Abstract

A bung tool has a cylindrical body with a four-armed drive portion projecting from one end thereof and a six-armed drive portion projecting from the opposite end thereof, respectively for engagement with different types of bungs. A drive member reciprocates in a square cross-section axial bore through the body, being manually moveable by a handle which projects radially through a slot in the body. The drive lug of an associated drive lever is receivable in the opposite ends of the bore for respectively driving the two drive portions. The drive member reciprocates among two recessed positions respectively spaced from the opposite ends of the bore to allow insertion of the drive lug therein and a drive position projecting from one of the drive portions for driving engagement with a bung cap.
