8207.50.40 - Suitable for cutting metal, and parts thereof

This HTS category, 8207.50.40, specifically encompasses tools designed for drilling operations that are not intended for rock drilling or earth boring. These tools are constructed from base metal or incorporate base metal components and are suitable for cutting metal. This definition distinguishes them from other interchangeable tools for hand tools or machine tools that are not designed for drilling or are intended for different materials like rock.

The distinction from sibling categories is crucial. While 8207.50.40.00 covers tools *suitable for cutting metal*, the sibling category, 8207.50.90.00, covers tools *not suitable for cutting metal*. Therefore, the primary classification criterion here is the tool's functional capability to cut metal through a drilling action.

Within this category, further subclassification exists to provide more granular detail. The subcategories, 8207.50.40.30 (Twist drills) and 8207.50.40.60 (Other), allow for the segregation of common types of metal drilling tools from less standard or specialized ones. Twist drills represent a widely recognized and utilized form of drilling tool, while the "Other" category serves as a catch-all for any other metal drilling implements that do not fit the specific definition of a twist drill.
