I'm getting ready to make a pen that requires a 37/64" hole for one of the tubes. As pen blanks go, that's pretty big hole. The 37/64" bit I got from WoodTurnersCatalog is a twist drill. Ordinarily, I'd use a forstner bit or a brad point. Are there any tips or warnings I should consider when drilling a hole this big with a twist drill?
