FIELD: tools.
SUBSTANCE: invention relates to a cutting tool in the form of insert cutter (3) and replaceable cutting plate (4), as well as key (20) having eccentric body (21). Cutting plate (4) can be clamped in socket (8) under the action of resilient clamping finger (10). Cut-out hole (13) is formed in the cutter, into which eccentric body (21) can be inserted. Concave sliding surfaces (27) that are adjacent to flat thrust surface (28) are included in key hole. Convex corner surfaces (34) and flat shoulder surfaces (32) on the eccentric body can interact with them.
EFFECT: smooth interaction is achieved between the key hole in the insert cutter and the key, which increases the service life of the insert cutter and key.
