摘要

FIELD: high rotation number tools such as drills and milling cutters. SUBSTANCE: tool includes at least two balancing rings having different mass along their perimeter and radially directed support on their peripheral surface. EFFECT: lowered length of tool due to improved arrangement of balancing rings, elimination of possibility of disrupture of balancing rings by centrifugal forces due to securing them at least partially along outer periphery. 9 cl, 3 dwgi
