CYLINDRICAL HELICAL DRILLS "BASIC", POLISHED GROUND, LONG SERIES

The “Basic” long series cylindrical twist drills are manufactured with a polished ground finish, ensuring a uniform surface and good dimensional accuracy. Their helical geometry is designed to optimise chip removal during drilling in metallic materials. The long series allows for greater drilling depths compared to standard drills, offering versatility in operations requiring access to deeper areas of the workpiece. These tools are suitable for drilling operations with machine tools and drills, maintaining a balance between robustness and penetration capability. The cylindrical shank allows for stable clamping in the chuck, ensuring precision and reliability in the machining process.
