playing with the less-than-perfect milling cutter that came with the
mill/drill machine I have here (big Clarke/Machine mart one, CL1220 or
somesuch number). It's a 2" or so dia cutter with 4 carbide blades. In
this instance I was working on a bit of 50x6mm mild steel, trying to make a
straight-edge of it.
It came to my thought that there's undoubtedly a recommended speed to run
the thing at, but I've no idea what. Anyone got pointers to a decent list
of cutting speeds for different tools/materials?
