Jobber Length Cobalt Drill Bits
Cobalt jobber length drill bits including gold oxide finshed and AlTiN coated cobalt drills.

Jobber length cobalt drill bits are general-purpose drill bits characterized by their straight shank which is the same diameter of the cutting edge, and a flute length, which yields a drilling depth of 4.5 to 8.5 times the diameter of the bit. The flute helix ranges from 21 to 30 degrees depending on the supplier.  Cobalt jobber drills are an excellent choice for small batch machining.

  • Jobber length for deeper drilling applications.
  • Optimized for drilling stainless steels, nickel-based alloys, and titanium alloys.
  • Constructed from M42 Cobalt (idnetification ring on shaft)
  • They have 135 degree point angle and they are web thinned (diameters less than .0625 are thot split)
  • Gold oxide finish extends tool life, improves lubricity and reduces stresses.
  • AlTiN coating offers increased wear and heat resistance.
  • Precision manufactured in the USA.
