A billet manipulating apparatus for the selective presentation of a billet to the operative grinding surface of a grinding wheel. An assembly of three billet-engaging arms functions to remove the billet to be ground from a charge table and position it in any one of a number of grinding positions, one arm effecting transfer of the billet from the table to the other two arms which then function to rotate or tumble the billet until the desired side or edge to be ground is presented to the associated grinding wheel.
