    • The invention relates to a rotatably drivable cutting tool, preferably embodied as a fine machining tool having an integrated coolant/lubricant supply system, for machining bores, preferably throughbores. The tool, preferably embodied as a reamer, has a cutting part (324) on which a plurality of blades or cutting edges and flutes (320) are configured, and a shank (326) which configures a chucking section 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 (338) corresponding to the number of flutes are configured in the chucking section, said channels having respective axial discharge openings (342) and leading along the shank to respective associated flutes of the cutting part.
    • 公开了一种可旋转地驱动,切割工具,优选地在配置为一个集成的冷却剂/润滑剂供给微细加工工具,用于加工孔,优选地通过孔。 所述的工具,例如,在本实施方式中作为扩孔钻具有从切削部分一侧的卡盘上形成一个侧遥控器上的其上形成有多个叶片或切削刃和容屑槽(330)的切割部分(324)和轴(326) , 用于切削的更有效的供应有冷却剂/流体边缘,同时提高了制造工艺的经济性,一个数形成相应的(338)的冷却剂/润滑剂通道的数目每一个具有轴向出口开口(342),在卡盘部凹槽和沿轴 导致切割部分的相关联的笛。
