The Nachi AQRVD0H8D1600 is a new, solid carbide AquaREVO through-coolant twist drill from Nachi's LIST9868 series, manufactured in Japan to XL25 tolerance grade. The part number decodes as: AQRVD = AquaREVO drill series, 0H8 = 8xD depth-of-cut (long series), D1600 = 16.0 mm cutting diameter; dimensional specs confirmed on label as 16.0 mm diameter × 180 mm flute length × 242 mm overall length × 16 mm shank diameter. The drill features Nachi's proprietary dark multi-layer coating (visible in the product photo as a blue-black finish), internal coolant-through channels for high-pressure coolant delivery to the cutting edge, and is designed for deep-hole drilling in steel, cast iron, and stainless steel on CNC machining centers using ER or hydraulic chucks sized for a 16 mm straight shank. The 8xD aspect ratio is suited for deep-hole operations where chip evacuation and tool life are critical, leveraging through-coolant to clear chips and reduce heat at depth.
