8207.50.20.55 - Other

This HTS category, 8207.50.20.55, specifically covers "Other" twist drills with a cutting part containing by weight over 0.2 percent of chromium, molybdenum, or tungsten, or over 0.1 percent of vanadium. These are tools designed for creating holes in various materials, excluding those intended for rock drilling. The key characteristic is the alloy composition of the cutting edge, which imbues the drill with enhanced hardness, wear resistance, and heat tolerance, making them suitable for more demanding drilling applications.

Within the broader classification of twist drills with these specific alloy compositions, this "Other" designation serves as a residual category for twist drills that do not fit into more specific sub-classifications at this level. For instance, it is distinct from the "Brad point" twist drills (8207.50.20.45), which are specifically designed with a central point and spurs for precise starting and cleaner entry into wood, minimizing splintering. Therefore, 8207.50.20.55 would encompass twist drills that do not possess this brad point feature, such as general-purpose twist drills made from high-speed steel or similar alloys meeting the specified chromium, molybdenum, tungsten, or vanadium content.

As this is a leaf node, there are no further subcategories. Classification at this level relies on meeting the alloy criteria and not fitting the more specific "Brad point" description. Importers and exporters should meticulously verify the metallurgical composition of the cutting element to ensure accurate classification under this provision.
