True or False: Using lubrication on the drill bit is optional when drilling pilot holes.

Using lubrication on the drill bit is essential when drilling pilot holes, especially when working with metals and other tough materials. Lubrication serves several important purposes in the drilling process. It reduces friction between the drill bit and the material being drilled, which can prevent overheating that may lead to damage to both the drill bit and the workpiece. Additionally, lubrication helps to remove debris from the cutting area, aiding the drill bit in cutting smoothly and efficiently.

Without lubrication, the risk of drill bit wear increases significantly, which could affect precision and result in a less-than-optimal hole. While there are certain materials and circumstances where lubrication might be considered optional (such as drilling into softer woods), the practice of applying lubrication is generally recommended to ensure the best outcomes during drilling operations, thus supporting the assertion that lubrication should not be deemed optional for pilot holes in most cases.
