RUKO 214004 Pack de 10 brocas helicoidales DIN 338, tipo N HSS, fresada rectificada, con autocentrado (Ø 0,4 mm)

Ruko Din 338 Hss Ground Self-centering Helical Ø 0.4 Mm Metal Drill Bit 10 Units. RUKO DIN 338 HSS Ground Self-Centering Metal Drill Bit - 0.4 mmAchieve unparalleled precision and efficiency in your metalworking projects with the RUKO DIN 338 HSS Ground Helical Drill Bit. Expertly engineered in Germany for professional and industrial use, this high-performance drill bit is the definitive solution for drilling in a vast range of common and challenging materials. Its design prioritizes accuracy, durability, and user-friendliness, making it an essential accessory for any electric tool collection. Whether for intricate fabrication or demanding repair work, this drill bit delivers consistent, high-quality results.The standout feature of this individual drill bit is its exceptional self-centering capability. Thanks to the ground conical point with a split point design, conforming to DIN 1412 C standards, the bit engages immediately with the workpiece. This eliminates the need for pre-punching or center-drilling, preventing the bit from walking and ensuring perfectly placed holes from the very start. The result is faster, more accurate work and a reduction in material wastage. The fully ground body from a single piece of high-speed steel (HSS) guarantees superior concentricity and rotational accuracy, leading to cleaner, more precise holes with an excellent finish.Engineered for versatility, this 0.4 mm metal drill bit is your go-to tool for a wide spectrum of applications. It demonstrates outstanding performance when drilling into alloyed and unalloyed steel and cast steel up to a tensile strength of approximately 900 N/mm². Its robust geometry is also perfectly suited for working with grey cast iron, malleable cast iron, nodular cast iron, die-cast iron, sintered iron, German silver, and graphite cast iron. Furthermore, it excels in drilling non-ferrous metals, providing smooth and efficient cutting in aluminum alloys, bronze, and brass. The bright surface finish reduces friction and aids in chip evacuation, further enhancing its performance across these materials.This standard high-performance twist drill bit combines a classic N-type point with an optimized spiral angle for good centering and reduced feed pressure, allowing for comfortable and controlled operation in both handheld and stationary drills.· Product Type: High-Performance Helical Drill Bit· Standard: DIN 338· Point Geometry: Ground Conical Point with Split Point (DIN 1412 C)· Point Type: Type N (Good Centering, Reduced Feed Pressure)· Cutting Angle: 118°· Spiral Angle: 20-30º· Cutting Direction: Right-Hand Cut· Diameter (Ø): 0.4 mm· Diameter Tolerance (Ø): h8· Overall Length (L1): 20 mm· Cutting Length (L2): 5 mm· Drilling Depth: 5 x Diameter· Shank: Cylindrical Shank with h8 Tolerance· Surface Finish: Bright· Primary Material Application: Metal· Compatibility: Suitable for all types of drills in common materials. tradeinn Bricoinn
