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.

- at least one pocket in the tool body for supporting a cutting insert, the pocket being defined, at least in part, by a cylindrical wall and a seating surface within the tool body;
- at least one passage through the tool body, the seating surface from the pocket extending radially inward from the cylindrical wall and intersecting the passage;
- and
- at least one slot in the tool body that 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.
A cutting tool that is adapted for use in milling operations, the cutting tool comprising:
- a tool body comprising:
- a working end with at least one pocket in the tool body, the pocket being defined, at least in part, by a cylindrical wall and a seating surface in the tool body;
- and
- a passage within the tool body, the seating surface extending radially inward from the cylindrical wall and intersecting the passage;
- and
- at least one slot in the tool body that traverses the pocket to separate a part of the tool body into first and second portions, wherein one portion is movable relative to the other portion;
- and
- a cutting insert held within the pocket by a clamping screw that is adapted to be inserted in a first hole through the first portion of the tool body and threaded into a second hole through the second portion of the tool body, whereby tightening the screw draws the two portions toward one another to clamp the tubular cutting insert in the pocket.
