Sterling Edge's ball nose and bull nose carbide inserts accomplish different tasks, but they can be used on the same job. Both style of inserts provide extremely accurate effective cutting characteristics in a wide range of materials.
The standard grind ball nose inserts and end mills remain the workhorse of cutting inserts for the tool and die industry. They are effective when used with heavier roughing cuts of profile milling. Yet they are just as dependable during the the finishing phase. Because of the grind's geometry, this ball nose can "cut to the center" to provide a smoother finish.
