Jobber Length Drill Bits

Jobber length drill bits are a type of twist drill bits commonly used in machining and drilling operations. They are characterized by their length and are designed to provide a balance between rigidity and versatility. Here are some key features of jobber length drill bits:

  • Length: Jobber length drill bits are longer than stub-length bits but shorter than longer specialty bits like taper or aircraft extension bits. They typically range from 4 to 6 inches (100 to 150 mm) in length, although the exact length can vary between manufacturers.
  • Versatility: Jobber length drill bits are the most commonly used drill bits in general-purpose drilling applications. Their length allows them to drill deeper holes without sacrificing too much rigidity. They can be used in a wide range of materials, including metal, wood, plastic, and composites.
  • Rigidity: Jobber length drill bits offer a good balance between rigidity and flexibility. The longer length compared to stub-length bits provides better reach and stability, reducing the chance of the bit breaking or deflecting during drilling.
  • Shank Design: Jobber length drill bits typically have a straight shank, which allows them to be used with various types of drill chucks, including keyless chucks and drill press chucks. The shank diameter is usually standardized, with common sizes like 1/4 inch (6.35 mm) or 3/8 inch (9.53 mm).
  • Diameter Range: Jobber length drill bits are available in a wide range of diameters, from very small sizes (e.g., 1/16 inch or 1.5 mm) to larger sizes (e.g., 1 inch or 25 mm). The specific diameter you need will depend on the requirements of your drilling application.
