While having a discussion about chuck, Technician A says that chuck runout is allowed to be up to 0.010" in a consumer drill. Technician B says that it is allowed to be 0.005" in a commercial drill. Who is correct?

Question

Quizplus · Accepted Answer

Both Technician A and Technician B are correct. The allowable chuck runout can vary depending on the type of drill. For consumer drills, a higher tolerance for runout, such as 0.010", is often acceptable due to their less demanding applications. For commercial or industrial drills, which are used in more precision-demanding environments, a tighter tolerance, such as 0.005", is typically required to ensure the accuracy and quality of the work.
