Abstract
A rotary bit having a pair of semi-spheres (18, 20) rotatable about a shaft extending from a center tongue (14). The semi-spheres include a plurality of cutters (22, 24) arranged in a predetermined fashion to maximize cutting efficiency. The semi-spheres may be disposed slightly off-center from the bit’s axis of symmetry to bias the bit in a particular direction.
