High-power paper drills aren’t your standard paper punch.

Paper DrillsAlthough it may not be the biggest topic of conversation, you may have wondered at one point in your life how holes get into reams of three-hole punched paper that you purchase at the store. Three-hole paper is one of the most widely used formats of paper used today. It is used in schools, homes, businesses and other organizations.

One of the most common misconceptions about paper drills is that the paper is not actually punched. It is drilled. Special hollow drill bits spin at high speeds and are pressed through the paper, cutting holes. The punched holes travel through the hollow drill bit where they are captured in a special tray. A one-inch stack of paper can be drilled through in less than five seconds. Some paper drills are capable of drilling through a 2 ½-inch stack of paper at once.

A common misconception is that normal wood drill presses can be used to drill paper. A normal drill bit, when applied to paper, tears it and creates unsightly burrs. Some people have actually tried to attach a hollow paper drill bit to a standard wood drill press. They are surprised when they discover it doesn’t work. The drilled paper holes that travel up the hollow bit get stuck in the bit. With no place for the drilled waste to go, the drill bit is no longer able to travel through the paper.

Some industrial wood drill presses can spin at much faster revolutions per minute (RPM) than a standard paper drill. This can be dangerous as the friction creates a lot of heat. Even with a normal paper drill, the hollow drill bits can be hot to the touch. Drill waxes and oils can be used to help reduce heat and extend drill bit life.

One-and three-spindle paper drills are commonly used, depending on the volume and job. Single-spindle paper drills often use a sliding base plate that can allow the machine to drill three holes.
