- Material Selection: Generally, high-strength alloy steels such as 4145H and 35CrMo are used. These materials possess good strength, toughness, and fatigue resistance, enabling them to withstand the complex stresses encountered during drilling.
- Machining Processes: These include forging, which shapes the billet into a near-finished product, improving the material's internal structure and increasing strength; rough machining, using lathes, milling machines, etc., for preliminary machining of the outer diameter, end faces, and threads; deep hole machining, using deep hole drilling machines or gun drills to machine the center deep hole of the drill clip, ensuring the hole's straightness and dimensional accuracy; finish machining, precision machining of the drill clip's outer diameter, threads, etc., to improve dimensional accuracy and surface quality; heat treatment, through quenching and tempering, to improve the material's hardness, strength, and toughness; and surface treatment, such as hard chrome plating, to improve the drill clip's wear resistance and corrosion resistance.
- Quality Control: Rigorous non-destructive testing, such as ultrasonic testing and magnetic particle testing, is required to detect internal and surface defects. Strict measurement and control of the dimensional accuracy and geometric tolerances of the drill tip are essential to ensure compliance with design requirements. Performance tests, such as torque and tensile tests, are also necessary to guarantee the reliability of the drill tip in actual use.
