What is a potential safety hazard when using a dull drill bit on the drill press?

A dull drill bit can create several potential hazards, but one of the primary concerns is overheating. As a dull bit struggles to penetrate the material, it generates excessive heat. This heat can lead to the bit becoming so hot that it may weaken the metal or even cause thermal damage, which in turn can lead to shattering or chipping of the bit.

In terms of safety, if a drill bit shatters while in use, it can eject sharp fragments that pose a risk of injury to the operator or nearby individuals. This makes it critical to use sharp drill bits that are properly maintained to avoid dangerous situations.

While stalling of the drill may occur due to excessive force or contact with the material being drilled, and oversized holes can be a result of various issues including technique, they do not directly correlate with the immediate safety hazard that arises from using a dull drill bit. Therefore, recognizing and addressing the need for sharp tools is crucial in ensuring safe operation when using a drill press.
