I need to drill holes at exact positions to affix large workpieces to my cnc for two-sided machining. My drill press is not large enough to reach all drilling positions, and drilling by hand often results in a non-90° angle. I know for metalworking there are magnet drill presses to drill holes in steel beams. But is there something similar for wood?

How precise does the angle need to be? I can usually get really good precision for a couple cuts by just using 90 degree reference surfaces on two sides of the bit. So either an inner 90 corner or 2 gauges setup tangential to each other. That may not give enough precision for what you need though.
My suggestion would be to use a plunge router to create a 2 - 3" deep hole (not sure how deep you need to go) then follow up with a drill bit in a hand drill to finished depth. The routed hole will keep your drill square.
