RUKO 214095 Pack de 10 brocas helicoidales DIN 338, tipo N HSS, fresada rectificada, con autocentrado (Ø 9,5 mm)

Ruko Din 338 Hss Ground Self-centering Helical Ø 9.5 Mm Metal Drill Bit 10 Units. RUKO DIN 338 HSS Ground Self-Centering Helical Metal Drill Bit - Ø 9.5 mmAchieve unparalleled precision and efficiency in your metalworking projects with the RUKO DIN 338 HSS Ground Helical Metal Drill Bit. Engineered for professionals and demanding enthusiasts, this high-performance 9.5 mm drill bit is the definitive choice for drilling in a vast array of common materials, delivering consistent, high-quality results every time. Its design is optimized for use with all types of drills, making it a versatile and indispensable accessory for any workshop.Superior Performance and Unmatched PrecisionExperience the difference of a tool crafted for excellence. This standard high-performance twist drill bit is manufactured from premium HSS high-speed steel, ensuring exceptional durability and a long service life even under rigorous use. The entire body is fully ground, a meticulous process that guarantees outstanding concentricity and rotational precision. This results in perfectly clean, round holes with minimal deviation, meeting the tightest tolerances required for professional work. The cylindrical shank, manufactured to a precise Ø-tolerance of h8, ensures secure and accurate clamping in the drill chuck, eliminating wobble and enhancing overall stability during operation.Innovative Self-Centering DesignSay goodbye to frustrating walking and the need for a center punch. The drill bit features a point ground into a conical shape with a split point according to DIN 1412 C. This advanced self-centering tip bites into the material immediately upon contact, providing an accurate start without slipping. Combined with a standard 118° cutting angle, this feature significantly reduces the required feed pressure, allowing for smoother, faster drilling with less effort and reduced wear on both the bit and your power tool.Optimized for a Wide Range of MetalsThis is the ultimate multi-purpose drill bit for Metal. Its robust construction and optimized geometry make it suitable for an extensive list of applications. It effortlessly drills through alloyed and unalloyed steel and cast steel up to a strength of approximately 900 N/mm². It is also the ideal choice for working with gray cast iron, malleable cast iron, nodular cast iron, die-cast iron, sintered iron, alpaca (nickel silver), graphite cast iron, various aluminum alloys, bronze, and brass. The right-hand cut and an optimal spiral angle of 20-30º ensure efficient chip removal, while the bright surface finish reduces friction and heat build-up for cleaner cuts. With a drilling depth of 5 times the diameter, it is perfectly suited for professional tasks in both metal and plastics.· High-performance drill bit, suitable for all types of drills in common materials.· High concentricity and rotational precision.· Ground in a conical 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 strength of approx. 900 N/mm²), gray cast iron, malleable cast iron, nodular cast iron, die-cast iron, sintered iron, alpaca, graphite cast iron, aluminum alloys, bronze, and brass. tradeinn Bricoinn
