RUKO 2140825 - Pack de 10 brocas helicoidales DIN 338, tipo N HSS, fresada-rectificada, con autocentrado (Ø 8,25 mm)

Ruko Din 338 Hss Ground Self-centering Helical Ø 8.25 Mm Metal Drill Bit 10 Units Clear . RUKO DIN 338 HSS Ground Metal Drill Bit | 8.25 mm Self-CenteringAchieve unparalleled precision and efficiency in your metalworking projects with the RUKO DIN 338 HSS Ground Helical Drill Bit. Expertly engineered for professionals and serious enthusiasts, this 8.25 mm metal drill bit delivers consistent, high-quality performance across a wide array of materials. As a leading product in electric tool accessories, it embodies the reliability and accuracy required for demanding drilling tasks. High-Performance Drilling for ProfessionalsEngineered as a standard high-performance twist drill bit, this tool is your reliable solution for all types of drills, delivering exceptional results in common materials. The entire body is fully ground from a single piece of high-speed steel (HSS), a process that guarantees superior concentricity and rotational precision. This meticulous manufacturing minimizes bit wander and ensures that every hole is perfectly round and accurately placed, elevating the quality of your finished work. Its robust construction is designed to handle the rigors of professional use, providing a drilling depth of up to 5 times its diameter for substantial work on both metal and plastics. Advanced Design for Superior FunctionalityThe standout feature of this RUKO drill bit is its advanced point geometry. It features a conical point grinding with a split point, meticulously crafted according to DIN 1412 C. This self-centering tip is a game-changer, preventing the bit from ´walking´ across the workpiece surface. It allows for an immediate and precise start without the need for a center punch, saving you valuable time and eliminating the risk of misplaced holes.With a standard 118° cutting angle and a Type N spiral angle of 20-30º, the bit provides an optimal balance between aggressive cutting and efficient chip evacuation. The right-hand cut design ensures smooth material removal, reducing feed pressure and user fatigue. The cylindrical shank is manufactured with a precise h8 tolerance, ensuring a secure, slip-free grip in any standard drill chuck, which further enhances stability and accuracy during operation. Unmatched Versatility Across MaterialsThis 8.25 mm individual metal drill bit demonstrates its remarkable versatility across an extensive range of applications. It is expertly designed for drilling into alloyed and unalloyed steel and cast steel with a tensile strength up to approximately 900 N/mm². Furthermore, it excels when working with grey cast iron, malleable cast iron, nodular cast iron, die-cast iron, sintered iron, nickel silver, and graphite cast iron. Its capabilities also extend to softer non-ferrous metals, providing clean, burr-free holes in aluminum alloys, bronze, and brass. The bright surface finish reduces friction and aids in chip flow, making it a truly universal tool for your workshop.---Technical Specifications:* Diameter: 8.25 mm* Drill Type: Metal* Standard: DIN 338* Point Geometry: Conical Point with Split Point (DIN 1412 C)* Point Angle: 118°* Spiral Angle: 20-30° (Type N)* Diameter Tolerance: h8* Shank: Cylindrical* Cut Direction: Right-hand* Surface: Bright* Package Type: Individual Unit. tradeinn Bricoinn
