The single-phase collector motor of the angle grinder is reliably protected from construction dust and inter-turn short circuits by means of multi-layer impregnation of the armature and stator windings with heat-resistant varnish. Inside the narrow-profile metal gearbox housing is a metal bevel gear, whose helical teeth provide a better contact area to reduce noise, vibration, and extend service life. The high hardness of the impact-resistant plastic housing also increases the tool's reliability. Its compact size allows for easy control of the angle grinder in confined spaces and working with complex structures.
