A bit breaker is a specialized tool used in drilling operations. Its primary function is to hold the drill bit securely in place while the bit sub on top of it is either tightened or loosened. This is crucial because drill bits often have non-cylindrical shapes, making it difficult for conventional wrenches to fit properly12. Bit breakers are designed to match the specific profile of the bit, ensuring proper alignment and stability during the assembly or disassembly process. This helps prevent damage to the bit and improves overall efficiency and safety in drilling operations
