Adding countersinks to formed stainless sheet metal
D
Hello, I’m working on a sheet metal enclosure (as in the image) that requires flush mounting for M6 countersunk screws. I need to add a countersink on a few holes, but the part is already flat-cut and formed. Has anyone successfully added a countersink post-process in this kind of setup without warping the part? Looking for the most practical approach, either manual or otherwise.
