Consider it, Jack, as they do use less power than a shoulder mill like the F4041 that you have. Of course these are only good for milling flat faces and cannot get close to a shoulder. It can be used for milling a 45º weld prep and if you stop short of the first pass by the equivalent of your depth of cut, you're not limited to the length of the lead angle on the insert.
As stated in the very first post in this thread, the lead angle face mills give chip thinning effect so you can take a deeper cut or feed at a higher rate than you could at an equivalent width of cut with a 90º shoulder mill.
