A drill press is a drill head mounted on a rigid column supported by a
base, which may be fixed to the bench (it is referred to as a bench drill
) or placed on the ground (column drill press). It is equipped with a
table, which may be tilting, and allows the workpiece to be restrained.
A capstan (lever ) allows the bit to descend without effort towards the
table to ensure the drilling of a perpendicular hole. It allows mass drill-
ing tasks to be carried out with great accuracy. Thanks to an integral
depth guide, it can create blind holes (i.e. without totally piercing the
part). It is a machine designed to work metal but other materials as
well ( plastic, wood; etc..) with the correct tools.
Equipped with a keyless or keyed drill chuck, they can also, according to the various
models, take directly in their drift, bits where the upper edge ends in a Morse taper
therefore not requiring a chuck.
In general:
There are drill presses equipped with radial drilling heads in order to increase the size
of the swan-neck (i.e. the column-bit distance ).
Rotation speed is adjustable in order to adapt to the diameters of the bit and material
to be drilled.
In practice, at the time of drilling, the chip must emerge in a continuous manner.
Adapt the rotation speed of the chuck to the diameter of the drill:
- Small diameter = high speed
- Large diameter = low speed
The choice of speed is made by combining the position of the belts on stepped pul-
leys. Some machines are equipped with mechanical or electric speed controls provi-
ding convenience of use by reducing handling.
The part must be properly secured, either held in place on the table or in a vice. What
is more, the drill chuck protection panel must be in place.
