NO! Worst thing ever! I know the adapter of which you speak, they corrode and rot, and that's if you last long enough without the antenna mount pulling apart from the strain. If you have an NMO mount in place, use an NMO antenna. Those 3/4 NMO to 3/8"x24 thread adapters are the worst idea to ever exist in radio. Yes, worse than magnet mounts.
If it's a 3/4"OD hole saw, rated for metal, it will work fine.
