A Brand ADO-SUS (5200)

High Performance Coolant-Fed Carbide Drills for Stainless Steel


The A Brand ADO-SUS drill series is OSG's premium line of carbide coolant-fed high performance drills, designed to drill in stainless steel. New "Mega Cooler" coolant hole shape improves coolant flow, chip evacuation and cutting heat generation. This reduces work hardening, which leads to longer tool life during tapping and reaming operations. While our proprietary WXL® coating provides drastically higher coating oxidation temperature and hardness that dramatically improves wear resistance.



OSG's WXL® nano coating technology

Higher coating oxidation temperature & hardness dramatically improve wear resistance

Wavy form cutting edge design

Sharper cutting action reduces thrust forces and produces smaller chips for easy hole processing

"Mega Cooler" internal coolant holes

Improved coolant delivery at the cutting edge supresses heat buildup and improves chip evacuation, thereby increasing tool life and enabling faster drilling speeds.

New flute geometry

Enables the creation of compact cutting chips

Special margin shape

Reduces friction and heat generation
