8207.50.40.30 - Twist drills

This HTS subcategory, 8207.50.40.30, specifically classifies twist drills designed for cutting metal. These tools are integral to machining operations, enabling the creation of holes in various metal workpieces. The defining characteristic of this classification is the tool's primary function and design for metal removal through a rotational cutting action.

Distinguishing this category from its sibling, 8207.50.40.60 ("Other"), is crucial. While the sibling category encompasses a broader range of drilling tools not specifically designed for metal cutting or other unspecified drilling applications, this subcategory is narrowly focused on those twist drills engineered with geometries, materials, and cutting edges optimized for piercing and widening holes in metallic materials.

As this is a leaf node, there are no further subcategories. Therefore, classification under 8207.50.40.30 relies on the precise identification of the article as a twist drill intended for metal cutting. Classification considerations would include the tool's physical form factor (spiral flutes, point angle), the material it is intended to cut (metal), and its intended use in conjunction with either hand tools or machine tools.
