Claim 17:
18. The drilling tool according to claim 1, wherein the radial distances (r1, r2, r3) of the chip dividers from the tool axis (A) are different at at least two of the n drill cutting edges in such a way that:
the radial distance of the chip divider at one of the two drill cutting edges at its innermost point closest to the tool axis is greater than the radial distance of the chip divider at the other of the two drill cutting edges at its outermost point furthest away from the tool axis, and/or
the outer radial distance (r3) of the chip divider at one of the two drill cutting edges is smaller than the inner radial distance (r1) of the chip divider at the other of the two drill cutting edges.
