AT Jobber Length Drills

AT jobber length drills—often called standard-length twist drill bits—are general-purpose drills used across fabrication, maintenance, and machining environments. Jobber length is the most common drill bit length style, offering a practical balance of reach and rigidity for everyday holemaking in metal, plastics, and other materials (application dependent). Whether you’re drilling clearance holes, pilot holes, or production holes, selecting the right drill comes down to matching size, material, and point geometry to the job.
