Abstract: A mounting assembly adapted for attachment to a surface of a rotatable driving member of a cutting tool machine and adapted for receiving a cutting tool includes: a base having a bottom portion for attachment to the surface of the rotatable driving member and a front portion that defines a bore; and a tool holder configured for mounting to the base. The tool holder includes: a leading head region having a forward face that defines an aperture for receiving the cutting tool; a trailing shank region with a central longitudinal axis and having an axial forward end and an axial rearward end; and a mediate region intermediate of and contiguous with the leading head region and the trailing shank region. The trailing shank region includes an anti-rotation portion and a mounting retention portion.

Abstract: A cutting tool mounting assembly adapted for receiving a cutting tool includes a base having a bottom portion and a front portion that defines a receptacle having an inner wall and a bushing configured for receipt in the receptacle of the base. The bushing includes: a forward face defining an aperture for receiving the cutting tool; a shoulder generally opposite the forward face, the shoulder configured for cooperating with the front portion of the base; and a shank portion extending rearward from the shoulder, the shank portion having an outer surface configured for cooperating with the inner wall of the receptacle. A first elastomeric layer is positioned between the shoulder of the bushing and the front portion of the base and a second elastomeric layer is positioned between the outer surface of the shank portion and the inner wall of the receptacle.
