What additional protective equipment is required when using a drill press, alongside safety goggles and arm covers?

When operating a drill press, using a face shield in addition to safety goggles and arm covers is crucial because it provides an extra layer of protection for the face and neck against flying debris and chips that can be generated during drilling processes. The face shield helps to guard against any potential injuries from shrapnel, coolant, or other materials that could be ejected, which safety goggles alone may not fully protect against.

While other protective equipment, such as hard hats, ear plugs, and respirator masks, may have their own importance depending on specific work environments and tasks, they do not specifically address the risks associated with the debris and particles that can be produced by a drill press operation. Thus, the face shield is the most appropriate additional equipment to ensure comprehensive personal protection in this context.
