This item can come in different styles. 3100 and up. I will include one of my small bullet tip favorites, if you want more sizes of the bullet tip for like a lab or pit, get the large one by searching tips in our seach at the top of the screen. This is the upgraded model from what Dede uses for pet nail grinding.  Dede prefers a real Dremel she can use for paws and for wood and for artwork. Get training before attempting to do nail dremeling without knowing how.  All Sales Final.
