ABSTRACT:
An improved cutting bit and associated holding block assembly for use on rotary wheel, chain or rotor cutters of the type having a plurality of cutting bits projecting outwards from the periphery of the wheel, chain or rotor and used to cut tree stumps or other hard or refractory materials includes individual holding blocks which each rotatably support within a bore therewithin a separate cylindrical cutting bit. The bore is canted inwards with respect to a radius of the wheel, chain or rotor, thus causing the outermost portion of a rotatable bit held in the bore to contact a surface to be worked at a negative top rake angle as the bit is rotated into contact with the work surface. The negative top rake angle advantageously provides clearance for chips severed by the bit. However, the dihedral angle between the outer transverse wall surface of the circular cutting bit tip and its outer tapered side wall is sufficiently acute as to present an effectively sharp angle between the cutting edge of the tip and the surface being worked.
