Way too slow! (especially feed, and probably SFM)
With insert tools, you kind of need to start with the manufacturer's recommendations. Sometimes the intended use will blow your mind. For instance, we dry mill mild steel (1020) at 1300 sfm with Sandvik inserts, and I know the high-feed insert tools take advantage of feedrates that are simply unbelievable. Haven't had the chance to use one of those yet.
Also, use air blast instead of coolant on insert tools in steel for milling, turning is different, since the cut isn't [normally] interrupted. The thermal shock will greatly reduce insert life.
If you don't have the manufacturer's data, somebody here can give you a starting point, but you'll need to provide a bit more detail on your tool and application.
