Abstract
A double or multiple-edged drilling tool has a base body rotatable about a drilling axis, and at least two plate seats arranged on the front face for accommodating identical interchangeable cutting plates. The cutting plates each have a machining face, and a clearance face adjoining a principal cutting edge forming a cutting wedge, and a seat face facing away from the clearance face. A guiding land adjoins radially outwardly through each edge the machining face, the clearance face and optically the seat face. The cutting plates each have a hole for a retaining screw which is screwed into a threaded bore at the front face of the base body. The holes are aligned with their axis perpendicular to the clearance face of the associated cutting plates the threaded bores are aligned inclined to the drilling axis and inclined to each other in the base body.
