TOOL BODY AND CUTTING INSERT FOR METAL CUTTING OPERATIONS

摘要

A cutting tool body (10) that is adapted for use in milling operations comprises at least one pocket (22) for supporting a cutting insert. The pocket (22) is defined, at least in part, by a cylindrical wall (26) and a seating surface (28) within the tool body (10). At least one passage (30) is provided through the tool body (10) for evacuating chips upward and away from the surface of a workpiece (W). The seating surface (28) of the pocket (22) extends radially inward from the cylindrical wall (26) and intersects the passage (30) through the tool body (10). At least one slot (32) traverses the pocket (22) to separate a part of the tool body (10) into first and second portions (34, 36), at least one of which is movable relative to the other for clamping the cutting insert into the pocket (22).
