This bit is approximately 4" wide and around 6 1/2" to 7" long, Has 4b60drb stamped in the side, also has numbers on the Ingersoll rand sticker but I can't make out most of them, this bit appears to have never been used but has some places where paint has come off. I do not know much about these bits so if I have something wrong or you have additional information feel free to let me know. Free shipping to the US!
