Abstract

A tool-locking device with two locking discs and a common locking screw for securing a tool sleeve between the two locking discs. The two locking discs have concentric annular grooves for securing tool sleeves of the same diameter and made of a flexible material. Surprisingly, flexible tool sleeves of this type experience rotational stabilisation about their central rotational axis without a rubber core or suchlike supporting body having to be used. As a result of the rotational stabilisation, a cylindrical tool face is always retained. <IMAGE>
