Abstract: A tool that enables the forming of a hole in irrigation pipe, and the placement of an emitter device into that formed hole, includes a pair of elongate plier half-members connected at a pivoting joint. A first jaw includes an inwardly-directed hole punch member, while the second opposed jaw includes an inwardly-directed concavity to engage a piece of irrigation hose, such that closure of the jaws causes the hole punch to pierce a hole in the irrigation pipe. The jaw ends each include semi-cylindrical cavities sized to hold the cylindrical body of an emitter, to facilitate forcible insertion of the spike of the emitter into the hole previously formed in the irrigation pipe.
