RUKO 203030 - Pack de 10 brocas helicoidales Larga DIN 340, tipo N HSS, fresada-rectificada (Ø 3 mm)

Ruko Din 340 Long Hss Ground Helical Ø 3 Mm Metal Drill Bit 10 Units. RUKO DIN 340 Long HSS Ground Metal Drill Bit Ø 3 mm - For Precision Deep Hole DrillingAchieve unparalleled precision and extended reach in your most demanding metalworking projects with the RUKO DIN 340 Long Series HSS Ground Helical Metal Drill Bit. Engineered in Germany for professionals and serious enthusiasts, this high-performance long series drill bit is the definitive solution for tasks requiring deep hole drilling where standard-length bits fall short. Its robust design and superior geometry make it an essential accessory for any electric tool collection, delivering consistent, reliable results every time.Exceptional Performance and DurabilityExperience the pinnacle of drilling efficiency. This 3 mm drill bit is designed with a high resistance to breakage, providing you with the confidence to tackle challenging materials without fear of tool failure. The fully ground High-Speed Steel (HSS) construction ensures a sharper, more precise cutting edge and a longer service life compared to conventional rolled bits. Each individual bit is crafted for maximum performance, allowing you to work faster and more accurately. The bright surface finish not only provides a clean aesthetic but also reduces friction and material buildup, contributing to smoother operation and cleaner holes.Engineered for Deep and Accurate BoresThe primary benefit of the DIN 340 standard is its extended length, making it perfectly suitable for deep hole drilling applications in a variety of metals. To achieve the best results when creating deep holes, it is recommended that small advances of the drill bit are made, with frequent retraction for proper chip removal. This technique prevents clogging and overheating, ensuring the integrity of both the workpiece and the bit. Its industrial-quality construction guarantees stability and precision, even at extended depths.Key features include:* Conical Point Grinding: The expertly shaped tip with a 118º cutting angle allows for excellent self-centering upon starting a hole, minimizing walking and eliminating the need for pre-punching on many surfaces.* Optimized Helix Angle: A specialized 20-30º helix angle facilitates highly efficient chip evacuation, which is critical for preventing jams and maintaining a consistent cutting speed during deep drilling.* Precision Tolerance: Manufactured to a strict h8 diameter tolerance, this drill bit produces accurately sized holes, perfect for applications requiring tight fits for pins, bolts, or taps.Unmatched Versatility Across a Wide Range of MaterialsThis is the ultimate individual drill bit for a vast array of metal applications. Its robust geometry and premium construction make it ideal for working with:* Alloyed and unalloyed steel (up to a tensile strength of approx. 900 N/mm²)* Cast steel, gray cast iron, malleable cast iron, and nodular cast iron* Die-cast iron and sintered (powdered) iron* Nickel silver and graphite cast iron* Short-chipping aluminum alloys* Bronze and brassEach set is presented in a practical, translucent plastic case with a distinctive blue label, ensuring your bits are protected, organized, and easy to identify.Technical Specifications:* Standard: DIN 340* Type: Long HSS Ground Helical* Diameter (Ø): 3 mm* Primary Application: Metal* Point Angle: 118º* Helix Angle: 20-30º* Diameter Tolerance: h8* Cutting Direction: Right-hand cut* Surface: Bright, ground finish. tradeinn Bricoinn
