I am new to cnc and I have a very basic knowledge in carving bits. I actually got xcarve for wood carving. Now my bits are breaking so i want ot order some more of them but I dont live in USA so i was wondering if I could order them from local shops around me but i am not quite sure what kind of bits do I ask for. And also if someone would explain me what is the difference between drilling bits and milling bits? Please kindly advise me what kind of bits do i ask when i go to normal hardware store.
