What are guards used for in power tools?

Guards are primarily used on power tools to provide protection from moving parts. The main function of these safety devices is to shield the operator from coming into contact with dangerous components, such as blades or rotating bits, which can cause injury. By having guards in place, the risk of accidents is significantly reduced, as they help contain flying debris and protect the user from inadvertent contact with moving elements of the tool.

In terms of operational aspects, while increasing power output, adjusting speed, or enhancing grip might be features associated with some tools, they do not pertain to the primary purpose of guards. Guards focus specifically on safety, ensuring that users are protected while operating equipment designed to perform various cutting, shaping, or drilling tasks.
