If it matters I got a m12 fuel dremel. Wondering the max thickness of metal I can cut through with it. I tried on some shelf brackets and I got a little through it but seemed like it exceeded the tool limits so I stopped.
Depends on how often you plan on cutting metal. 1-2 times a year, I’d probably suffer through with the dremel. 1-2 times a month, M18 4-1/2” angle grinder with a good quality cut off wheel. More frequent and thicker material, I’d go corded,
