8207.70.60.30 - End milling cutters

This HTS subcategory, 8207.70.60.30, specifically classifies end milling cutters. These tools are designed for use with machine-tools, and their primary function is to remove material from a workpiece through a rotating cutting action, creating flat surfaces, slots, or contours. End milling cutters are characterized by their cutting edges located on the end face as well as the periphery.

This classification distinguishes end milling cutters from their sibling category, 8207.70.60.40, which covers router bits specifically designed for non-metal applications. While both may have rotating cutting elements, the key differentiator here is the intended material to be cut. This HTS code is for cutters designed for metalworking. It also differs from 8207.70.60.60, which is a broader category for "Other" milling tools and parts thereof, thus capturing a wider range of milling implements beyond end milling cutters.

As this is a leaf node in the HTS database, there are no further subcategories. Classification under 8207.70.60.30 is definitive for end milling cutters intended for use with machine tools in metalworking operations.
