Abstract
The hollow core drill has at its lower end, supports which hold diamond-studded cutter plates. These are all set with a front angle of identical, negative value and with a guide angle which varies with the distance from the drill's angle of rotation. The distance from the axis of rotation to the inner edge of the cutting plate furthest from the axis of rotation is less than the distance from the axis of rotation to the outer edge of at least one of the cutting plates nearer to the axis of rotation.
