Carbide Drill for Stainless Steel and Titanium Alloy – ADO-SUS

Work hardening, welding, elongation of cutting chips and poor thermal conductivity are common problems in the machining of stainless steels and titanium alloys. The ADO-SUS is a carbide drill series that employs a unique coolant hole shape and tool geometry to enable efficient drilling in these difficult-to-machine materials.


  1. Sharp cutting edge reduces work hardening.
  2. New flute geometry enables the creation of compact cutting chips.
  3. Special margin shape reduces friction and heat generation.
  4. New coolant hole shape “MEGA COOLER” improves coolant flow, chip evacuation and cutting heat generation.
  5. WXL coating provides high adhesion strength, which minimizes the possibility of chipping.
