Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If considered 'other special attachments' rather than strict dividing head
Broader category for similar rotary attachments without precise indexing features.
If for industrial machinery not principally machine tools
Could apply if principally used in semiconductor wafer prep equipment outside 8456-8465 scope.
If imported as unfinished cast iron housing
Unmachined castings for dividing heads classify by material before completion as tool parts.
