Abstract: A multi-edge reamer has a cutting region having a main body with a central axis. A first number of first cutters and a second number of second cutters extend from the main body. Each first cutter has a cutting edge and an adjoining circular grinding chamfer which forms a guide region for a corresponding first cutter and has a first width. Each second cutter has a cutting edge and an adjoining circular grinding chamfer which forms a guide region for a corresponding second cutter and has a second width. The first width is greater than the second width, the first number of first cutters is greater than the second number of second cutters, and all of the first cutters directly adjoin one another when seen in the circumferential direction so as to be arranged in a continuous group.

Abstract: The invention relates to a method for determining a working depth of a tool. The method includes arranging a tool and a depth determination device on a depth setting device; and applying a predetermined compression force in axial direction to the depth determination device, such that at least a part of the depth determination device is elastically compressed by a certain compression amount against a contact surface, obtaining a compressed state of the depth determination device. The method further includes securing a mounting device to a clamping region of a shaft of the tool in the compressed state of the depth determination device such that the mounting device is firmly mounted to the clamping region, whereby a tool assembly is formed; releasing the compression force from the depth determination device, and removing the tool assembly from the depth setting device.
