RUKO DIN 338 HSS Ground Self-Centering Helical Ø 4.5 mm Metal Drill BitExperience superior drilling performance and professional-grade precision with the RUKO DIN 338 HSS Ground Self-Centering Helical Drill Bit. Engineered for excellence, this high-performance 4.5 mm drill bit is the ultimate accessory for all types of drills, delivering flawless results in common materials. Its design is optimized for both stability and efficiency, making it an indispensable tool for professionals and demanding DIY enthusiasts who require reliability and accuracy in every task. Unrivaled Precision and Effortless StartingAchieve perfect holes from the very start. This drill bit features a conical point grinding with a split point according to DIN 1412 C. This advanced self-centering tip immediately bites into the workpiece, eliminating walking or skidding and ensuring exceptional positional accuracy without the need for a center punch. The N-form point geometry not only guarantees good centering but also significantly reduces the required feed pressure, allowing for smoother, faster, and less strenuous drilling. The fully ground body of the drill bit ensures high concentricity and rotational accuracy, minimizing vibration and producing cleaner, more precise holes. High-Performance Engineering for Demanding ApplicationsConstructed from high-performance HSS high-speed steel, this standard twist drill bit is built to withstand rigorous use. The bright, fully ground surface reduces friction and aids in chip evacuation for a more efficient cutting process. The cylindrical shank, manufactured to a precise h8 tolerance, ensures a secure and concentric grip in the drill chuck, preventing slippage and maximizing power transfer. With a right-hand cut and a specialized spiral angle of 20-30º, it efficiently removes material while maintaining stability, allowing for a professional drilling depth of up to 5 times the diameter. Exceptional Versatility Across MetalsThis individual drill bit is a master of metal applications. Its robust design makes it perfectly suitable for a vast range of materials. Confidently drill through alloyed and unalloyed steel and cast steel with a strength of up to approximately 900 N/mm². Its versatility extends to grey cast iron, malleable cast iron, nodular cast iron, die-cast iron, sintered iron, nickel silver, and graphite cast iron. It also performs exceptionally well on softer metals such as aluminum alloys, bronze, and brass, making it a truly universal solution for any metalworking project.Technical Specifications:* Diameter: 4.5 mm* Standard: DIN 338* Material: HSS (High-Speed Steel)* Point Grind: Conical with Split Point (DIN 1412 C)* Point Angle: 118°* Spiral Angle: 20-30º* Diameter Tolerance: h8* Surface: Bright* Cut Direction: Right-hand cut* Drilling Depth: 5 x Diameter* Primary Application: Metal* Shank Type: Cylindrical. tradeinn Bricoinn
