Ruko Din 338 Hss Ground Self-centering Helical Ø 0.7 Mm Metal Drill Bit 10 Units. RUKO DIN 338 HSS Ground Self-Centering Helical Ø 0.7 mm Metal Drill BitAchieve unparalleled precision and efficiency in your metalworking with the RUKO DIN 338 HSS Ground Self-Centering Helical Metal Drill Bit. Expertly engineered for professionals and demanding applications, this 0.7 mm high-performance drill bit is the definitive choice for creating clean, accurate holes in a vast array of common materials. Its design prioritizes high concentricity and rotational precision, ensuring flawless results whether used in stationary machines or handheld power drills.Unmatched Precision and PerformanceExperience effortless and precise starts every time. The advanced conical point grinding with a split point, meticulously crafted according to DIN 1412 C, provides exceptional self-centering capabilities. This key feature prevents the bit from walking or wandering on the workpiece surface, eliminating the need for pre-punching and guaranteeing hole placement accuracy from the very first rotation. The fully ground body of this high-performance standard twist drill bit, made from robust HSS high-speed steel, further enhances its precise concentricity for superior hole quality and finish.Key Features for Professional ResultsDesigned for optimal performance, this drill bit incorporates features that set it apart. The N-type point geometry ensures excellent centering while requiring lower feed pressure, reducing user fatigue and wear on your equipment. Its bright surface finish promotes smooth chip ejection and reduces friction for cooler, more efficient drilling. The standard right-hand cut and an optimized 20-30º spiral angle work in tandem to effectively clear debris from the hole, maintaining cutting performance. The cylindrical shank is manufactured with a tight h8 tolerance, guaranteeing a secure and precise clamping in any standard chuck, which is critical for maintaining rotational accuracy and preventing slippage during operation. With a drilling depth capacity of 5 times its diameter, it is perfectly suited for a wide range of professional tasks in both metal and plastics.Versatile ApplicationsThis is the ultimate high-performance drill bit, suitable for all types of drills when working with a comprehensive list of materials.
