Abstract

A tool-handling device for an insert tool(14) equipped with an at least essentially disk-shaped hub (42), in particular for a hand guided angle grinder (32) or a hand-guided circular saw, having a drive shaft (16) and a drive device (12) equipped with at least one locking element(20) that is supported so that it is able to move in relation to a spring element (18) in order to fix the insert tool (14) in a form-locked manner in the circumference direction (50, 52).The drive shaft (16) has at least one form-locking element (100) formed onto it in a non-cutting manner in order to connect it in a form-locked manner in the circumference direction (50, 52) to a drive torque-transmitting mechanism of the drive device (12).
