True or False: Over-tightening when assembling the ninety-degree drill motor is safe for the carbide drill-reamer.

Over-tightening when assembling the ninety-degree drill motor is not safe for the carbide drill-reamer because excessive torque can lead to mechanical failure. Carbide drill-reamers are designed for precision and durability, but they can become brittle if subjected to extreme stresses. If the drill-reamer is over-tightened, it may crack or break during operation, resulting in damage to both the tool and the material being worked on. Proper torque specifications are critical to ensure that the tool functions effectively without risk of failure, which highlights the importance of following manufacturer guidelines when assembling equipment. Each tool has specific torque limits that, if exceeded, compromise performance and safety.
