FIELD: process engineering.
SUBSTANCE: set of invention relates to machine building and can be used for machining by tool with replaceable cutting edges at high feeds. Proposed tool comprises body, plug-in inserts and multiple insert seats with surface of bottom wall and multiple sections of top walls hanging above appropriate insert seat and having side surface defining the chips pocket. Every said section hangs over to cover at least the insert part in said seat and is configured so that amount of hanging over on base side is larger than that whereat top wall section hangs over the insert seat on its front end. Top wall section is formed to increase the depth of section for support of insert in said seat abutting on appropriate insert seat and extends from insert seat bottom wall surface to abut on appropriate insert seat and on top wall section side surface.
EFFECT: higher hardness of cutting tool, better removal of chips.
