How a Pillar Drill Works

How A Pillar Drill Works

A pillar drill, also known as a ‘drill press’, is a stationary drill that is used to bore through material such as wood and metal. It is typically mounted onto a stand or workbench.

The pillar drill consists of four main components: the base, column, table and head. The base is the most important part of the machine, as it provides the drill with stability and allows it to be fixed firmly to the ground. The column is the support for the head, which is the part that moves up and down the column. The table is mounted onto the column and provides the workpiece with a stable platform. Finally, the head is the part that contains the motor and the drill bit.

The head is the most important part of the machine, as it contains the motor, the drill bit, and the controls for the drill. The motor is what powers the drill, and is usually an electric motor. The drill bit is inserted into the chuck and is what bores into the material. The controls on the head allow the user to adjust the speed and depth of the drill.

The pillar drill is powered by turning the power switch on and then depressing the start button. This causes the motor to start and the drill bit to rotate. The user then turns the speed control to the desired speed and then lowers the drill bit into the workpiece. They can then adjust the depth control to set the depth of the drill, and then press the start button to begin drilling.

Component Description
Base Provides stability and allows drill to be fixed to ground
Column Support for head
Table Provides workpiece with a stable platform
Head Contains motor, drill bit, and controls

Once the drilling is complete, the user can release the depth control and turn off the power to the drill. The pillar drill is a versatile tool that can be used for a variety of tasks, from drilling holes to shaping materials. It is also a very safe tool to use, as it is firmly secured to the ground and the user is able to adjust the depth and speed of the drill.
