The A Brand ADO drill series is OSG's premium line of carbide coolant-fed high performance drills, designed to drill in a variety of steels up to 50X diameter without pecking. New point geometry creates sharp cutting action for reduced thrust forces, while our proprietary EgiAs coating provides drastically higher hardness and heat resistance, enabling higher drilling speeds and incredible tool life.
Wavy form cutting edge design
Sharper cutting action reduces thrust forces and produces smaller chips for easy hole processing
Internal coolant holes
Coolant delivery at the cutting edge reduces heat and improves chip evacuation, thereby increasing tool life and enabling faster drilling speeds.
