<p>A rotary cutting tool for reaming operations, including a generally cylindrically shaped tool shank with a longitudinal axis having a plurality of radially protruding and generally axially extending clamping wings, and a cylindrically shaped cutting head having a central bore and a plurality of axially extending cutting edges with an outer cutting diameter. The central bore has a plurality of circumferentially and alternately spaced bore sectors and bore recesses, where each bore sector has an outwardly inclined female clamping surface in clamping contact with an outwardly inclined male clamping surface of each clamping wing. A cylindrical shaped locking sleeve and a cylindrical shaped clamping nut assembled to the tool shank provide a means to adjust the clamping contact forces and the cutting diameter of the cutting head, and also enable removal and replacement of the cutting head without removal of the locking sleeve and clamping nut.</p> |
