Is there a "rule of thumb" for the minimum round hole size that can be laser cut in thick plate ?
For example; What is the smallest hole diameter that can be laser cut in 3/8" thick mild steel ?

The old rule of thumb is the hole should not be smaller than the material thickness, As I said the old rule. These days newer machines can make smaller holes than the material thickness.

The hole I need is a little smaller than the material thickness, so it should work fine.
Thank you.
