8466.10.01.30 - Holders for replaceable cutting or drill inserts

This HTS category, 8466.10.01.30, specifically covers holders designed for replaceable cutting or drill inserts. These are essential components used to securely hold interchangeable cutting tools or drill bits within various machining operations. Examples include tool holders for milling inserts, turning inserts, and boring inserts, as well as chucks designed to hold replaceable drill bits. The primary function is to facilitate the easy and precise mounting and changing of these consumable cutting elements.

Distinguishing this category from its siblings, 8466.10.01.10 covers tool holders specifically designed for forming-type or cutting-type dies, which are used to shape materials rather than cut them. The sibling 8466.10.01.75 represents a residual category for "Other" tool holders and self-opening dieheads that do not fit into the more specific subheadings. Therefore, 8466.10.01.30 is distinct by its focus on holders for *replaceable inserts* which are designed to be swapped out for different operations or to be replaced when worn.

As this is a leaf node within the HTS, there are no further subcategories under 8466.10.01.30. Classification at this level relies on the definitive characteristic of the tool holder: its suitability for use with replaceable cutting or drill inserts. The absence of further subdivisions indicates that all such holders fall within this single code, provided they meet the description and are not specifically classified under the sibling categories.
