The cutting tool shown generally as (1), has a disc with a peripheral cutting face. In this embodiment the cutting face includes an array of eight circumferentially spaced teeth (2). An open circumferential gutter (5) is located inboard of the teeth and is recessed into a lateral face of the disc. Fluid in the gutter drains into the passageways through the respective inlets under the apparent force due to rotation. A fluid passageway (9) runs between the gutter and the base of the each tooth. The fluid is thereby forced through the passageway and out of outlet (11).
L'invention porte sur un outil de coupe (1) consistant en un disque dont la face de coupe périphérique comporte huit dents (2) réparties régulièrement sur la circonférence. Une rainure circonférentielle ouverte (5) située à l'intérieur de chaque dent est en retrait par rapport à la face latérale du disque. Le fluide présent dans la rainure s'écoule passe dans des passages via leur entrées respectives sous l'effet de la force centrifuge. De tels passages (9) relient la rainure à la base de chacune des dents. Le fluide ainsi entraîné dans les passages ressort par les sorties (11).
