"For ALL Milling applications These arbors are made up of 4 pieces consisting of the arbor, the arbor holder, and a coupling nut & a drive key. It works on a pull through principle. Your cutter slips onto the arbor & key, the arbor’s threaded stem is then pushed through the holder and drawn up by the coupling nut at the opposite end of the holder."

About the Dealer
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 inserted 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 tightening 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.
