A little bit confused as wot to use for cutting out my holes for my fin plugs, post glass. there 's the usual hole saw and shapers australia sell a bore bit, do i hole saw first through the glass then remove glass layer then bore with special bit, or can i get away with a bog standard hole saw?
Forstner bit is the way to go. One cut and done.
Sammy is right, Forstners are the best here. A hole saw will work fine too but you have to dig out the "core" after drilling. Use a screwdriver to pop the core out.
