The drill press version comes with a base that bolts to your head stud holes, and the shank and stop collar (so you get the hole depth the same, and centered on all cylinders every time
) this cost about $275 US
in a 2000 copy of Berg price list I have, maybe higher now though. It includes everything need, but drill press.
