Jobber Length Drills (4D-7D) Jobber length drills refer to drills with medium to long flute lengths. For our carbide drills, OSG utilizes the designations 4D and 5D to more specifically classify flute lengths. This designation specifically defines how deep our drills can functionally drill relative to their diameter. In other words, a 1/2" 5D OSG drill can drill a hole 1-1/2" deep.
