How can I drill a hole into a large workpiece at an exact angle? (self.woodworking)

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?

I think that's exactly what I need! At least this type of drill guide:

Why are very different kinds of tools named the same?

I commented further up, I guess I should have scrolled first. This is exactly the kind of store bought jig I meant; it should be exactly what you need, as long as the base isn't too big for wherever you need to drill.

The really cheap (Princess Auto, <$20) ones are alright but not great, the more expensive ones are fantastic

I have this exact tool, and just as a warning, it is far from perfect but it does certainly help and I've used it for many things but if precision is what you're looking for you might be better off buying a higher quality one or a chuck and building one at the angle you need.

Milescraft makes a slightly better one and then there's the rockler one but you know, you get what you pay for.
