Twist drill RUKO DIN 338 N HSS 101 mm DIN 338 Ø 6,5 mm High speed steel (HSS) Spiral Grinding with self-centering 10 Units

The RUKO DIN 338 N HSS twist drill bit offers a highly efficient solution for precise drilling in metals and alloys, meeting the demanding DIN 338 standard, internationally recognized for quality and consistency. Made from high-speed steel (HSS), this drill bit ensures durability and excellent wear resistance, even in intensive applications. Its ground, self-centering design enables accurate starts and reduces deviation, while high concentricity and rotational precision deliver clean, controlled holes every time. The tip angle is optimized at 118 degrees and the spiral angle between 20 and 30º, promoting efficient chip removal and improved cutting performance. The h8 diameter tolerance guarantees precise holes according to industrial specifications. With an approximate length of 101 mm, a bright surface finish, and right-hand cutting, this drill bit is ideal for both professional and industrial tasks requiring reliable, repeatable drilling. The 10-piece set provides a practical solution for workshops and businesses with high replacement needs. Suitable for a wide range of materials, including alloyed and unalloyed steels (up to 900 N/mm² strength), grey and malleable cast iron, nodular cast iron, sintered iron, bronze, brass, and various aluminum alloys, making it an extremely versatile tool for general and specialized machining. In summary, the RUKO DIN 338 N HSS is a professional twist drill bit that ensures drilling quality and versatility in demanding work environments.
