my normal files I have will cut the chrome, but it takes a long time. you can get a set of diamon files on ebay for $10
you are not the frist person to say "I wouldn't have tought you where 14" or somthing along those lines
your dreaming if you think normal files will cut the chrome......as well it also takes quite some time to cut even with diamond files...... This is not something to be taken lightly..
