    THE DEVICE HISTORY RECORD WAS CHECKED AND CONFORMED TO SPECIFICATIONS, INCLUDING DEVICE HARDNESS. THE RETURNED DEVICE WAS INSPECTED AND FOUND TO HAVE FRACTURED AT THE WEAKEST SPOT, THE THREAD RUN-OUT. DIMENSIONS WERE VERIFIED AND CONFORM TO SPECIFICATIONS. THE MICROSTRUCTURE OF THE DRILL IS HOMOGENOUS AND SHOWS NO ANOMALIES. THE DRILL CORE WAS MEASURED AT THE FRACTURE POINT AND FOUND TO CONFORM TO SPECIFICATIONS. THE FRACTURE SURFACE REVEALS THAT THE DRILL WAS STRONGLY BENT, AS CAN OCCUR WHEN A DRILL IS POSITIONED OBLIQUELY OR SUBJECT TO EXCESSIVE TORSION FORCE DURING USE. ADDITIONAL INFORMATION HAS BEEN REQUESTED REGARDING THE HANDPIECE AND THE ROTATIONAL SPEED USED DURING THE OPERATION. [(B)(4)].
