Ruko Din 338 Turbo Hss Ground Helical Ø 5.1 Mm Metal Drill Bit 10 Units. RUKO DIN 338 TURBO HSS Ground Helical Ø 5.1 mm Metal Drill BitExperience unparalleled performance in metal drilling with the RUKO DIN 338 TURBO HSS Ground Helical Drill Bit. Engineered for professionals and demanding enthusiasts who require speed, precision, and a flawless finish, this 5.1 mm individual drill bit transforms challenging tasks into effortless operations. It is the ultimate solution for high-performance drilling, especially when working with thin metal sheets and profiles where accuracy and a clean cut are paramount.Key Benefits and Superior PerformanceThis high-speed steel (HSS) drill bit is designed to deliver exceptional results across a variety of materials. Its specialized geometry ensures rapid, clean, and precise drilling, significantly reducing work time and improving the quality of your finished product.* Unmatched Speed and Efficiency: The aggressive TURBO tip combined with an extremely steep 56° spiral angle allows for remarkably fast chip evacuation. This design minimizes heat buildup and enables a drilling speed that leaves standard drill bits behind, boosting your productivity on any project.* Exceptional Precision and Clean Finishes: The 130° point angle features a special self-centering split point that bites into the material instantly, preventing drill walking and eliminating the need for a center punch. This ensures pinpoint accuracy from the moment the bit touches the surface. The result is consistently clean, perfectly round holes without burrs, which is critical for manual drilling in thin sheets.* Enhanced Stability and Grip: The innovative three-flat shank (for diameters from 5.0 mm upwards) provides a secure, non-slip grip in any drill chuck. This feature guarantees maximum torque transfer from the drill to the bit, preventing slippage under high load and ensuring stable, controlled drilling even in tough materials.Technical Specifications* Product Type: Helical Drill Bit* Diameter: 5.1 mm* Standard: DIN 338* Point Angle: 130° with Self-Centering Split Point* Spiral Angle: 56° (TURBO Design)* Tolerance: h8* Cut Direction: Right-Hand Cut* Shank Design: Three-Flat Shank* Primary Application: Metal, specifically for thin sheets and profiles up to 5.0 mm.* Secondary Applications: Alloyed and Unalloyed Cast Steel (up to 900 N/mm²), Wood, and Plastic.* Drilling Type: Ideal for manual drilling applications requiring burr-free, clean holes. tradeinn Bricoinn
