Ruko Din 338 Hss Ground Self-centering Helical Ø 3.25 Mm Metal Drill Bit 10 Units. Category: Electric tool accessoriesSubcategory: Drill bits RUKO DIN 338 HSS Ground Self-Centering Helical Ø 3.25 mm Metal Drill Bit 10 unitsExperience unparalleled precision and industrial-grade performance with the RUKO DIN 338 HSS Ground Metal Drill Bit. Engineered in Germany for professionals and discerning craftspeople, this individual 3.25 mm drill bit is the definitive solution for high-accuracy drilling in a vast range of common materials. Its advanced, fully ground construction ensures superior rotational accuracy and concentricity, delivering clean, perfectly round holes with every use. This makes it an essential and reliable accessory for all types of drills, from handheld power tools to stationary drill presses.Designed for efficiency and ease of use, this high-performance drill bit eliminates the common frustrations of metalworking. The conical point grinding, featuring a split point according to DIN 1412 C, provides immediate and aggressive self-centering action. This key benefit prevents the bit from walking on the material surface and completely removes the need for pre-drilling or center punching, saving you valuable time and guaranteeing pinpoint accuracy from the very start. The optimized N-form point further enhances this by requiring significantly lower feed pressure, reducing user fatigue and making the drilling process smoother and more controlled.Key Benefits & Features:* Effortless & Precise Starts: The split point design ensures immediate, aggressive self-centering upon contact with the workpiece, preventing bit wander and eliminating the need for a center punch.* Superior Rotational Accuracy: A fully ground HSS body guarantees exceptional concentricity and rotational accuracy, resulting in flawlessly clean and precisely sized holes.* High-Performance Efficiency: Built as a standard high-performance twist drill bit, it delivers consistent, reliable results with a lower feed pressure requirement, increasing productivity and reducing tool wear.* Professional Deep Drilling: Engineered for professional applications on metal and plastics, it is capable of achieving a drilling depth of 5 times its diameter.* Secure & Precise Clamping: The cylindrical shank is manufactured with a tight h8 tolerance, ensuring a secure and precise fit in the drill chuck for maximum stability and power transfer.· High-performance drill bit, suitable for all types of drills in common materials.· High concentricity and rotational accuracy.· Conical point grinding with split point according to DIN 1412 C.· Cutting angle: 118°· Spiral angle: 20-30º· Ø-tolerance: h8· Bright surface.· Right-hand cut.Versatile Applications:This robust drill bit is expertly engineered for exceptional performance across a wide spectrum of materials, including:· Alloyed and unalloyed steel and cast steel (up to a tensile strength of approx. 900 N/mm²)· Gray cast iron, malleable cast iron, nodular cast iron, die-cast iron· Sintered iron· German silver· Graphite cast iron· Aluminum alloys, bronze, and brassChoose the RUKO DIN 338 HSS Ground Metal Drill Bit for your workshop and elevate your projects with the precision, reliability, and performance that defines professional-grade tooling. tradeinn Bricoinn
