This is for a Ingersoll Rand Air Drill with an industrial 3/*" Jacobs chuck. This is an older model, made in Japan. They are of higher quality back then. It has low use for its age and has been well maintained. It runs great and is reversible. This drill is compact enough to get into tight spaces that most other drills cannot fit. Asking $40.
