Stub Length Cobalt Drill Bits
Cobalt stub length drill bits including gold oxide and AlTiN coated finishes.

Stub length cobalt drill bits are characterized by their straight shank which is the same diameter of the cutting edge, and a flute length, which is shorter and stronger than jobber length drills. They are an excellent choice for small batch machining.

  • Stub length for increased rigidity.
  • 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 too life, improves lubricity and reduces stresses.
  • AlTiN coating offers increased wear and heat resistance.
  • Commonly refered to as Screw Machine Drills
  • Precision manufactured in the USA.
