Ruko Din 340 Long Hss Ground Helical Ø 3.1 Mm Metal Drill Bit 10 Units. RUKO DIN 340 Long HSS Ground Helical Ø 3.1 mm Metal Drill BitUnlock unparalleled precision and performance in your metalworking projects with the RUKO DIN 340 Long Helical Drill Bit, expertly engineered for demanding applications. This high-performance long series drill bit, with a specific diameter of 3.1 mm, is the quintessential accessory for professionals and craftsmen who require accuracy and durability when working with metal. Its extended length makes it perfectly suitable for deep hole drilling, allowing you to access hard-to-reach areas and execute complex tasks with confidence and ease.Engineered for superior endurance, this drill bit boasts an exceptionally high resistance to breakage. This robust construction ensures a longer tool life, even under the rigorous conditions of drilling into tough materials, providing a reliable and cost-effective solution for your workshop. Each individual bit is crafted to maintain its integrity, ensuring consistent performance from the first hole to the last. For optimal results when making deep holes, small, incremental advances of the drill bit paired with frequent chip removal are necessary to ensure a clean cut and prevent overheating.The geometry of this drill bit is meticulously designed for efficiency. It features a precise conical point grinding and a standard 118º cutting angle, a combination that guarantees excellent self-centering upon starting the drill and facilitates a swift, aggressive cut. This design minimizes walking and ensures the hole is exactly where you intend it to be. The optimal spiral angle of 20-30º, paired with a classic right-hand cut, promotes highly effective chip evacuation. This prevents clogging, reduces friction and heat buildup, and ultimately results in a cleaner, smoother, and more accurate finished hole. The bright surface finish further aids in reducing friction for flawless operation.Versatile Applications Across a Range of MetalsThis drill bit is a true workhorse, demonstrating exceptional versatility across a vast spectrum of materials.
