Answer

A general-purpose drill that is carbide and can be used in external coolant supply instead of internal coolant supply is

AD-2D and AD-4D are available.
 
Uses EgiAs coating, which has excellent wear resistance and toughness ( chipping resistance)!
Long tool life can be obtained even under extreme conditions at high cutting conditions.
 
Outstanding chip discharge!
Wavelike flute form that divides chips into small pieces
Wide flutes for improved chip evacuation
Drills with EgiAs coating have flute‑smoothed surfaces.
 
This is a general-purpose carbide drill with low resistance specifications that can be used on a variety of processing machines, from small machines and high-performance M/C to lathe machines.
