More### About Chamfering with Ball/Bull End Mills Inventor

2021-2-18 Inventor CAM supports chamfering with ball end mills and bull end mills. This may be useful in cases where you are already using a ball or bull end mill in a part and wish to chamfer off sharp edges, but save a tool change to an ordinary chamfering tool. With small chamfer sizes, the differences between a flat chamfer using a chamfering tool and a slightly rounded chamfer may be negligible
