| Summary: | A bushing and associated drill are provided that may be actuated either pneumatically or with a spring in order to be biased into contact with a structure, such as a multi-layer structure, to reduce gaps therewithin. The bushing includes a housing and a nose piece slidably disposed relative to the housing. The bushing also includes a gas inlet in communication with the internal cavity such that the nose piece may be pneumatically urged forwardly relative to the housing and into operable contact with the structure. The bushing may also include a mounting mechanism for releasably attaching the housing to a drill motor. The mounting mechanism permits the housing to be detached from the drill motor to access the internal cavity, thereby permitting a spring to be inserted that will bias the nose piece forwardly relative to the housing. Spring actuation may be an alternative or a supplement to pneumatic actuation. |
