned so that the plane of its free flat surface (36) is at an acute angle (.alpha.) to the line (N) normal to the surface (25) of the rock formation, and said angle being directed in the same direction as the forward direction (F) of the drill bit so that the plate engages the rock formation with its side wall (40).
