Jobber Length Carbide Drill Bits – Choose Your Size

Jobber Length Carbide Drill Bits

These are standard jobber-length solid-carbide drill bits for precision drilling in common shop and CNC applications. “Jobber length” is the most common drill length format — offering a good balance of reach, rigidity, and chip evacuation.

  • Best for: plastics, wood, aluminum, brass, composites, and general-purpose drilling where a rigid carbide drill is preferred
  • Jobber length means: a standard overall length (not stub-length and not extra-long) for predictable clearance and handling
  • What you’ll receive: the exact diameter shown on the product page (each listing is a single size)

Choosing the Right Size

Select the diameter you need based on your hole requirement and the material. If you’re drilling softer materials (plastics/wood), prioritize chip clearance and conservative feed to avoid melting or clogging. For aluminum and brass, use appropriate lubrication and avoid excessive RPM for larger diameters.

Need PCB / Micro Drills Instead?

If you’re looking for 3 mm shank micro drills (common in PCB drilling), those are typically a different format than jobber length. Use the PCB drill collections for those tooling styles.
