RUKO DIN 338 HSS Ground Self-Centering Helical Ø 5.6 mm Metal Drill BitUnleash superior precision and efficiency in your workshop with the RUKO DIN 338 HSS Ground Helical Drill Bit, the professional standard for drilling in metal and other demanding materials. Specifically engineered with a 5.6 mm diameter, this high-performance drill bit is designed for all types of drills, delivering consistently excellent results across a wide range of common materials. It is the ultimate accessory for professionals who demand reliability, accuracy, and longevity from their tools.Experience the pinnacle of drilling performance, starting with the advanced self-centering split point. Ground in a conical point shape according to DIN 1412 C, this feature allows for immediate, wander-free starting on smooth or curved surfaces without the need for pre-punching or a center mark. This saves you valuable time and ensures perfect hole placement every single time. The fully ground body of this individual metal drill bit provides exceptionally high concentricity and rotational accuracy, which translates to cleaner, burr-free holes and reduced vibration during operation. The N-type point geometry with its good centering capability requires lower feed pressure, minimizing user fatigue and reducing wear and tear on your electric tool.Engineered for optimal performance, this drill bit features a precise 118° cutting angle combined with a 20-30º spiral angle, a combination that ensures efficient chip removal and smooth drilling action. The bright surface finish reduces friction and material build-up, further enhancing its cutting performance. With a strict diameter tolerance of h8 and a right-hand cut, this bit is built for accuracy. Its robust cylindrical shank also features an h8 tolerance, guaranteeing a secure, slip-free grip and precise clamping in any standard drill chuck. This meticulous construction allows for a professional drilling depth of 5 times the diameter, enabling you to tackle both shallow and deep hole applications in metal and plastics with confidence.The versatility of the RUKO DIN 338 HSS twist drill bit is unmatched. It is expertly designed for a vast range of applications, making it an indispensable tool for any metalworking task. Effortlessly drill through alloyed and unalloyed steel and cast steel (up to a strength of approx. 900 N/mm²), grey cast iron, malleable cast iron, nodular cast iron, die-cast iron, sintered iron, alpaca, graphite cast iron, aluminum alloys, bronze, and brass. This standard high-performance twist drill bit made of high-speed steel HSS is your go-to solution for reliable and precise drilling across the most common industrial and workshop materials. tradeinn Bricoinn
