<p>The cutting tool shown generally as (1), has a disc with a peripheral cuttin g 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 inlet s under the apparent force due to rotation. A fluid passageway (9) runs betwee n the gutter and the base of the each tooth. The fluid is thereby forced throu gh the passageway and out of outlet (11).</p> |
