| Apr 21, 2020 at 21:52 | comment | added | user5572 | @GernBlanston yeah, I'm going for at least one side of the cut really nice. So careful cutting with expensive forstners is probably best. I can chamfer (or not) as a second pass. I'm ok with the extra work, frankly. | |

| Apr 21, 2020 at 17:08 | comment | added | Gern Blanston | @jdv There are cone-shaped bits for countersinking holes that already exist (example), but I don't know if they come in large diameters like that without being really expensive. I have a handful of them, but they're all smaller sizes than that. They also don't give stellar looking results, so they're good for jig work, but I wouldn't use them on any finished piece. | |
| Apr 21, 2020 at 15:01 | comment | added | user5572 | @AloysiusDefenestrate that's a good idea, but right now I have more time than money, and trying to sort out getting three sheets to a CNC place in These Trying Times sounds like I'd rather stay home and make hundreds of holes by myself. About half-way through sheet #1 I may regret this decision. | |
| Apr 21, 2020 at 14:59 | comment | added | user5572 | @GernBlanston not sure, but I'm using a Forstner bit to make the holes, and I've never seen a forstner bit with a countersink cutter as well. These are over 1in in diameter, so a fair amount of material is to be removed. | |
| Apr 21, 2020 at 13:02 | comment | added | Aloysius Defenestrate | This doesn't speak to your question, but I know of someone that had a similar project to yours (drill lots of holes accurately in sheet goods). He found a local cad/cam shop that could do the work for way less than it would cost him. Maybe something to ponder... | |

| Apr 21, 2020 at 2:40 | comment | added | Gern Blanston | I take it these holes are too big for a basic countersink bit? | |
