Abstract
A drill crown with rotary cutters has a body that comprises a tail element and a head at the end of which the cutters with diamond-hard-alloy plates are installed. To increase stability of the drill crowns, the axes of the cutters are arranged at angles with respect to the axis of the crown that provide rotation of peripheral cutters due to friction of the back surfaces of those by the walls of the well, and for the cutters placed more closely to the axis of the crown, due to friction of the back surfaces of those by the lug formed near the axis of the well. That for the axes of the cutters are inclined to the side opposite to direction of translational motion at angles from 20 to 25 degrees in planes arranged at angle 45 degrees with respect to the lines that go through the axes of the cutters at different edges of those.
