Cobalt drill bits are made from an alloy of steel and cobalt (5%-8%). We all know how extreme the temperatures get when drilling through stainless steel and cast iron. Bosch cobalt drill bits are specially designed for drilling in hard steel. Thick web helix delivers fast material removal combined with increased durability for maximum efficiency and performance. Each bit is manufactured to exacting specifications and features a split point that starts on contact with no walking or skating, eliminating the need for a center punch.

Bosch CO2135 Features:

  • Withstands high-temperature applications for extended periods of time (up to 1,100 deg.F)
  • Rigid, thick helix web design adds stability to bit in tough applications
  • Surface hardened to penetrate tough abrasive materials
  • Available in jobber length, full shank
  • Engineered for drilling into light-gauge metal, high-carbon steel, aluminum and ally steel, cast iron, stainless steel and titanium
