<p>The invention relates to a rotatably drivable cutting tool, preferably embodied as a fine machining tool, such as for example a high-speed reamer, having an integrated coolant/lubricant supply system, for machining bores, preferably throughbores. The tool has a cutting part (124) on which a plurality of blades or cutting edges and flutes are configured, and a shank (126) which configures a chucking section (122) on a side facing away from the cutting part. The aim of the invention is to more efficiently supply the cutting edges with coolant/lubricant and to improve the cost-effectiveness of the production method. To achieve this aim, a number of coolant/lubricant channels (138) corresponding to the number of flutes are configured in the chucking section, said channels having respective axial discharge openings (142). The coolant/lubricant issued from the coolant/lubricant channels is fed to the associated flutes of the cutting part in a practically free-floating manner, optionally supported by the outer diameter of the shank.</p> |
