A nail guiding and driving tool having a punch slidably disposed within a hollow sleeve. The punch includes a hammer blow receiving body portion containing a pair of relatively large diameter spaced apart end sections which closely fit but slide freely within a large diameter rear end portion of the hollow sleeve joined together by a relatively small diameter mid-section The punch also includes a nail driving portion which closely fits but slides freely within a small diameter forward end portion of the sleeve. A stop pin is connected in a hole in the side of the sleeve and projects into the large diameter portion of the sleeve beyond and between the outer surfaces of the end sections of the body portion at a position along the sleeve wherein a rear end of the forward end section slidably engages the pin to limit rearward sliding motion of the punch within the sleeve but wherein the forward end of the forward end section slides into an annular wall at the joinder of the rear end and forward end portions of the hollow shaft defined by said sleeve to limit forward movement of the punch in said sleeve.

A nail guiding and driving tool comprising a sleeve defining a hollow shaft, said shaft having a lesser diameter forward section opening onto a front end of said sleeve from which a nail can be driven and a larger diameter rearward section opening onto a rear end of said sleeve, punch means for driving a nail from said sleeve slidably disposed partially within said shaft, said punch means being freely rotatable in said sleeve and including a body portion having a pair of relatively large diameter spaced apart end sections which closely conform to but which are freely slidable within said rearward shaft section and a relatively small diameter central section which joins said end sections concentrically, and a nail driving portion closely conforming to but freely slidable within said forward shaft section joined to the forward most end of said end sections for slidable movement of a front end of said nail driving means between a retracted position in a rear end portion of said forward shaft section and an advanced position at least flush with the opening in the front end of said sleeve, and stop means connected to said sleeve and projecting toward said central section between said end sections for limiting the rearward sliding movement of said punch means within said sleeve without touching said central section and without interferring with the forward sliding movement of said punch means in said sleeve.
