Minimum hole diameter vs sheet thickness 316L
F
Hello, I would like to produce a stainless steel 316L bracket, 3 mm thick, cut by fiber laser. I need to include several small holes for drainage and fastening, and I’ve heard there might be a rule that the minimum hole diameter shouldn’t be smaller than the material thickness. Is this a strict limitation in practice for 316L, or are there process adjustments (e.g. slower cutting, gas type) that allow smaller holes without compromising quality?
