Drilling Tools (Non-Rock), Base Metal

Brad-point twist drills with cutting parts meeting specified alloy content thresholds have their own 10-digit line (8207502045), while standard twist drills suitable for cutting metal classify under 8207504030 regardless of point geometry. The alloy-content lines (8207502xxx series) apply when the cutting part contains the specified minimum percentages of chromium, molybdenum, tungsten, or vanadium; drills not meeting those thresholds fall into the non-alloy-specific lines.

Multi-material drill bits are classified based on their primary design and suitability. If the bit is engineered and marketed primarily for cutting metal, it would typically fall under a metal-cutting line such as 8207504030. Bits designed primarily for wood or masonry, even if capable of light metal work, would classify under the appropriate non-metal lines. Importers should document the manufacturer's intended use and product specifications to support their classification.
