RUKO HSSE Co 5 Short Twist Drill Bit, DIN 1897, Type N, Bright Finish, 10.2 mm Diameter, 89.0 Length, R202102E

Ruko Din 1897 Short Hss-co 5 Ground Split Point Helical Ø 10.2 Mm Metal Drill Bit 10 Units. RUKO DIN 1897 Short HSS-Co 5 Drill Bit - 10.2 mm for Precision Metal DrillingExperience unparalleled precision and durability with the RUKO DIN 1897 Short HSS-Co 5 Ground Split Point Helical Drill Bit. Engineered for professional-grade performance in electric tool accessories, this 10.2 mm metal drill bit is the ultimate solution for drilling in a wide range of challenging materials. Its specialized design makes it an essential component for any workshop focused on metalworking, fabrication, and maintenance. This is the individual tool of choice for professionals who demand accuracy and longevity from their drill bits.Designed for superior performance and longevity, this short and stable standard drill bit offers exceptional control and high resistance to breakage, making it perfect for working with thin materials such as steel sheet without causing deformation. Crafted from a high-performance high-speed steel and cobalt alloy, it boasts a significantly higher thermal setting resistance. This means the bit maintains its hardness and cutting edge even at high temperatures generated during intensive drilling, ensuring a longer service life and consistent, reliable results job after job.The key to its exceptional accuracy lies in the precision-ground conical point grinding with a split point, manufactured according to DIN 1412 C. This advanced tip design provides excellent self-centering capabilities upon contact with the material. It eliminates the need for pre-punching or a pilot hole, allowing for immediate, precise starts and significantly reducing bit walking on both flat and curved surfaces. This feature saves time and ensures perfectly placed holes every time.Versatile Applications Across Demanding MetalsThis robust drill bit excels where standard bits fail. Its specialized geometry and material strength make it ideal for a vast array of demanding applications. It is engineered for drilling alloyed and unalloyed steel up to a strength of approximately 900 N/mm². Furthermore, it effortlessly tackles tough materials like grey cast iron and malleable cast iron. The high cobalt content makes it exceptionally effective on high-chrome alloy steels, including difficult-to-machine materials such as stainless steel (V2A/V4A) and other acid and rust-resistant steels, delivering clean and precise holes with minimal effort.The right-hand cut design, combined with a specialized 20-30º spiral angle, ensures efficient chip evacuation for cleaner holes and smoother operation. The aggressive 135º cutting angle is optimized for fast and efficient material penetration in hard metals. Adhering to a strict Ø tolerance of h8, each bit guarantees dimensional accuracy for critical tasks where precision is non-negotiable. The distinctive golden brown surface is indicative of a heat treatment process that reduces internal stress and enhances durability. For convenient storage and protection, the bits are supplied in a robust translucent plastic case with a red background label, keeping your high-performance tools organized and ready for the next job.Technical Specifications:* Product Type: Short Helical Drill Bit (DIN 1897)* Diameter: 10.2 mm* Target Material: Metal* Point Style: Conical Point Grinding with Split Point (DIN 1412 C)* Cutting Angle: 135º* Spiral Angle: 20-30º* Diameter Tolerance: h8* Cutting Direction: Right-hand cut* Surface Finish: Golden brown. tradeinn Bricoinn
