We feel confident that this is a Hardwood Stump Borer, Mallodon dasystomus, which is pictured on BugGuide. According to Beetles of Eastern North America by Arthur V. Evans: “Mandibles nearly horizontal” while of the similar looking Live Oak Root Borer, Archodontes melanoplus, the author writes: “Mandibles nearly vertical.”
