Ruko Hss Din 338 Type N Serie 214 15.5mm Drill Set 5 Pieces. RUKO HSS DIN 338 Type N Serie 214 15.5mm Drill SetElevate your drilling projects with the professional-grade RUKO HSS DIN 338 Type N Serie 214 Drill Set. This 15.5 mm set is meticulously engineered for superior performance in metal, plastics, and a variety of other demanding materials, making it an indispensable accessory for any serious workshop or job site.Experience the pinnacle of precision with this high-performance ground standard twist drill, expertly crafted from heavy-duty high-speed steel (HSS). The fully ground manufacturing process ensures each drill bit in the set has a precise concentricity, eliminating bit-wobble and guaranteeing perfectly round, clean, and accurate holes every time. A standout feature is the advanced Shape C split point tip. Thanks to the split point, this drill has good centring properties, preventing the bit from ´walking´ across the workpiece surface upon starting. This design also requires little pressure, allowing for faster, more controlled drilling with significantly less user fatigue.Designed for exceptional versatility, this drill bit set is the primary choice for drilling into tough materials, including steel with a tensile strength up to 900 N/mm², as well as non-ferrous metals like aluminium and brass. Its capabilities extend seamlessly to drilling plastics, making it a go-to solution for fabrication, assembly, and repair tasks. Furthermore, it delivers consistently reliable performance in other applications, such as drilling bronze and cast iron, proving its value across multiple trade environments.Built to rigorous DIN 338 standards, these drill bits ensure dimensional accuracy and compatibility. The standard cylindrical shank allows for universal use in most corded and cordless drill chucks. The right-hand cutting direction, combined with a 20° - 30° spiral angle and a normal groove profile, provides highly efficient chip and swarf evacuation to prevent clogging and reduce heat build-up. The optimized 118° point angle is ideal for general-purpose metal drilling, while the h8 tolerance ensures a precise fit for high-quality results. Whether you are a professional fabricator, an automotive technician, or a dedicated DIY enthusiast, this RUKO drill set delivers the unwavering precision, efficiency, and durability required for your most challenging projects.Technical Specifications:* Diameter: 15.5 mm* Material: High-Speed Steel (HSS)* DIN Standard: 338* Overall Length: 178.0 mm* Spiral Length: 120.0 mm* Drilling Depth: 5 x diameter* Tip Grinding: Shape C: Split point* Point Angle: 118°* Tolerance: h8* Shaft Type: Cylindrical* Cutting Direction: Right-hand cutting* Spiral Angle: 20° - 30°* Groove Profile: Normal* Core: Normal* Net Weight: 166 g. tradeinn Bricoinn
