Flush Drills

Precision Coolant Hole drills

AERO INDUSTRIES supplies coolant hole drills specifically designed to drill EDM graphite. These drills are specially designed with special points to give you longer drill life because of less chip load. They follow the pilot hole better which means straighter holes. Both short flute(fast spiral) and long flute (regular spiral) to give you maximum performance on any graphite electrode drilling job. When drilling deeper flush holes, the long flute drills will clear the chips faster..
