The cutting member includes a hub having a cylindrical bore formed about a central longitudinal axis. A plurality of first fingers are attached to the hub and extend generally radially outwardly from the hub in a direction perpendicular to the longitudinal axis. The plurality of first fingers are located in a generally circular manner about the hub. A plurality of second fingers are attached to the hub in a generally circular manner about the hub and extend generally radially outwardly from the hub in a direction generally perpendicular to the hub. Each second finger is located in a rotated position about the longitudinal axis of the hub with respect to a respective first finger. Each first finger and each second finger is respectively formed as a truncated rectangular pyramid having a plurality of side cutting surfaces, wherein each side cutting surface includes a pair of side cutting edges and a tip cutting edge.
