Ruko Din 338 Hss Ground Self-centering Helical Ø 8.5 Mm Metal Drill Bit 10 Units. RUKO DIN 338 HSS Ground Self-Centering Metal Drill Bit - 8.5 mmCategory: Electric tool accessoriesSubcategory: Drill bits---Achieve superior precision and efficiency in your metalworking projects with the RUKO DIN 338 HSS Ground Self-Centering Helical Drill Bit. Engineered for professionals and demanding DIY enthusiasts, this 8.5 mm individual metal drill bit delivers exceptional, high-performance results across a wide spectrum of common materials. Its advanced design and robust construction make it an indispensable accessory for all types of drills, ensuring clean, accurate holes with every use.The standout feature of this drill bit is its self-centering split point, designed according to DIN 1412 C. This specialized conical point grind allows the bit to engage the material instantly without wandering or walking, eliminating the need for pre-punching or a pilot hole. This saves valuable time and guarantees perfect hole placement from the very first rotation, even on curved or smooth surfaces.Crafted from high-performance HSS high-speed steel, the entire body of the drill bit is fully ground. This meticulous manufacturing process results in high concentricity and outstanding rotational precision, significantly reducing vibration and ensuring a flawlessly round, burr-free hole. The bright surface finish and optimized N-type flute geometry provide excellent chip evacuation, reducing heat buildup and requiring lower feed pressure from the user. This not only enhances cutting speed but also reduces operator fatigue and prolongs the life of both the drill bit and the power tool.Key Advantages for Uncompromised Performance:* Effortless, Wander-Free Starts: The self-centering split point (DIN 1412 C) provides immediate grip on the workpiece, ensuring pinpoint accuracy without the need for center punching.* Unmatched Precision: The fully ground body guarantees high concentricity and rotational stability, delivering exceptionally clean and precise holes.* High-Efficiency Drilling: An optimized N-type point and 20-30º spiral angle allow for faster cutting with lower feed pressure, improving productivity and reducing wear.* Professional Durability: Designed for a drilling depth of up to 5 times its diameter, this drill bit is built for demanding professional work in both metal and plastics.Broad Application Range:This versatile 8.5 mm metal drill bit is the ideal choice for a multitude of applications. It is perfectly suitable for drilling in: alloyed and unalloyed steel and cast steel (up to a strength of approximately 900 N/mm²), gray cast iron, malleable cast iron, nodular cast iron, die-cast iron, sintered iron, nickel silver, graphite cast iron, various aluminum alloys, bronze, and brass.Technical Specifications:* Diameter (Ø): 8.5 mm* Standard: DIN 338* Point Angle: 118°* Spiral Angle: 20-30º* Diameter Tolerance: h8* Shank: Cylindrical with h8 tolerance for precise clamping* Cut Direction: Right-hand cut* Surface Finish: Bright* Primary Attribute: Individual, high-performance drill bit for metal. tradeinn Bricoinn
