摘要

Reamer (35), comprising - a base (36) body, - a rotation axis (43), - at least one seat for the insert (39) countersunk in the base body (36) including at least a first and a second side surface (47, 49), - a cutting insert (1) inserted in the seat for the insert (39) including at least one secondary cutting edge (31A, 31B, 31C, 31D), in particular, one cutting insert as set forth in claims 10 to 14, - a clamping device (55) comprising a clamping jaw (57) holding the cutting insert in the seat for the insert where the cutting insert ( 1) can contact at least the second side surface (49) of the seat for the insert (39) under the action of the clamping jaw (57), and comprising - an adjusting device (63) including a adjusting piece (69) by which the projection of at least one cutting edge of the cutting insert (1) is adjustable on a superfic ie circumferential (40) or on at least one guide strip (73A to 73E) of the reamer (35), characterized in that - at least the first side surface (47) is designed flat, - the first side surface (47) regarding to an imaginary line (vertical (V)) which is vertical to the axis of rotation (43), is so inclined that the cutting insert (1) is aligned to contact the side surface (47) so that its cutting edge secondary (31) has a defined taper, wherein - the cutting plate (1) rests flush on their contact surfaces (33) on the first side surface (47) and that - in the base (45) of the seat the insert (39) is provided a hole, through which the adjusting piece (69) into the seat for the insert (39) projects, and in that the blade insert (1) on its side facing the adjusting piece (69) is preferably supported exclusively against it.
