RUKO 214003 Pack de 10 brocas helicoidales DIN 338, tipo N HSS, fresada rectificada, con autocentrado (Ø 0,3 mm)

Ruko Din 338 Hss Ground Self-centering Helical Ø 0.3 Mm Metal Drill Bit 10 Units. RUKO DIN 338 HSS Ground Self-Centering Metal Drill Bit Ø 0.3 mmAchieve unparalleled precision and efficiency in your most demanding drilling tasks with the RUKO DIN 338 High-Performance Metal Drill Bit. Engineered for professionals who require absolute accuracy, this 0.3 mm helical drill bit is the ultimate solution for working with a vast array of common materials. Its fully ground HSS body ensures exceptional rotational accuracy and high concentricity, translating to cleaner holes, reduced friction, and an extended tool lifespan. This is a high-performance standard twist drill bit designed for all types of drills, delivering consistent, reliable results every time.Experience the advantage of effortless and precise starts thanks to the conical point grinding with a self-centering split point, manufactured according to DIN 1412 C. This advanced tip design immediately bites into the material, eliminating the need for pre-punching or a center mark and preventing the bit from walking across the workpiece surface. The N-type point geometry also contributes to its excellent centering capabilities while requiring lower feed pressure, reducing user fatigue and improving overall control during operation, especially with a fine 0.3 mm diameter.Engineered for Professional Performance and VersatilityThe RUKO DIN 338 is not just a drill bit, it is a precision instrument. The cylindrical shank is manufactured with a strict h8 tolerance, guaranteeing a secure and precise clamping in any standard chuck, which minimizes run-out and maximizes drilling accuracy. Its right-hand cut and optimized 20-30º spiral angle ensure efficient chip evacuation, keeping the cutting zone clear and preventing overheating. The bright surface finish further aids in smooth material removal. Capable of a drilling depth of 5 times its diameter, it is perfectly suited for professional work on both metal and plastics, offering the depth required for a wide range of jobs.Broad Application SpectrumThis high-performance drill bit excels across an extensive range of materials. It is the ideal choice for drilling in alloyed and unalloyed steel and cast steel (up to a strength of approximately 900 N/mm²), grey cast iron, malleable cast iron, nodular cast iron, die-cast iron, and sintered iron. Furthermore, it demonstrates outstanding performance in non-ferrous metals, including nickel silver, graphite cast iron, aluminum alloys, bronze, and brass.Technical Specifications:* Diameter (Ø): 0.3 mm* Standard: DIN 338* Point Geometry: Conical Point Grinding with Split Point per DIN 1412 C* Point Type: Self-Centering, N-Type* Cutting Angle: 118°* Spiral Angle: 20-30º* Diameter Tolerance: h8* Shank Tolerance: h8* Body: Fully Ground from a single piece for superior concentricity* Cut Direction: Right-Hand Cut* Surface Finish: BrightAttributes: 0.3 mm, Individual, Metal. tradeinn Bricoinn
