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?
Then you likely want a hard drill bushing. That’ll let it be thinner than a wood jig, but still tool steel to not wear out. (Wood to support the bushing)
