Abstract
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.
