ABSTRACT:
A cutter body includes an elongate, generally cylindrical chuck for gripping a cylindrical cutter, an annular cutting fluid gland surrounding the chuck, and retaining means for securing the gland longitudinally on the chuck. The cutter has a longitudinal bore therethrough defining a fluid passageway. The chuck has a longitudinal bore at least partially therethrough for gripping the cutter and defining a fluid passageway. The bore of the chuck is in fluid communication with the bore of the cutter. The chuck includes opposed ends and a medial portion disposed between the opposed ends. The medial portion includes longitudinally spaced-apart, circumferential lands which define bearing surfaces for engaging the inner surface of the cutting fluid gland. The medial portion has an opening therein defining a fluid passageway. The gland has an opening therein defining a fluid passageway. The opening of the gland is in fluid communication with the opening of the medial portion of the chuck, and the opening of the chuck is in fluid communication with the bore of the chuck. Accordingly, the opening of the gland, the opening of the medial portion of the chuck, the bore of the chuck and the bore of the cutter define a continuous fluid passageway for delivering the cutting fluid to the cutting portion of the cutter and the workpiece.
