Hello, I received the attached view from an outside source and can't figure out what they want with a P.F. counterbore. I know I'll kick myself when I get an answer. Does anyone know what this means? Thanks!!

My guess is Press Fit.
They want to press a plug in the c'bore to seal the .234 hole below.
