The shank end with the internal thread is to fit into the hob holder. The internal thread fastens
the hob tool in place, (a screw holds the cutter in place). The opposite end is used in a pillow block type holder which keeps the cutter running true. The center(actually on both ends except one end has an internal thread as well) is used for grinding the bearing surfaces into concentricity as well as sharpening the cutter when needed. What is the diametral pitch of the cutter as well as other information (pressure angle and number of threads, worm gear cutter? ect) I may have one in my inventory of cutters.
We have been arround since 1950 so we have several cutters.
