Colorful coating carbide drill bits
Wholesale Custom Colorful Coating Carbide Drill Bits are designed for high-performance CNC drilling, combining ultrafine-grain tungsten carbide durability with visually distinctive coatings for easy identification. Optimized flute geometry and balanced cutting edges ensure smooth chip evacuation, reduced cutting forces, and precise hole quality on stainless steel, alloy steel, cast iron, aluminum, and composites. Colorful coatings such as rainbow PVD, TiAlN, AlTiN, and nano-composites enhance heat resistance, reduce friction, and extend tool life. Fully customizable in diameter, flute length, point angle, shank type, coatings, tolerance, and geometry, ideal for automotive, aerospace, mold, and precision engineering applications.
