The tool has a shaft (12) has an oblong channel (17) for the coolant/lubricant. A cutting head (13) has a cutter (19) and chipping space whereby a section (22) of this space tapers towards the end side (18) of the cutting head. The narrowest cross-section of the chipping space is in the area of the main cutter (23). The tapering cross-section changes into an adjoining section (21) of the chipping space which preferably has a larger cross-section than the narrowest cross-section. |
