Any idea what the specs for the original screw were? I have zero experience with the KJW M700, but I deal with stripped and damaged threads regularly at work.
Drilling & re-tapping would require changing the original adjustment screw for a larger one; not a problem if it's a normal grub/set screw (headless). You might be able to re-tap to a slightly larger SAE thread (I'm assuming KJW uses metric hardware here); e.g. reaming up a damaged M2.5 threaded hole and re-tapping for a 4-40 screw. Most small-diameter SAE threads are just slightly larger than the nearest metric size.
If all else fails,
Heli-Coil sells (somewhat expensive) kits for fixing this sort of problem; it involves drilling & tapping a larger hole, then screwing in a spring-like insert with the original threading inside. A local machine shop would be a good place to ask around for these; my shop has dozens of 'em, all kinds of different threads & lengths.
