FIELD: process engineering.
SUBSTANCE: invention relates to suppression of vibrations in electrically driven hand-held machines. Hand-held machine comprises vibration killer including first damper with first damping direction and second damper with second damping direction. First damping direction is in fact parallel with second damping direction. Vibration intrinsic frequency of first damper differs from that of second damper. Said dampers are arranged one after another in damping direction.
EFFECT: compact design, efficient damping.
