Abstract

An angle grinder with a housing 2 can be produced more economically by providing that it has a mounting shell 3, a cap shell 4, and an insert part 1 between these two shells. The insert part 1 is equipped with a first fixation device 10 and a second fixation device 11 for fixation between the mounting shell 3 and the cap shell 4, and it has a spindle locking receptacle 12 and spindle bearing receptacle 13. The mounting shell 3 has a first fixation means 30, which is engaged by the first fixation device 10 of the insert part 1. The cap shell 4 has a second fixation means 40, which engages the fixation device 10 of the insert part 1. The insert part 1 also has a second fixation device 11, which can be brought into engagement with suitable means on the mounting shell 3 and the cap shell 4.
