Percussive electric hand power tool e.g. chisel hammer, has ferromagnetic percussive element with stop surface whose cross-sectional area corresponds to half of cross-sectional area of abutting surface of ferromagnetic plunger

摘要

The tool (1) has a plunger coil (3) in which a coaxial coil axially moves, and a ferromagnetic plunger (4) with an abutting surface. The ferromagnetic plunger is assigned to a stop surface of a ferromagnetic percussive element (5) in an axial internal area of the plunger coil in an adjacent manner. The cross-sectional area of the stop surface, corresponds to half of the cross-sectional area of the abutting surface. The ferromagnetic plunger and the percussive element are made of shockproof, soft-magnetic material.
