Ruko Din 338 Hss Ground Self-centering Helical Ø 7.75 Mm Metal Drill Bit 10 Units. RUKO DIN 338 HSS Ground Self-Centering Helical Ø 7.75 mm Metal Drill BitExperience unparalleled precision and efficiency in your metalworking projects with the RUKO DIN 338 HSS Ground Metal Drill Bit. Engineered for professionals and discerning enthusiasts, this high-performance 7.75 mm helical drill bit is the ultimate solution for drilling a wide range of common materials with exceptional accuracy and ease. It is the high-performance standard twist drill bit, suitable for all types of drills, designed to deliver consistent and reliable results in demanding environments.Unmatched Precision and Self-Centering ActionForget wandering starts and inaccurate holes. This drill bit features a conical point grinding with an advanced split point according to DIN 1412 C. This N-shaped point geometry provides outstanding self-centering capabilities, eliminating the need for pre-punching on most surfaces and ensuring immediate, precise penetration. This design significantly reduces the required feed pressure, allowing for cleaner, faster, and more controlled drilling. The fully ground body of the drill bit guarantees high concentricity and rotational accuracy, minimizing wobble and producing perfectly round, high-quality holes every time.Superior Performance and Broad Application VersatilityCrafted from premium High-Speed Steel (HSS), each individual drill bit is built for durability and extended tool life. Its robust construction makes it the go-to choice for a vast array of metal drilling tasks. The bright surface finish and an optimized spiral angle of 20-30º facilitate smooth, efficient chip removal, preventing clogging and reducing heat buildup for sustained performance.This versatile drill bit is perfectly suited for a wide range of applications, including:* Alloyed and unalloyed steel and cast steel (up to a strength of approx. 900 N/mm²)* Gray cast iron, malleable cast iron, and nodular cast iron* Die-cast iron and sintered iron* Nickel silver and graphite cast iron* Aluminum alloys, bronze, and brassProfessional-Grade EngineeringDesigned to meet rigorous industrial standards, this 7.75 mm drill bit delivers consistent, professional results. The cylindrical shank is manufactured with a precise h8 diameter tolerance, ensuring a secure, slip-free grip and accurate clamping in all standard drill chucks. With an effective drilling depth of up to 5 times its diameter, it provides the capacity needed for substantial and professional work in both metal and various plastics, making it an indispensable tool for any workshop.Technical Specifications:* Diameter: 7.75 mm* Standard: DIN 338* Point Type: Split Point, Form C (DIN 1412 C)* Point Angle: 118°* Spiral Angle: 20-30°* Diameter Tolerance: h8* Surface: Bright* Material Application: Metal* Drill Bit Type: Individual, Helical Twist* Cut Direction: Right-hand cut. tradeinn Bricoinn
