Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If functions as tool holder for helical hobs
Arbors holding cutting tools vs workpieces determine work/tool holder distinction.
If finished as standalone transmission arbor
Arbors not principally for machine tools classify as transmission parts.
If basic unhardened steel arbor blanks
Interchangeable tool blanks without precision features fall in Chapter 82.
