Cost effective tool to create answer keys for bubble answer sheets.
A Challenge paper drill bit is a cost effective tool to create answer keys for bubble answer sheets. You have to sacrifice a 5mm socket to adapt the paper drill bit for use in your drill--super glue the 5mm socket in the base of the paper drill bit. The paper drill bit will require more time to create the answer key but is cheaper than a long reach paper punch which cost on the order of $150.00.
