I picked up a 3 set of indexable boring bars from grizzly and what I'm wondering is can you just plunge these style straight into solid stock to make a hole or should I drill a hole first then bore from there to make a flat bottom hole feeding side to side to flatten past the dimple from the drill ???![20160212_203013.jpg 20160212_203013.jpg](https://www.hobby-machinist.com/data/attachments/79/79328-2405cd09d44b9f72448eb808a29f34f3.jpg)
