Drill Bits - Jobber Drills

Jobber Drills are the most commonly used length of drill. The length of the flutes is between 9 and 14 times the diameter of the drill depending on the drill diameter. They offer a good balance of strength and reach, fit standard drill chucks and machines and are available in HSS, cobalt, carbide-coated versions.

The term "jobber" refers to its standard length-to-diameter ratio, making it versatile for a wide range of applications.

Common Materials

  • High-Speed Steel (HSS): General-purpose drilling.
  • Cobalt HSS: Better for stainless steel and harder metals.
  • Carbide: High-performance drilling in hard materials and production environments.

Limitations

  • Not ideal for very deep holes.
  • Less rigid than stub-length drills.
  • May require lubrication when drilling metals to reduce heat and wear.
