RUKO 2140625 - Pack de 10 brocas helicoidales DIN 338, tipo N HSS, fresada-rectificada, con autocentrado (Ø 6,25 mm)

Ruko Din 338 Hss Ground Self-centering Helical Ø 6.25 Mm Metal Drill Bit 10 Units. RUKO DIN 338 HSS Ground Metal Drill Bit (6.25mm, 10-pack) offers precision and efficiency. Featuring self-centering split point technology for immediate, accurate starts without center punching, these bits minimize wander and reduce feed pressure. Crafted from robust HSS, their fully ground body ensures high concentricity and rotational accuracy for clean, precise holes. The 118° point and optimized helix angle promote efficient chip removal. Ideal for alloyed/unalloyed steel, cast iron, aluminum, bronze, and brass, these versatile drill bits are essential for any metalworking task. RUKO DIN 338 HSS Ground Metal Drill Bit | 6.25 mm | Self-CenteringExperience unparalleled precision and efficiency with the RUKO DIN 338 HSS Ground Metal Drill Bit. Engineered as a high-performance standard twist drill bit, this 6.25 mm helical bit is the ultimate solution for professionals and demanding enthusiasts seeking clean, accurate holes across a vast array of common materials. It is perfectly suitable for all types of drills, making it a versatile and essential addition to any toolkit.Superior Accuracy and Flawless PerformanceAchieve flawless results thanks to an exceptional design focused on precision. This high-performance drill bit boasts superior high concentricity and rotational accuracy, a direct result of its fully ground body crafted from robust HSS high-speed steel. This meticulous manufacturing process ensures that every rotation is perfectly centered, minimizing vibration and guaranteeing a clean, precise cut. The cylindrical shank is manufactured to a tight h8 tolerance, ensuring a secure, wobble-free clamp in the drill chuck. This precise fit translates directly to cleaner entry and exit holes, reduced wear on both the bit and your power tool, and an overall superior finish for your professional work in metal and plastics.Engineered for Efficiency and Ease of UseThe standout feature of this drill bit is its advanced self-centering capability. The conical point grind, featuring a split point meticulously shaped according to DIN 1412 C, allows for immediate and aggressive drilling without the need for a preliminary center punch. This design, combined with the general-purpose N-type point, significantly reduces the required feed pressure, enabling a faster, more controlled start and preventing the bit from walking or wandering across the material surface. The 118° cutting angle and 20-30º spiral angle are optimized for efficient chip removal, ensuring a smooth and continuous drilling process even at a drilling depth of up to 5 times the diameter.Unmatched Versatility for MetalworkingThis is the go-to individual drill bit for a comprehensive range of applications. Its robust construction and optimized geometry make it ideal for working with:* Alloyed and unalloyed steel (up to a tensile strength of approx. 900 N/mm²)* Cast steel, grey cast iron, malleable cast iron, and nodular cast iron* Die-cast iron and sintered iron* Nickel silver and graphite cast iron* Short-chipping aluminum alloys* Bronze and brassWhether you are in a fabrication shop, on a construction site, or in a home workshop, this RUKO drill bit delivers consistent, reliable performance every time. The bright surface finish and classic right-hand cut design are hallmarks of a quality tool built for durability and effectiveness.Technical Specifications* Attribute Diameter: 6.25 mm* Attribute Application: Metal* Attribute Type: Individual Drill Bit* Standard: DIN 338* Material: HSS High-Speed Steel (Ground)* Point Angle: 118°* Helix Angle: 20-30°* Diameter Tolerance: h8* Surface: Bright* Cut Direction: Right-hand* Shank: Cylindrical* Drilling Depth: 5 x Diameter. tradeinn Bricoinn
