Paper Drill Info

Electric paper drilling is a method of drilling round holes into thick wads of paper between 30mm and 50mm in depth as a means to file or archive thick documents. These machines are commonly seen in legal firms or in large corporations and Government departments.

The drilling process is achieved by a thick wad of paper being locked down firmly into position by the machine’s clamp. The operator switches on the machine which drives a very fast rotating spindle or spindles. The machine handle is pulled down as the drill bit rotates at a very high speed through the paper stack dispelling the paper waste up through the hollow shaft of the drill bit and captured in a receptacle.

Paper drill bits are available in different hole sizes from 3mm up to 12mm diameters depending on the model paper drill. The standard arch lever folder is 6mm in diameter and is therefore the most common sized drill bit used.Single spindle drill bits need regular sharpening and are protected from drilling through the metal paper table by protection strips known as baseboards or fibre boards. These boards look much like cardboard but are manufactured from very dense natural fibrous pulp.

Manual hole punch machines are limited to only one or a few sheets punched through at once. Electric paper drills effortlessly drill through as many as 500 sheets or a whole ream of paper electrically.

The drill depth capacity varies relative to the specific model. For in-house drilling of small volumes and for office purposes most machines are either single or dual spindle machines. Single spindle paper drills such as the Lihit 1013 work by setting a hexagonal pre-programmed bar to the desired hole pattern.

The bar has a pre-set series of slots grooved into the bar which act as stoppers and are set at common hole patterns. As the sliding table is moved across the drilling table it stops at each drilling point then is released by a button after each drill is complete. There are normally 5 commonly used hole patterns on the program bar; each having a different pattern of holes on each face and there is one plain face for customised hole patterns. Dual spindle paper drills such as the Lihit 2005 model have 2 specific spindles which drill two holes through 50mm in one action.
