FIELD: different types of powered tools with lowered vibration degree. ^ SUBSTANCE: tool includes head, drive mechanism and unit for dynamic lowering of vibration. Drive mechanism imparts linear motion to tool head due to pressure oscillations for providing preliminarily set action of head. Unit for dynamic lowering of vibration includes weight performing reciprocation motion by action of shifting force of elastic member in order to reduce vibration of drive mechanism. Said weight may be activated by means of pressure oscillations in drive mechanism of tool head. ^ EFFECT: possibility for forced suppression of vibration regardless of vibration intensity. ^ 12 cl, 18 dwg
