The 55 degree integral alloy drill bit is made of high hardness tungsten steel material, which is integrally formed and has excellent wear resistance and fracture resistance. Its 55 degree top angle design optimizes the distribution of cutting force, reduces axial resistance during drilling, and improves chip removal efficiency, while ensuring the smoothness of the hole wall. The spiral groove, after precision polishing treatment, can effectively guide the rapid discharge of chips and avoid the formation of chip lumps. The cutting edge adopts high-quality coating technology to enhance surface hardness, reduce friction coefficient, and is suitable for high-speed deep hole drilling conditions. The straight handle structure ensures clamping stability.
