The channel snugly, longitudinally slidably receives a metal stud therethrough with the inner and outer surfaces of the stud, except in the areas thereof registered with the aforementioned opening, backed by opposing surfaces of the die body and a cutting die is provided having the same cross-sectional shape as the cross-sectional shape of the opening and may be forced through the latter to cut away all portions of the metal stud registered with the opening.
