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