Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If alloy content ≤0.2% Cr/Mo/W or ≤0.1% V
Lower alloy composition shifts to other milling tools subheading without high alloy specs.
If sold as individual replacement parts without cutting edges
Base metal parts of milling tools excluding the cutting portion classify separately.
If for use in industrial knife sharpening machines
End use determines classification if specifically for knife manufacturing equipment.
