摘要： A bit assembly includes a bit having a bit head and a bit shank, a mounting sleeve being held in the region of the bit shank, and a support element that comprises a guidance region being associated with the bit. To allow the bit to be easily deinstalled from the bit receptacle and allow it, if applicable, to be easily installed again, provision is made that the support element comprises, in the region of its underside facing away from the bit head, a deflection segment.

摘要： 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.

摘要： The present invention relates to a pick, in particular, a round shaft pick, having a pick head and a pick shaft, having a support element which has a centering lug on the underside thereof, wherein the centering lug has a centering surface which extends inclined with respect to the central longitudinal axis of the pick and merges into a seat surface. To this end circumferential channel according to the present invention is disposed in the transition region from the centering surface to the seat surface and the depth of the channel relative to the seat surface is greater than or equal to 0.3 mm. The pick has an optimised rotatability and thus a low wear.
