  • Patent number: 4074594
    Abstract: A rotary cutter, in the nature of a milling cutter, especially for agglomerated foam plastic, has a body with a concentric surface of revolution onto which are brazed block-like carbide cutting elements. The cutting edges of circumferentially adjacent cutting elements lie on lines spaced apart circumferentially by between 0.60 in. (15 mm.) and 0.165 in. (17 mm.), and the kerfs of such cutting elements overlap. The cutting elements are received in shallow axially extending grooves in the body; their axial locations are established by reference to lines scribed around the body at uniform axial intervals.
