Abstract
Tool extension and stability in milling machines is enhanced by providing a spindle extension having a housing attached to the mill head and an arbor rotatively mounted in a bore formed in the housing. The arbor, which is significantly longer than conventional arbors, is supported by first and second bearing assemblies and includes a substantially cylindrical body portion with an integral shank formed on one end thereof for connecting the arbor to a machine tool spindle. A cutting tool is attached to the other end of the arbor.
