RUKO 214043 - Pack de 10 brocas helicoidales DIN 338, tipo N HSS, fresada-rectificada, con autocentrado (Ø 4,3 mm)

Ruko Din 338 Hss Ground Self-centering Helical Ø 4.3 Mm Metal Drill Bit 10 Units. RUKO DIN 338 HSS Ground Self-Centering Metal Drill Bit - 4.3 mmExperience unparalleled precision and efficiency in your metalworking projects with the RUKO DIN 338 HSS Ground Self-Centering Helical Drill Bit. Engineered for professionals and demanding applications, this 4.3 mm individual metal drill bit delivers consistent, high-performance results across a wide spectrum of common materials. It stands as a high-performance drill bit, suitable for all types of drills and designed for reliability and longevity.The defining feature of this drill bit is its conical point grinding with a split point according to DIN 1412 C. This advanced self-centering tip eliminates the need for pre-punching or a pilot hole, ensuring immediate, slip-free starts and exceptionally accurate hole placement every time. This high concentricity and rotational precision are further enhanced by its construction. As a standard high-performance twist drill bit made of HSS high-speed steel, it features a fully ground body, a meticulous manufacturing process that guarantees superior performance, minimizes run-out, and results in cleaner, more exact holes.Designed for versatility, this is the ideal choice for a vast range of applications. Effortlessly drill through alloyed and unalloyed steel and cast steel (up to a strength of approximately 900 N/mm²), as well as grey cast iron, malleable cast iron, nodular cast iron, die-cast iron, and sintered iron. It also excels with non-ferrous metals, including alpaca, graphite cast iron, various aluminum alloys, bronze, and brass.The N-type point with good centering, combined with a precise 118° cutting angle, ensures excellent drilling initiation while requiring lower feed pressure from the operator, reducing fatigue and improving workflow. A standard 20-30º spiral angle effectively clears chips from the hole, preventing clogging and overheating for a smoother drilling experience. The bright, polished surface further reduces friction and aids in chip evacuation. With a drilling depth of 5 times its diameter, this bit is built for professional work on both metal and plastics, providing the reach needed for substantial tasks. The cylindrical shank features a precise h8 tolerance, ensuring a secure, wobble-free fit in the chuck for maximum power transfer and safety.Choose the RUKO DIN 338 HSS drill bit for its uncompromising quality and remarkable versatility. It is the dependable tool for achieving professional-grade results in maintenance, construction, and fabrication environments.Technical Specifications:* Diameter (Ø): 4.3 mm* Drill Bit Type: Individual Helical Metal Drill Bit* Material Application: Metal* Standard: DIN 338* Point Geometry: Split Point, DIN 1412 C* Cutting Angle: 118°* Spiral Angle: 20-30º* Diameter Tolerance: h8* Shank: Cylindrical with h8 tolerance for precise clamping* Cutting Direction: Right-hand cut* Surface: Bright. tradeinn Bricoinn
