The drill's mechanism is actually quite simple: A trigger switch activates an electric motor, which in turn drives a rotating chuck. Numerous accessories can fit into in the chuck, allowing the drill to bore holes, drive screws, and sand, polish, and grind a wide variety of materials .A work table which holds the workpiece rigidly in position. Working principle: The rotating edge of the drill exerts a large force on the workpiece and the hole is generated. The removal of metal in a drilling operation is by shearing and extrusion. There are many different types or configurations of drilling machines, but most drilling machines will fall into four broad categories: upright sensitive, upright, radial, and special purpose.

A radial drilling machine is a cylindrical geared electric drill head that is mounted on an axial armature that can rotate up to its full extent to bore into any substance. The main components are the drill head, column, spindle, and motor. Because it has so many unique movements that make the radial drill machine different from any other drill machine. In fact, a radial arm is the only reason why the machine is called a radial drill. Here is the list of movements of the arm along with benefits: You can rotate the arm 360 degrees around the column. A radial drilling machine has a medium-size column that rotates in conjunction with a motor. The drill bit is mounted on a radial arm. The rotary head contains a gearbox, motor, spindle, and a control panel. The operator can adjust the speed and feed the workpiece manually.
