In printing, the term “Drilling” refers to the process of creating round holes in the paper using a rotating bit. There are many print projects which require the addition of round holes. The most common application is the holes drilled through the sheets, dividers, and other inserts that get placed into a ringed binder, such as the popular 3-ring binder.
Another example is the hole (or holes) drilled through a wall calendar or tag so it can be hung. Also, laminated operating instructions are commonly hole-drilled so they can be suspended from machinery or equipment via a ring, hook or chain.
In addition, perfect-bound and saddle-stitched books – such as manuals and catalogs – are sometimes drilled with multiple holes near the spine for insertion into a binder or fixture.
Manual Punching vs Automated Drilling
Unlike a manual punch, which presses holes through one or a few sheets of paper, the drilling operation uses a specialized machine with sharp hollow bits to bore through thick stacks of paper.
A paper drill produces very clean and precisely-placed holes. Also, drilling saves valuable time because it can penetrate through hundreds of sheets at once. It can also be set up to create multiple holes in one pass.
