put it this way, if you chip a wood tooth spinning at 5000 RPM off the blade.....................
Metal needs to be cut slower with a fine toothed blade.
I doubt even staff at somwhere like machine mart will know what's what..
If there's an advice line in the packing give it a ring.
Evolution produce some tools that specify metal cutting..
