Abstract
The invention relates to a shank bit for a road milling machine or the like, having a bit head and a bit shank, the bit shank comprising a first cylindrical segment that is indirectly or directly adjacent to the bit head, and the bit shank comprising a second cylindrical segment that, facing away from the bit head, is indirectly or directly adjacent to the first cylindrical segment, and the diameter of the second cylindrical segment differing from the diameter of the first cylindrical segment. In a shank bit of this kind, improved utilization properties result from the fact that the first cylindrical segment has a diameter in the range between 18 mm and 30 mm, and an extent in the direction of the longitudinal center axis of the bit shank less than 30 mm.
