RUKO 2146055 Pack de 10 brocas helicoidales Turbo DIN 338 HSS, fresada rectificada (Ø 5,5 mm)

Ruko Din 338 Turbo Hss Ground Helical Ø 5.5 Mm Metal Drill Bit 10 Units. RUKO DIN 338 TURBO HSS Ground Helical Ø 5.5 mm Metal Drill BitExperience the pinnacle of drilling performance with the RUKO DIN 338 TURBO HSS Ground Helical Metal Drill Bit. Engineered in Germany for professionals and demanding enthusiasts, this 5.5 mm drill bit is specifically designed to deliver unparalleled precision, speed, and cleanliness, especially when working with thin metal sheets and profiles. Forget wandering starts and messy results, the TURBO design redefines what´s possible with a standard electric drill. Unmatched Performance on Thin MaterialsThe standout feature of this individual drill bit is its extraordinary capability for drilling thin sheets and profiles up to 5.0 mm thick. Its specialized TURBO tip geometry is self-centering, allowing for immediate, precise starts on smooth or curved surfaces without the need for a center punch. This eliminates bit ´walking´ and ensures your holes are exactly where you intend them to be. The design is optimized for manual drilling in thin-gauge metal, providing the control and stability needed for delicate work. Exceptionally Clean, Burr-Free HolesAchieve a finish that requires minimal to no rework. Thanks to its advanced cutting angles and fully ground construction, this bit shears through metal cleanly, producing perfectly round holes with virtually no burrs on the entry or exit side. This saves you valuable time and effort on post-drilling deburring and finishing, leading to a more efficient workflow and a superior quality end product. It is the ideal choice for applications where a clean, professional finish is paramount. Versatile and Robust ApplicationWhile its specialty is metal, this drill bit's versatility makes it an indispensable tool for any workshop. It excels in drilling both alloyed and unalloyed cast steel with a tensile strength up to 900 N/mm², making it a reliable workhorse for a wide range of metalworking projects. Furthermore, its sharp, precision-ground edges perform exceptionally well on other materials, including wood and various plastics, providing clean and accurate holes across multiple applications. The three-flat shank, featured on this 5.5 mm diameter bit, guarantees a secure, non-slip grip in your drill chuck. This ensures maximum torque transfer for efficient drilling and prevents the bit from spinning under heavy load, enhancing both safety and performance.
