Drill Press

A drill press (also known as pedestal drill, pillar drill, or bench drill) is a fixed style of drill that may be mounted on a stand or bolted to the floor.

The main parts are the column, table, spindle, chuck and drill head. The drill head has a set of usually three handles that lower the spindle toward the table. The table can be raised or lowered along the column generally by a rack and pinion mechanism.

Early Drill Presses

The first electric drill was patented in Australia in 1889.

pillar drill

Pillar Drill patented in 1893, found in factories or large machine shops, usually driven by an overhead line shaft often powered by a steam mill engine.

post drill

Post Drill patented in 1883, hand powered by a crank, spindle was lowered by screw mechanism, usually found in the local blacksmith shop.

Additional Info

 

For precision drilling a drill press is pretty well a necessity, a good heavy duty model will have at least a 3/4 HP motor and a 5/8" chuck.

Sizing

The size of a drill press is determined by the distance the drill bit is from the column, a 12" drill press would be capable of drilling a hole in the center of a 12" disk.

A common misconception is that floor models have a larger capacity than bench tops. There are small bench top models but with the larger sizes the bench tops are equipped with the same drill head as the floor models.

Speeds

Speeds are selected by a vari-drive system or the arrangement of belts on stepped pulleys, most have three pulleys and two belts, to deliver a range of 12 or 16 speeds from
