ABSTRACT:
A tool for rotary chip removal machining includes a cutting head, a retention element and a shank. The cutting head includes a rear mounting portion and the retention element includes a front retaining portion. The mounting and retaining portion present forwardly facing and rearwardly facing surfaces, respectively, which engage one another for retaining the cutting head in the shank. The hook of the cutting head is asymmetrical with respect to the axis and is larger than the hook of the retention element. The cutting head includes a central flushing channel for conducting a flushing medium. The channel extends through the mounting portion of the cutting head for reducing the mass of that hook. The retention element includes a central channel which does not extend through the retaining portion.
