Abstract
A cutting tool assembly having a holder block mounting scheme which effectively and accurately positions the cutting tip point at its designed angle of attack. The connection assembly limits undesirable shifting during attachment of the holder block to a cutting drum. The holder block connection assembly of the present invention includes a separate mounting plate that is positioned between the bit holder block and drum/pedestal for accurately aligning the bit holder block onto to the drum/pedestal. Once the bit holder block is aligned into position by the plate as designed the bit holder block is welded to the drum/pedestal.
