When a leading fighter jet manufacturer changed their aircraft manufacturing process, necessitating drilling out through the face-down outer mold line (OML), it was necessary to explore custom tool options. A PCD drill made adequate holes, but the process was slow and the tools were expensive. Having enjoyed good results with an AMAMCO diamond-coated compression router, the manufacturer looked to us for a new drilling solution.

We developed this diamond-coated composite drill that drills 12.5 times faster than the PCD drill and lasts 4.36 times longer.
