Drilling machines (or drilling presses / drills) are tools that use a cutting attachment to either drill holes or enlarge existing holes into a material. Drilling is used for many applications in the industrial workplace; metalworking, woodworking, construction, DIY and even in specialist applications such as space missions and tunnelling.
There are many different types of drill to suit these different applications, and ignoring the smaller handheld drills used for domestic and small scale work, the majority of drilling machines can be classified either as a bench drill or a pillar drill.
The bench drill unsurprisingly gets its name because it is attached to a bench for stability, and this allows the drilling of larger work pieces to be carried out safely and accurately as the workpiece can be restrained by a clamp or vice. Another advantage of bench drills over handheld models is that it requires much less effort to apply the drill to the work piece. The chuck and spindle are applied to the piece by a lever, giving the operator considerable mechanical advantage. It is used to either create or enlarge holes in raw materials such as wood, plastic, or even metal.
Pillar drills are a larger breed of drilling machine, and they stand upright on the floor. Due to the increased size they are in turn used both to drill larger holes in larger work pieces.
Many modern drilling machines are programmed and controlled digitally by CNC (computer numerical control) systems. Because of their precise accuracy these automatic drills are especially useful for drilling smaller holes, angled holes and pattern hole drilling. Multi-spindle drills (or gang drills as they are sometimes called) can be used to drill several holes at the same time and can save precious time if you require your drilling machine to work at high volume.
