Versatile hole punch requires absolutely no effort to switch from two-hole to three-hole format. No screwdrivers or adjustments are needed. One side is a dedicated three-hole punch, while the other side is a dedicated two-hole punch. Lever handles slice through up to 20 sheets of 20 lb. paper with ease. Punch drills 9/32" holes in a standard three-hole or standard two-hole (2-3/4" centers) pattern. Hole punch includes a high-capacity chip pan and lock-down handle for easy storage.
