Upon completion of the investigation it was noted that the perforators were measured prior to sending to the supplier for evaluation and were found to be within specifications.Supplier evaluation did not confirm the complaint of "dullness".The customer¿s perforators met functional test acceptance criteria as well as dimensional test acceptance requirements for inner and outer drill flutes.Device history records (perforator assembly as well as inner and outer drill components) show all tests and inspections, including a drilling test on each perforator, met specifications.Note: further evaluation is presently being conducted to further determine the root cause of this complaint and include implementing more detailed work instructions at symmetry for the manual deburring process.Any addition evaluation reports for this complaint will be added to this file when completed.Based on the results of this investigation no further action is required.Trends will be monitored for this and similar complaints.At the present time this complaint is closed.
