After putting a bunch of various size holes in a part (via trace/clear) I need to put countersink to different depths. I have tried to use the drill command with a countersink tool but I cannot control the depth. I tried putting a negative number for the “drill through depth” modifier. I cannot see any alternatives using any of the other operations. Am I missing something obvious?

Thanks
