FIELD: mechanical engineering; metal working and cutting. ^ SUBSTANCE: proposed tool has housing in which cutting blade with hole is secured in angular socket by means of rod with head and nut installed on thread on end of rod in contact with end face of bushing installed in stepped hole of housing. To improved operation reliability owing to guaranteed direction of clamping force of cutting blade to angle of housing socket, axis of rod is displaced relative to axis of hole in cutting blade in direction of top of angular socket, and stepped hole is provided with section having conical surface. End face of bushing opposite to end face in contact with nut is made spherical to provide contact with said conical surface of stepped hole from side opposite to top of angular socket. Centering belt is made in bushing near its spherical end face on inner diameter. Said belt in contact with rod. ^ EFFECT: improved operation reliability of tool. ^ 2 dwg |
