The Spirit Tool Arbor System offers the machinist two major advantages:
LOW PROFILE MOUNTING of cutters for truly versatile tool positioning, AND
EXTREMELY RIGID CUTTER MOUNTING for improved performance and accuracy.

In use, the cutter is positioned in the Arbor Assembly and is drawn together with the coupling nut which is only tightened "finger-tight", NO wrenches are required.

The Arbor Assembly is then into the spindle of the milling machine where it is retained in the usual manner by the drawbar. At this point, Spirit Tool's exclusive cutter holding feature permits all of the drawbar tighening force to be transmitted directly to the cutter faces. The tool, now an integral part of the quill, is ready for the most demanding performance in low-clearance work areas completely inaccessible to other arbors.
