RUKO 2140525 - Pack de 10 brocas helicoidales DIN 338, tipo N HSS, fresada-rectificada, con autocentrado (Ø 5,25 mm)

Ruko Din 338 Hss Ground Self-centering Helical Ø 5.25 Mm Metal Drill Bit 10 Units. RUKO DIN 338 HSS Ground Metal Drill Bit Ø 5.25 mm | Precision & PerformanceElevate your professional drilling projects with the RUKO DIN 338 HSS Ground Helical Drill Bit, engineered for superior performance and exceptional accuracy in a variety of common materials. This high-performance 5.25 mm drill bit is the definitive choice for professionals and craftsmen who demand reliability, precision, and efficiency for every task involving Metal drilling. Designed for use with all types of drills, it delivers consistent, high-quality results job after job.Experience the difference that true German engineering makes. Each Individual bit is crafted to provide outstanding concentricity and rotational precision, eliminating wobble and ensuring perfectly clean, round holes. This level of accuracy is crucial for applications where tolerance and finish are paramount.Key Features & Benefits:* Effortless & Accurate Starts: Featuring a split point ground to DIN 1412 C specifications, this drill bit is self-centering. This advanced geometry prevents the bit from walking or wandering on smooth or curved surfaces, allowing you to start drilling immediately and precisely without the need for a center punch. This feature also significantly reduces the feed pressure required, minimizing user fatigue and improving control.* Unmatched Precision: The entire body of the drill bit is fully ground from a solid piece of high-speed steel. This meticulous manufacturing process guarantees exceptional concentricity and a straight, true tool, resulting in dimensionally accurate holes and a superior surface finish within the bore.* Optimized for Performance: Engineered with a standard N-type point and a 20-30º spiral angle, this bit ensures excellent chip evacuation. The right-hand cut efficiently clears away debris and swarf from the drilling area, preventing clogging, reducing heat buildup, and allowing for faster, uninterrupted drilling.* Professional-Grade Design: With a drilling depth capacity of 5 times its diameter, this bit is built for professional work in metal and plastics. The cylindrical shank, manufactured to a tight h8 tolerance, ensures secure and precise clamping in any standard drill chuck, maximizing power transfer and stability during operation.Technical Specifications:* Diameter (Ø): 5.25 mm* Standard: DIN 338* Point Geometry: Split Point Form C (according to DIN 1412 C)* Point Angle: 118°* Spiral Angle: 20-30º* Diameter Tolerance: h8* Shank: Cylindrical with h8 tolerance* Drilling Direction: Right-hand cut* Surface: Bright Finish* Drilling Depth: Up to 5 x diameter. tradeinn Bricoinn
