Multi-stroke powered safety hammer system

A multi-stroke powered safety hammer system includes a hammer having a body, a cylinder within the body, and a piston carried in the cylinder for reciprocal movement therein. The system includes a quick-connect coupling mount on the hammer, the mount having an inner barrel bounding a hollow interior, an outer sleeve for sliding movement over the inner barrel, and an engagement assembly defined by the inner barrel and the outer sleeve for locking an attachment in the interior. The system includes one of many attachments with an engagement portion; when the engagement portion is applied to the quick-connect coupling mount and the hammer is operated, the piston reciprocates to impact the engagement portion. The attachments guide fasteners, remove fasteners, and process materials.
