RUKO 214068 - Pack de 10 brocas helicoidales DIN 338, tipo N HSS, fresada-rectificada, con autocentrado (Ø 6,8 mm)

Ruko Din 338 Hss Ground Self-centering Helical Ø 6.8 Mm Metal Drill Bit 10 Units. RUKO DIN 338 HSS Ground Metal Drill Bits (6.8mm, 10-pack) offer superior precision for metalworking. Featuring self-centering split-point technology, they eliminate walking and pre-punching, ensuring perfectly centered holes with clean finishes. The ground HSS body guarantees high concentricity and accuracy. Ideal for all drill types, these bits require lower feed pressure, reducing fatigue and tool wear. Optimized spiral angles ensure efficient chip evacuation, preventing overheating for consistent performance. Versatile for alloyed/unalloyed steel, cast iron, aluminum, and non-ferrous metals, they offer a drilling depth of up to 5xD. RUKO DIN 338 HSS Ground Self-Centering Helical Ø 6.8 mm Metal Drill BitAchieve unparalleled precision and efficiency in your metalworking projects with the RUKO DIN 338 HSS Ground Metal Drill Bit. Designed for professionals and demanding applications, this high-performance 6.8 mm drill bit delivers exceptional performance and reliability across a wide range of common materials. It stands as a testament to superior engineering, ensuring every hole is drilled with maximum accuracy and a clean finish, making it an essential accessory for any electric tool kit. Superior Precision and Self-Centering ActionExperience flawless starts and perfectly centered holes with every use. This drill bit features a conical point grinding with a split point, meticulously crafted according to DIN 1412 C standards. This advanced self-centering tip eliminates the common issue of the bit walking on the material surface, removing the need for pre-punching or pilot drilling. The fully ground HSS body guarantees outstanding concentricity and high rotational accuracy, translating to cleaner, more precise holes and reducing vibrations for smoother operation. High-Performance Drilling and EfficiencyEngineered as a standard high-performance twist drill bit, this tool is suitable for all types of drills, from handheld models to stationary drill presses. Its N-type point geometry ensures excellent centering while requiring significantly lower feed pressure, which reduces user fatigue and minimizes wear on your power tool. The optimized 20-30º spiral angle provides efficient chip evacuation, preventing clogging and overheating to maintain consistent cutting performance even during prolonged use. The sharp 118° cutting angle is ideal for general-purpose drilling in a variety of metals. Unmatched Versatility for Metal and MoreTackle a vast array of demanding materials with confidence. This single, individual drill bit is your go-to solution for professional work on metal and plastics.
