RUKO 203035 Pack de 10 brocas helicoidales Larga DIN 340, tipo N HSS, fresada rectificada (Ø 3,5 mm)

Ruko Din 340 Long Hss Ground Helical Ø 3.5 Mm Metal Drill Bit 10 Units. RUKO DIN 340 Long HSS Ground Helical Ø 3.5 mm Metal Drill Bit 10 unitsUnlock unparalleled precision and performance for your deep drilling applications with the RUKO DIN 340 Long Series Helical Metal Drill Bit. Expertly engineered for professionals and demanding workshop tasks, this high-performance 3.5 mm drill bit is your solution for creating deep, clean, and accurate holes in a wide variety of metals. Designed to meet the rigorous DIN 340 standard, its extended length makes it perfectly suitable for deep drilling projects where standard bits fall short.Experience a superior drilling process built on a foundation of strength and precision. This individual bit is distinguished by its high resistance to breakage, providing you with a reliable and long-lasting tool that withstands the pressures of repetitive, heavy-duty use. The advanced ground helical flute design ensures optimal chip evacuation, which is critical for maintaining performance and preventing binding during deep hole creation. For best results when tackling deep holes, small, incremental advances of the drill bit combined with regular chip removal are necessary to ensure a smooth and successful operation.The meticulous construction of this metal drill bit guarantees exceptional results. Its conical point grinding and a precise 118º cutting angle allow for excellent self-centering, minimizing bit wander and ensuring your holes start exactly where you intend. The right-hand cut direction and a 20-30º helix angle are optimized for efficient material removal across numerous metallic materials. With a strict h8 diameter tolerance, you can be confident in the dimensional accuracy of every hole you drill. The bright, polished surface not only provides a professional finish but also reduces friction for smoother drilling.Each pack of ten drill bits is conveniently housed in a durable, translucent plastic case with a distinctive blue label, allowing for easy identification and secure storage in your workshop or toolbox.Technical Specifications:* Drill Bit Type: High-performance long series drill bit (DIN 340)* Diameter: 3.5 mm* Point Angle: 118º* Grind Type: Conical point grinding* Helix Angle: 20-30º* Diameter Tolerance: h8* Cutting Direction: Right-hand cut* Surface Finish: BrightPrimary Applications:This versatile drill bit is designed for making deep holes in a vast range of materials, including:* Alloyed and unalloyed steel (up to approx. 900 N/mm² strength)* Cast steel* Gray cast iron* Malleable cast iron* Nodular cast iron* Die-cast iron* Sintered iron* Nickel silver* Graphite cast iron* Short-chipping aluminum alloys* Bronze* Brass. tradeinn Bricoinn
