Abstract
The drill has an eccentric center point (1) provided at an end of the drill, where the point includes an active abrasive edge even in a rotation phase in which the drill is rotated around an axis passing via the point. Abrasive teeth (2) are provided in peripheral working areas of the drill. The teeth are arranged on entire width of the end of the drill. The abrasive teeth are arranged in quincunx manner during rotation around the axis of the drill.
