Ruko Din 338 Hss Ground Self-centering Helical Ø 9 Mm Metal Drill Bit 10 Units. RUKO DIN 338 HSS Ground Self-Centering Helical Ø 9 mm Metal Drill BitUnleash professional precision and superior performance in your drilling applications with the RUKO DIN 338 HSS Ground Metal Drill Bit. Expertly engineered for professionals and demanding enthusiasts, this 9 mm high-performance drill bit is the definitive choice for creating clean, accurate holes in a wide array of common materials. Its robust construction and intelligent design ensure exceptional durability and efficiency, making it an indispensable accessory for any electric tool kit. Whether working in a professional workshop or on a critical project, this drill bit delivers reliability and flawless results.Experience the advantage of perfect centering from the very first touch. The bit features a precisely engineered conical point grinding with a split point according to DIN 1412 C. This advanced self-centering tip immediately bites into the material, preventing the frustrating ´walking´ or wandering common with standard bits. This key feature eliminates the need for a center punch or pilot hole, saving you valuable time and guaranteeing that your holes are placed with pinpoint accuracy every time.Crafted for excellence, the entire body of the drill bit is fully ground from a single piece of high-speed steel (HSS). This meticulous manufacturing process guarantees high concentricity and exceptional rotational accuracy, minimizing vibration and delivering a smoother drilling experience. The result is a perfectly round, high-quality hole with clean edges. The Type N point geometry is optimized for good centering while requiring lower feed pressure, reducing user fatigue and wear on your power tool.This versatile individual drill bit is a true workhorse, designed to handle an extensive range of materials with ease. It is the ideal tool for drilling into alloyed and unalloyed steel and cast steel with a tensile strength up to approximately 900 N/mm², as well as gray cast iron, malleable cast iron, nodular cast iron, die-cast iron, and sintered iron. Its capabilities also extend to non-ferrous metals, providing outstanding results in nickel silver, graphite cast iron, aluminum alloys, bronze, and brass. The bright surface finish reduces friction and aids in material ejection. Its capability for a drilling depth of 5 times its diameter makes it perfect for professional work in both metal and plastics.Technical Specifications:* Diameter (Ø): 9 mm* Standard: DIN 338* Material: High-Speed Steel (HSS)* Point Type: Conical point grinding with split point according to DIN 1412 C* Point Angle: 118°* Spiral Angle: 20-30º* Diameter Tolerance: h8* Finish: Bright surface* Cutting Direction: Right-hand cut* Application: Metal, Steel, Cast Iron, Aluminum, Brass, Bronze, Plastics* Drilling Depth: Up to 5 x diameter. tradeinn Bricoinn
