Unlock More Design Possibilities Take your cardboard creations to the next level with our Hole Punch Tool! Designed for young makers and STEM enthusiasts, this tool allows kids to punch precise holes in cardboard to create moving parts, thread rope, connect pieces, and even start cuts from the middle of a cardboard sheet! Tips: Each ridge of the hole punch corresponds to a different hole diameter—the higher the number, the bigger the hole! Simply hold the tool like a screwdriver and twist into the cardboard—the more you twist, the cleaner the hole! Once punched, place the hole over the ChompSaw’s cutting head to make internal cuts! With no sharp edges, our hole punch was designed to keep kids safe while making holes fast and frustration-free!
