Ruko Din 338 Hss Ground Self-centering Helical Ø 4.2 Mm Metal Drill Bit 10 Units Clear . RUKO DIN 338 HSS Metal Drill Bits offer unmatched precision for your metalworking. These 4.2mm drill bits feature a self-centering split point design, eliminating the need for pre-marking and ensuring perfect hole placement without walking. Made from fully ground high-speed steel, they deliver high concentricity, smooth operation, and clean cuts. Optimized for metal, their N-form point reduces feed pressure for less fatigue. This 10-unit pack is ideal for alloyed/unalloyed steel, cast iron, and various non-ferrous metals. RUKO DIN 338 HSS Ground Self-Centering Helical Ø 4.2 mm Metal Drill BitAchieve unparalleled precision and efficiency in your metalworking projects with the RUKO DIN 338 HSS Ground Metal Drill Bit. Engineered for professionals and demanding enthusiasts, this high-performance 4.2 mm drill bit is the ultimate solution for drilling in a wide array of common materials, delivering clean, accurate holes with every use. Its robust construction and intelligent design make it an indispensable accessory for all types of drills, ensuring reliability and superior results.The standout benefit of this drill bit lies in its self-centering capability. Featuring a ground-in cone point shape with a split point according to DIN 1412 C, it eliminates the need for pre-punching or center marking. The bit engages the material immediately without walking, saving you time and guaranteeing perfect hole placement from the start. This high concentricity and rotational accuracy are further enhanced by the fully ground HSS high-speed steel body, which ensures smooth, low-vibration operation and exceptionally clean-cut edges.Designed for versatility and power, this Individual drill bit is optimized for Metal applications. The N-form point geometry provides excellent centering while requiring reduced feed pressure, minimizing user fatigue and extending the life of both the bit and your power tool. The bright, right-hand cut finish and a precise 20-30º spiral angle facilitate efficient chip removal, preventing clogging and overheating during intensive use. With a drilling depth of up to 5 times its diameter, it is perfectly suited for professional work in both metal and plastics, offering the depth and performance required for substantial tasks.· High-performance drill bit, suitable for all types of drills in common materials.· High concentricity and rotational accuracy.· Ground in cone point shape with split point according to DIN 1412 C.· Cutting angle: 118°· Spiral angle: 20-30º· Ø-tolerance: h8· Bright surface.· Right-hand cut.· Applications: for alloyed and unalloyed steel and cast steel (up to a tensile strength of approx. 900 N/mm²), grey cast iron, malleable cast iron, nodular cast iron, die-cast iron, sintered iron, nickel silver, graphite cast iron, aluminum alloys, bronze, and brass.· High-performance standard twist drill bit made of HSS high-speed steel.· Fully ground body for precise concentricity.· N-form point with good centering and reduced feed pressure.· Cylindrical shank with h8 tolerance for precise clamping.· Drilling depth of 5 x diameter for professional work in metal and plastics. tradeinn Bricoinn
