Yeah, they're the ryobicordless10mm borer which seem to enter the trunk at a 45 degree downward pointing angle whilst also pointing off to the left or right so the entire 2" hole bored by this critter is in the vascular cambium.
Sometimes they attack with such fierocity that they actually have scuff marks around the entry hole where there was a fight over who goes first. Others call this chuck marks as it's where some borers get chucked outta the hole and you can even see the sawdust swarf on the ground beneath.
