The elongated body member has a head end having a step shaped surface thereon on which is disposed a plurality of generally radially extending ribs disposed at equal angular increments. The ribs extend through an arc of 360 degrees. A first head assembly has a lower extremity which includes a surface having a plurality of generally radially extending ribs disposed at equal angular increments thereabout. These ribs are uniformly spaced and dimensioned and configured for cooperation with the ribs of the body portion. The ribs of the head assembly and the body portion have the same angular spacing therebetween. The head assembly includes discrete means for holding a cutter insert and means for holding the head assembly on the body portion.
