The influence of formation lithology on drill bit failure is reflected in drilling skills: affecting drilling speed and drill bit footage; causing complex situations such as well leakage, blowout, well collapse and drill stuck during drilling; causing changes in mud properties; affecting wellbore quality, such as well inclination and well diameter irregularity, which in turn affects cementing quality. By analyzing the formation lithology and its influence on drilling skills, the rationality of drill bit selection and use can be judged.
Let us be straight up about the answer: for a good drilling bit, the body should use 42 CrMo and be forged from round steel.
