Abstract

The invention relates to a drill, especially a Forstner bit or a multi-spur machine bit, having a drill shaft (2) and a cutter head (4) which is provided with a central mandrel (1). A first and a second spur cutter (100, 100') radially extend towards the outside from said mandrel and in opposite tool approach directions. A hollow cylinder segment-like wall (10) respectively that has a circumference cutter (8) and defines the circumference of the cutter head (4) is joined to the ends of the first and second spur cutter (100, 100'), whereby said ends face the circumference. Said wall defines a chip space (7) on the end thereof that faces away from the spur cutter (100, 100'). Said space opens to the respective remaining spur cutter and penetrates the drill head. The two circumference cutters (8) are provided with wave-shaped cavities (13) and elevations (14), at least partially along the side thereof.
