RUKO 203055 - Pack de 10 brocas helicoidales Larga DIN 340, tipo N HSS, fresada-rectificada (Ø 5,5 mm)

Ruko Din 340 Long Hss Ground Helical Ø 5.5 Mm Metal Drill Bit 10 Units. RUKO DIN 340 Long HSS Ground Helical Metal Drill Bit - 5.5 mmExperience unparalleled precision and endurance for your most demanding deep drilling tasks with the RUKO DIN 340 Long Series Helical Drill Bit. Expertly engineered for professional use in electric tool accessories, this 5.5 mm ground HSS drill bit is the ultimate solution for creating clean, accurate holes in a wide variety of metals. Whether you are a fabricator, mechanic, or serious DIY enthusiast, this drill bit delivers the performance and reliability that complex projects demand.High-Performance for Deep DrillingSpecifically designed as a high-performance long series drill bit, this tool excels in applications requiring significant drilling depth. Its extended length allows you to reach and bore through thicker materials with confidence and stability. It is perfectly suitable for deep drilling where standard-length bits fall short, making it an indispensable individual tool for challenging metalworking and construction jobs.Exceptional Durability and Breakage ResistanceBuilt to withstand the rigors of professional environments, this drill bit boasts an exceptionally high resistance to breakage. Its robust construction ensures a longer service life and reliable performance, even when working with tough materials. This enhanced durability minimizes downtime and replacement costs, providing a superior return on investment and consistent results you can count on, hole after hole.Engineered for Precision and EfficiencyEvery feature of this drill bit is optimized for superior performance on metal.* Optimized Flute Design: A spiral angle of 20-30° combined with a standard right-hand cut facilitates efficient chip evacuation. This is crucial for preventing overheating and maintaining a smooth, uninterrupted drilling process, especially in deep holes.* Superior Accuracy: Manufactured to a strict Ø-tolerance of h8, this 5.5 mm drill bit guarantees dimensionally accurate holes. This level of precision is critical for applications involving fasteners, taps, or press-fits where exact dimensions are non-negotiable.* Bright Surface Finish: The bright, ground surface reduces friction and prevents material build-up on the bit, contributing to a cleaner cut, smoother operation, and extended tool life.Unmatched Versatility for Metal ApplicationsThis high-performance drill bit is engineered to work flawlessly across a comprehensive range of materials. Its versatile design makes it the go-to choice for:* Alloyed and unalloyed steel and cast steel (up to a tensile strength of approx. 900 N/mm²)* Gray cast iron, malleable cast iron, and nodular cast iron* Die-cast iron and sintered iron* Nickel silver and graphite cast iron* Aluminum alloys, bronze, and brassGuidance for Optimal Deep Hole DrillingFor optimal results and to maximize the tool´s lifespan when performing deep drilling, a specific technique is essential. It is highly recommended to use small, consistent feed rates and to periodically retract the bit for efficient chip removal (peck drilling). This professional method prevents the flutes from clogging, reduces heat build-up, and ensures a straight, clean hole from start to finish.The drill bits are supplied in a durable, translucent plastic case with a distinctive blue RUKO label, ensuring safe storage, easy identification, and protection from damage. tradeinn Bricoinn
