Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If other gear cutting tools not specified as hobs
Non-hob gear cutters like broaches fall under the residual 'other gear cutting tools' subheading.
If for use solely in industrial gear finishing machines
Machinery-specific finishing tools without interchangeability classify as machine parts under 8438.
If with cutting part of powdered metal only
Powder metallurgy tools without specified alloys go to separate cemented carbide subheading.
