I am looking for either a 11/16" or 3/4" forstner bit with a small 1/4" shank. (Be good to have both)I was thinking about 11/16" just in case I have a flute blank that is a little off. I have bored a green one and then it move a little bit. as it dries... It happens once in a while..It might be a little tight for a 3/4" bit....Just thinking ahead
