RUKO 214055 - Pack de 10 brocas helicoidales DIN 338, tipo N HSS, fresada-rectificada, con autocentrado (Ø 5,5 mm)

Ruko Din 338 Hss Ground Self-centering Helical Ø 5.5 Mm Metal Drill Bit 10 Units. RUKO DIN 338 HSS Ground Self-Centering Helical Metal Drill Bit - Ø 5.5 mmExperience the pinnacle of drilling performance with the RUKO DIN 338 HSS Ground Metal Drill Bit. Engineered for professionals and discerning craftspeople, this high-performance 5.5 mm helical drill bit is the ultimate accessory for all types of drills, delivering unmatched precision and efficiency in a vast array of common materials. Whether you are working on a demanding industrial project or a precise workshop task, this drill bit is designed to exceed expectations.The standout feature of this bit is its exceptional self-centering capability. Thanks to a meticulously ground conical point shape with a split point, manufactured according to DIN 1412 C standards, the bit engages the material instantly without wandering or walking. This eliminates the need for a center punch, saving you time and guaranteeing perfectly placed holes from the very start. This precision is further enhanced by the fully ground body, which ensures high concentricity and superior rotational precision for smooth, clean, and accurate drilling results every time.Constructed from high-performance HSS high-speed steel, this standard twist drill bit is built for durability and sustained performance. The robust N-shaped point geometry not only contributes to its excellent centering but also significantly reduces the required feed pressure, making your drilling tasks faster and less strenuous. Its bright surface finish minimizes friction, promoting smoother cutting and better chip evacuation.Designed for versatility, this is a high-performance drill bit suitable for a wide range of applications. It excels in drilling 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, various aluminum alloys, bronze, and brass. With an effective drilling depth of 5 times its diameter, it provides the capacity needed for professional work on both metal and plastics, making it an indispensable tool for any serious project.Technical Specifications* Diameter: 5.5 mm* Drill Bit Type: Metal* Design: Individual* Standard: DIN 338* Material: High-Speed Steel (HSS)* Cutting Angle: 118°* Spiral Angle: 20-30º* Diameter Tolerance: h8* Surface: Bright* Cut Direction: Right-hand cut* Key Feature: High-performance drill bit with high concentricity and rotational precision. tradeinn Bricoinn
