AbstractA compact and portable hole punch for manually punching holes through sheet-like material to produce hole sets which enable the material to be mounted on multi-ring binders. The hole punch includes male and female plates which are pivotally mounted together. The male plate carries a plurality of punch pegs while the female plate carries die openings through which the punch pegs penetrate to cut the openings in the material when the plates are pressed together. The female plate is formed with extension portions which provide surfaces permitting the user to releasably hold the material during the punching operation. A receptacle is removably mounted on the female plate for catching waste material from the die openings, and an adjustable stop guide is mounted on the receptacle or directly into the female plate. Fingers are provided on the male plate for yieldably urging the plates to a neutral position, for releasably holding sheet-like material during the cutting operation, and for pushing the material free of the punch pegs after the cutting operation.
