The Swingline SmartTouch 2-Hole Punch is a strong choice for consistent hole punching, with metal construction, fixed punch heads and an edge guide for precise punch alignment. The wide, comfortable, soft grip handle makes it easier to punch and locks in closed position for easy storage. Low force punch requires 50% less effort to operate than standard punches, and cuts through paper with minimal effort on the part of the user. Pierces through up to 20 sheets of paper, cutting clean 9/32” holes. Cleanup of punched holes is simple with a convenient opening built into the base. The hole pattern in the base allows the user to see when the chip tray is full. Swingline backs this high-quality punch with a limited 1-year warranty. 6 Pack.
