Cutting Tools For Automotive Applications 

The EXOCARB-WDO drill series is OSG's premium line of carbide coolant-fed high performance drills, designed to drill in a variety of steels up to 30X diameter without pecking. New point geometry creates sharp cutting action for reduced thrust forces, while our proprietary WD1 coating provides drastically higher hardness and heat resistance, enabling higher drilling speeds and incredible tool life.


  • OSG's WD1 Nano Coating Technology
  • Wavy form cutting edge design
  • Internal coolant holes
  • Higher coating oxidation temp & hardness dramatically improve wear resistance
  • Sharper cutting action reduces thrust forces and produces smaller chips for easy hole processing
  • Coolant delivery at the cutting edge reduces heat and improves chip evacuation, thereby increasing tool life and enabling faster drilling speeds.


  • Aluminum Alloy, Cast Aluminum, Cast iron, Carbon Steels, Alloy Steel, Die Steel, Stainless Steel, Hardened Steel <50Rc
  • Holes up to 3X diamter in depth, where coolant-thru is an option.
  • Any application where productivity and the lowest cost-per-hole is the goal.
