<p>The invention relates to a rotating shank-type tool (11) with a shank (12), in which at least one main channel (21) for coolant/lubricant extends in the longitudinal direction of the shank and from which, in the end region of the main channel, at least one branch channel (22) leads outward and forms a mouth (23). A cutting head (13) is connected to the shank (12) and has chip grooves (15) and a groove run-out region (16). A sleeve (19) engages over the mouth (23). The end region of the sleeve (19) covers at least the groove run-out region (16) of the cutting head (13). The branch channel mouth (23) is positioned in the shank at a distance from the cutting head (13).</p> |
