Re: Cutting above waterline hole in boat
Have to go with sailor dave on the Forstner bits.. I used several on a recent project.. they work great for clean holes and cut better than the average holesaw, IMO, but they do make a mess. For single skin or even cored glass up to an inch or so I'd go with a holesaw.. I was drilling through glass encapsulated 2" timbers so the depth of most holesaws was problematic, as would removing the cores have been. The Forstner bit did a good job despite the large amount of shavings.
