Ruko Din 338 Turbo Hss Ground Helical Ø 7 Mm Metal Drill Bit 10 Units. RUKO DIN 338 TURBO HSS Ground Helical Ø 7 mm Metal Drill BitExperience unparalleled precision and speed with the RUKO DIN 338 TURBO HSS Ground Helical Metal Drill Bit. Engineered for professionals and discerning craftspeople, this 7 mm drill bit sets a new standard for performance, especially for drilling thin sheets and profiles. Its innovative design eliminates the need for pre-punching or pilot drilling, allowing you to work faster and more efficiently while achieving exceptionally clean results. This high-performance individual bit is your ultimate solution for demanding metalworking applications.The standout feature of this drill bit is its advanced TURBO tip, which provides immediate self-centering upon contact with the workpiece. This unique geometry ensures the bit starts drilling exactly where you place it, preventing wandering and guaranteeing precise hole placement every time. Combined with a sharp 130° cutting angle, it slices through material with minimal effort, producing clean holes without burrs. This makes it the perfect tool for manual drilling in thin sheets, where a clean entry and exit are critical for a professional finish.Engineered for optimal performance, the bit features a specialized 56° helix angle that facilitates rapid and efficient chip evacuation. This prevents clogging and overheating, extending the tool´s life and maintaining a consistent cutting speed. The fully ground HSS body ensures superior concentricity and dimensional accuracy, adhering to a strict h8 tolerance for perfectly sized holes. For enhanced grip and maximum torque transfer, this drill bit incorporates a three-flat shank, a critical design element that prevents slippage in the drill chuck under high load, ensuring all the power from your tool is delivered directly to the cutting edge.While it is especially for drilling thin sheets and profiles up to 5.0 mm, its versatility is remarkable. This drill bit is highly effective on a wide range of materials. It effortlessly drills through alloyed and unalloyed cast steel with a tensile strength of up to 900 N/mm². Furthermore, its sharp, precise design also makes it a reliable choice for drilling in wood and plastic, making it a valuable and versatile addition to any toolkit.Technical Specifications:* Product Type: Ground Helical Drill Bit* Standard: DIN 338* Diameter: 7 mm* Primary Material Application: Metal* Format: Individual* Cutting Direction: Right-hand cut* Point Angle: 130°* Helix Angle: 56°* Diameter Tolerance: h8* Shank Design: Three-flat shank* Recommended Use: Especially for drilling thin sheets and profiles, Alloyed and unalloyed cast steel (up to 900 N/mm²), Wood, Plastic. tradeinn Bricoinn
