RUKO 228022 - Pack de 10 brocas helicoidales DIN 338 tipo UNI, HSSE-Co 5 (Ø 2.2 mm)

Ruko Din 338 Uni Hsse-co 5 Helical Ø 2.2 Mm Metal Drill Bit 10 Units. RUKO DIN 338 UNI HSSE-Co 5 Metal Drill Bit | 2.2 mmExperience a new level of precision and efficiency in metal drilling with the RUKO DIN 338 UNI HSSE-Co 5 Helical Twist Drill Bit. This high-performance 2.2 mm bit has been specially developed to unlock the full potential of portable cordless drills and screwdrivers, delivering its best performance in materials up to 5.0 mm thick. It is the ultimate accessory for professionals and demanding enthusiasts who require accuracy, speed, and durability on the job.The design of this drill bit is centered around superior performance in manual applications. A key innovation is the 3-flat shank, which allows for an exceptionally secure and excellent chuck grip with minimal tightening force required. This revolutionary design ensures optimal power transmission from your cordless tool directly to the cutting edge, preventing the bit from slipping in the chuck during high-torque operations. It is not even necessary to screw the drill in all the way, saving you time and effort on every change.Achieve flawless and accurate starts every time thanks to the precision-ground 135° split point. This advanced tip geometry provides high centering accuracy, eliminating the frustrating walking or wandering common with standard drill bits. This feature is especially beneficial in manual applications, allowing you to start holes with confidence and precision without the need for a center punch. The split point is engineered to prevent slipping when drilling on curved surfaces, such as pipes or rounded stock, ensuring a clean and precise entry point.Engineered for maximum efficiency, this drill bit helps you work longer and faster. The design significantly reduces the required cutting force, which translates directly to increased battery life for your cordless tools. Furthermore, the specialized black coating is a critical feature that dramatically increases wear resistance, protecting the bit from the rigors of frequent use. This coating also effectively prevents cold welding and the formation of built-up edges, ensuring a smoother cutting action and a longer tool lifespan.Performance is further enhanced by the aggressive 40° clearance angle, a feature designed for perfect and rapid chip removal. This efficient evacuation of material prevents clogging and overheating, allowing you to maintain high cutting speeds with remarkable stability and precision. The result is a cleaner hole, a faster work rate, and a drill bit that consistently performs at the highest level.
