Drilling

 

Paper drilling describes the technology of drilling round holes into paper.

 

Hollow paper drill bits are clamped into a driven spindle which drills into the pile of paper. Unlike hole-punching, where only one or a few sheets can be punched at once, a larger number of sheets can be processed with a paper drilling machine. Drilling machines used to drill down into stacks of paper can be a range of sizes and allow different locations on the paper. Drilling is most commonly used for paper that needs to be placed into binders or printed jobs that need to be bound with a snap ring or a chicago screw.
