For the most part, I work with aluminum or other soft metals but I have a project I need to do. I need to modify some bearing blocks that are a mild steel and prefer to use my carbide bits over my Chinese HSS.
Since I work with mostly soft metals and use fairly small bits, I have my spindle speed set pretty high. It does the trick and I never really bother with the math.
Switching spindle speeds isn't fun. It doesn't take that long, I know, but it's still not fun.
Anyhow, I am thinking of using a 1/2" carbide end mill.
I believe I've calculated that I need 400-500 rpm to get the best cutting and not damage the bit. Does this sound accurate? I don't have a water cooled system
