RUKO 214014 Pack de 10 brocas helicoidales DIN 338, tipo N HSS, fresada rectificada, con autocentrado (Ø 1,4 mm)

Ruko Din 338 Hss Ground Self-centering Helical Ø 1.4 Mm Metal Drill Bit 10 Units. RUKO DIN 338 HSS Ground Self-Centering Helical Ø 1.4 mm Metal Drill BitAchieve unparalleled precision and efficiency in your metalworking projects with the RUKO DIN 338 HSS Ground Metal Drill Bit. This high-performance 1.4 mm individual drill bit is engineered for professionals and serious DIY enthusiasts who demand accuracy and reliability. As a leading choice in electric tool accessories, this bit is suitable for all types of drills in common materials, delivering consistent, high-quality results every time.Key Benefits & Features:Effortless Self-Centering & Precision Starts: Experience frustration-free drilling thanks to the advanced conical point grinding with a split point, designed according to DIN 1412 C. This self-centering tip engages the material immediately upon contact, preventing the bit from walking or wandering. This crucial feature eliminates the need for pre-punching or center marking, saving you valuable time and ensuring perfect hole placement from the very beginning.Superior Concentricity for Flawless Holes: The drill bit´s fully ground body and exacting h8 diameter tolerance guarantee exceptional rotational accuracy and high concentricity. This precision manufacturing process minimizes vibration, resulting in cleaner, smoother, and more accurately sized holes. The bright surface finish further reduces friction and aids in smooth chip evacuation for a superior finish.Optimized for Power and Efficiency: Designed with an N-type point and a 20-30º spiral angle, this right-hand cut helical bit ensures excellent centering and efficient chip removal. This intelligent geometry requires lower feed pressure from the operator, reducing fatigue during extended use and allowing for faster, more aggressive drilling without sacrificing control or accuracy. The cylindrical shank provides a secure, precise clamping in any standard drill chuck.Unmatched Versatility Across a Wide Range of Materials: This is the ultimate high-performance standard twist drill bit for your workshop. It is expertly engineered for applications involving 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, and sintered iron. It also performs exceptionally well with non-ferrous metals such as nickel silver, graphite cast iron, aluminum alloys, bronze, and brass. Its robust design allows for professional work with a drilling depth of up to 5 times its diameter in both metal and plastics.Technical Specifications:* Diameter: 1.4 mm* Drill Bit Type: Individual Metal Twist Drill Bit* Standard: DIN 338* Material: High-Speed Steel (HSS)* Point Geometry: Split Point according to DIN 1412 C* Cutting Angle: 118°* Spiral Angle: 20-30º* Diameter Tolerance: h8* Shank: Cylindrical* Cutting Direction: Right-hand cut* Surface: Bright, Fully Ground. tradeinn Bricoinn
