The Walter Surface Technologies 7684349 Extra Long Drill Bit is engineered for precision drilling in deep-hole applications, offering exceptional performance and durability. Designed with a 10 mm diameter and a 262 mm overall length, this carbide-tipped drill bit is ideal for tasks requiring extended reach and accuracy. The spiral flute design facilitates efficient chip removal, reducing the risk of clogging and ensuring a cleaner hole finish. Its right-hand cutting direction and two-flute configuration enhance stability and control during operation. The TiSiAlCrN/AlTiN coating provides superior hardness and wear resistance, extending tool life and maintaining sharpness over prolonged use. Equipped with coolant-through capability and two coolant holes, the drill bit ensures effective cooling and lubrication, minimizing heat buildup and enhancing cutting efficiency. The 140, point angle allows for precise centering and reduced thrust force, while the H7 tolerance ensures a tight fit for high-precision applications. With a 20xD depth-to-diameter ratio, this drill bit is suitable for deep-hole drilling tasks, offering consistent performance and reliability. The straight shank design and 40 mm shank length provide compatibility with a wide range of drilling machines, making it a versatile tool for various industrial applications. The 205 mm maximum drilling depth and 118, point angle further contribute to its capability in handling complex drilling operations. The 2.00 mm point length and 45 mm shank length offer additional stability and control, ensuring accurate and efficient drilling. The decimal equivalents of 0.3937 in and 0.4331 in correspond to the metric dimensions, facilitating easy conversion and compatibility with standard measurement systems. This drill bit is an essential tool for professionals seeking high-quality, reliable, and efficient solutions for deep-hole drilling tasks.
