DIN tungsten 5XD carbide internal cooling drill bits
DIN Tungsten 5XD Carbide Internal Cooling Drill Bits are manufactured to strict DIN standards for high accuracy and consistent CNC performance. Made from ultrafine-grain tungsten carbide, they provide hardness, rigidity, and thermal stability for deep-hole drilling in stainless steel, alloy steel, hardened materials, titanium, and high-temperature metals. Optimized flutes ensure smooth chip evacuation, while internal cooling channels reduce heat and wear. Coating options like TiAlN, AlTiN, and nano-composites extend tool life. Ideal for aerospace, automotive, mold making, and precision engineering, these drills deliver reliable deep-hole accuracy and long-term stability.
