RUKO DIN 338 HSS Ground Self-Centering Helical Metal Drill Bit Ø 9.75 mm - 10 unitsCategory: Electric tool accessoriesSubcategory: Drill bits---Achieve unparalleled precision and efficiency in your metalworking projects with the RUKO DIN 338 HSS Ground Helical Drill Bit. Engineered for professionals and discerning craftsmen, this 9.75 mm drill bit is the ultimate solution for creating clean, accurate holes in a wide range of common materials. Its high-performance design ensures superior results, whether you are working in a busy workshop or on a demanding job site. This individual bit is expertly crafted for high-performance drilling in metal, delivering reliability when it matters most.Experience the superior difference of a fully ground HSS high-speed steel body. This meticulous manufacturing process provides exceptional concentricity and rotational accuracy, guaranteeing a smooth, stable drilling experience that minimizes vibration and maximizes the quality of every hole. The result is a perfect, clean-cut finish that meets the highest professional standards.The advanced self-centering split point, designed according to DIN 1412 C, is a game-changer for productivity. It bites into the material instantly upon contact, eliminating the frustrating walking or wandering typical of standard drill bits. This feature ensures your holes are precisely where you want them, saving you valuable time and preventing costly material damage by removing the need for pre-punching or a pilot hole. The point geometry also requires significantly lower feed pressure, reducing user fatigue and strain on your power tool during extended use.With a cylindrical shank featuring a tight h8 tolerance, this drill bit ensures precise and secure clamping in any standard drill chuck. This firm grip prevents slippage and enhances the overall stability and accuracy of the drilling process. The bright surface finish and optimized flute geometry contribute to excellent chip evacuation, keeping the cutting area clear and reducing heat build-up for a longer tool life and consistent performance.
