In reference to a drill bit, what is a "Jobber size"?
While the word ‘size’ and ‘sizes’ is often used in conjunction with ‘jobber,’ it is technically incorrect and a misnomer that has somehow found its way into our lexicon. Jobber refers to a type of drill, not size. There are many types of drills but the simplest, easiest to produce the cheapest and most common is the twist drill known as a ‘jobber’ and they come in many, many sizes. The word ‘jobber’ is defined, in one definition, as being a person who does only occasional work, i.e., a non-professional. As such, this person would purchase the least expensive or ‘jobber’ drills to meet his needs. If anything is meant by 'jobber sizes.,' it would be twist drills with small / smaller diameters.
