Ruko Din 340 Long Hss Ground Helical Ø 7.5 Mm Metal Drill Bit 10 Units. RUKO DIN 340 Long HSS Ground Metal Drill Bit | Ø 7.5 mm | For Deep DrillingExperience unparalleled precision and endurance for your most demanding deep drilling tasks with the RUKO DIN 340 Long Series Helical Drill Bit. Expertly engineered for professionals and craftsmen who require superior performance and reliability, this high-performance long series drill bit is the ultimate tool for creating deep, clean, and accurate holes in a variety of challenging materials. Its extended length and robust construction make it an indispensable accessory for metalworking, fabrication, automotive repair, and industrial maintenance.Unmatched Performance and DurabilityEngineered for excellence, this 7.5 mm drill bit delivers superior performance in a wide variety of metals. The core strength of its design ensures a high resistance to breakage, even under the significant stress of deep drilling applications. This durability translates into a longer service life and a more cost-effective solution for your workshop, providing consistent results project after project. Whether you are working with thick steel plates or complex cast iron components, this tool is built to withstand the pressure and deliver unwavering performance. The right-hand cut orientation is standard for most drilling operations, ensuring compatibility and ease of use with your existing electric tools.Optimized for Deep Drilling in MetalSpecifically designed as a long series drill bit according to DIN 340 standards, it is the ideal solution for making deep holes in thick materials or reaching difficult spots where standard length bits fall short. To achieve the best results and maximize the tool´s lifespan when making deep holes, it is recommended that small, incremental drill advances are made, punctuated by periodic retraction to ensure proper chip removal and prevent overheating. This technique guarantees a smoother, more precise bore and protects the integrity of the individual bit.Technical Specifications and Precision DesignEvery aspect of this drill bit is designed for optimal cutting action and precision.* Point Geometry: Features a precision conical point grinding with a classic 118º cutting angle, perfect for general-purpose drilling in a wide range of metals.* Helix and Flute Design: A carefully calculated helix angle of 20-30º, combined with the ground helical flutes, ensures smooth and efficient removal of chips from the borehole. This is critical for preventing clogging and maintaining a consistent cutting speed.* Exceptional Accuracy: Manufactured to a strict Ø-tolerance of h8, this drill bit guarantees highly accurate hole dimensions, essential for tasks requiring tight fits and precise assembly.* Surface and Finish: The bright surface finish reduces friction and material buildup, contributing to a cleaner cut and extending the tool´s operational life.Versatile ApplicationsThis individual drill bit demonstrates its remarkable versatility across a vast spectrum of materials. It is perfectly suited for drilling into alloyed and unalloyed steel and cast steel with a strength of up to approximately 900 N/mm². Furthermore, its robust design makes it highly effective on grey cast iron, malleable cast iron, nodular cast iron, die-cast iron, and sintered iron. It also excels when working with non-ferrous metals, effortlessly cutting through nickel silver, graphite cast iron, various aluminum alloys, bronze, and brass.The tool is presented in a practical, translucent plastic case with a blue background label, which allows for quick identification in a busy toolkit and provides excellent protection during transport and storage, ensuring your high-performance bit remains in perfect condition. tradeinn Bricoinn
