RUKO 2140475 Pack de 10 brocas helicoidales DIN 338, tipo N HSS, fresada rectificada, con autocentrado (Ø 4,75 mm)

Ruko Din 338 Hss Ground Self-centering Helical Ø 4.75 Mm Metal Drill Bit 10 Units. RUKO DIN 338 HSS Ground Self-Centering Metal Drill Bit | 4.75 mmAchieve unparalleled precision and efficiency in your metalworking projects with the RUKO DIN 338 HSS Ground Metal Drill Bit. Engineered in Germany for professionals and demanding enthusiasts who refuse to compromise on quality, this high-performance 4.75 mm drill bit is the ultimate solution for drilling in a wide array of common materials. Designed to be used with all types of drills, it delivers consistent, reliable results job after job. Each individual bit is a testament to superior manufacturing, ensuring you get the accuracy and durability required for professional work.Unmatched Precision and PerformanceExperience the difference that exceptional engineering makes. This drill bit is distinguished by its high concentricity and rotational accuracy, which translates to cleaner, more precise holes with minimal run-out. The fully ground body from a single piece of high-speed steel enhances this stability, ensuring smooth operation and a superior finish.The standout feature is its self-centering split point, ground to a conical shape according to DIN 1412 C standards. This advanced tip design bites into the material immediately upon contact, preventing the bit from walking or wandering. This eliminates the need for a center punch, saving you time and guaranteeing perfect hole placement on both flat and curved metal surfaces. The N-type point geometry further enhances this centering capability while requiring significantly lower feed pressure, reducing operator fatigue and wear on your power tool.Versatile Application Range for the Professional WorkshopThis is not just a drill bit, it is a versatile workhorse. Its design and robust HSS construction make it the ideal choice for a vast range of materials. It effortlessly drills through:· Steel: Alloyed and non-alloyed steel with a tensile strength up to approx. 900 N/mm².· Cast Materials: Grey cast iron, malleable cast iron, nodular cast iron, die-cast iron, graphite cast iron, and sintered iron.· Non-Ferrous Metals: Nickel silver, aluminum alloys, bronze, and brass.Whether you are fabricating, repairing, or performing general workshop tasks, this drill bit provides the cutting power and resilience needed to tackle demanding jobs with confidence. It allows for a professional drilling depth of up to 5 times the diameter.Technical Specifications:* Diameter: 4.75 mm* Drill Type: Individual Helical Twist Drill for Metal* Standard: DIN 338* Material: High-Performance HSS High-Speed Steel* Finish: Bright Surface, Fully Ground Body* Point Geometry: Split Point according to DIN 1412 C* Point Angle: 118°* Spiral Angle: 20-30º* Cutting Direction: Right-Hand Cut* Diameter Tolerance: h8* Rotational Accuracy: High Concentricity for Precise Drilling. tradeinn Bricoinn
