I have ordered some boards with PCBway but forgot to update the board shape layer for a hole that shall be used to mount the board with a screw. Now that the boards have arrived assembled with components, what can I used to drill a hole on this PCB? I was thinking of using a Voltera V-One which I already have but apparently this tool cannot drill holes safely with FR4 material (something to do with releasing fiberglass particles in the air). Is there any options I can try? Is it safe to drill using drill press? Don't really want to re order the boards due to the cost. The hole is isolated from the components on the board (no copper close to worry about).
