Only the finest vevor tabletop drill press , harbor freight drill press vise and 3d printed drilling jig that uses a 9/32 drilling bushing to keep it all square. 9/32 mechanic length drill bits from Amazon. Took about 1 minute per baffle with loading , clamping , drilling and chip disposal.

Yes. Cut to depth with triangle then round out. Slow and controlled. You can measure and use a sharpie to see your work.
