Abstract
An end prep tool with a pneumatically driven tool slide assembly comprises a mandrel mountable to the internal diameter of a tubular work piece. Mounted on the mandrel are a rotational head assembly and a rotatable housing that are longitudinally displaceable along the mandrel. The rotational head assembly carries either one or two tool feed assemblies thereon for orbital movement around the work piece. The tool slide assemblies are driven by a pneumatic motor to provide a true phonographic finish with no tripper marks.
