Introduction to Radial Drilling Machines

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. This type of equipment is also referred to as a rotary vane pump as it rotates using an inner cylinder that contains a rotor, an impeller, and a stator. This type of machine has two main types; a vertical radial drill and a horizontal radial drill.

Working Principle & Components of Radial Drilling Machine

The working principle of a radial drilling machine is similar to that of a drill press. The only difference is that the drilling work lies on a vertical plane, hence the term ‘radial’ and the location on the bore being called ‘vertical’. The inner cylinder rotates on a vertical axis, but because of the nature of the shaft and the working principle, the work does not lie on a horizontal plane. This is known as ‘firing’ work. The inner vane rotates to move the drill bit to the desired location and a discharge happens when the shaft reaches its perpendicular position.

Another important component of a radial drilling machine is the column. These columns are designed for maximum performance with maximum torque. There are three types of column available in the market; an eccentric, a centrovertical, and a horizontal casing. The eccentric and centrovertical columns are known for their maximum performance.

The spindle or the rotary shaft is the core of a radial drilling machine. It is the most important part of the machine and is constructed from brass, steel, or even other materials to suit the application. Spindles are available in various shapes and sizes to ensure the optimum performance of the machine. Some of the more popular types of spindles include; ball, tapered, double-ended, single-ended and jack-knifed. These all are fitted with locking levers to prevent accidental changes in direction while drilling. The depth gauges are fixed into the spindle and help in measuring the exact depth of the hole during the drilling operation.

Important Information Related to Using Radial Drilling Machine

To operate the radial drilling machine safely, it should be well maintained and its alignment maintained at all times. The tool and work piece should be aligned properly so that there are no chances of unintended repositioning of the workpieces while drilling. The radial drill heads should be checked often for cracks and elongated holes as these could cause sudden depressions in the surface of the material drilled. These depressions could lead to corrosion of the drill heads and cause premature failure of the machine.

The drilling head on a radial machine is normally mounted above the work piece and extends outward. The spindle and drill bed of the machine are placed above the belt; the two sections of the spindle work in tandem to allow for rotation. A trolley or crane is used to transport the spindle and the work piece from the truck to the location to be drilled. To reduce fatigue wear and increase efficiency, the radial drill is usually equipped with ball bearings. The drill heads may be manually adjusted using knobs and levers; radial drill machines usually have variable-speed motors to give the user the option of selecting the right power level.

  • Radial Arm – In radial drilling machine, the radial arm holds and supports the drill head assembly and can be moved around on the extent of its length.
  • Column – Column is the part of the radial arm drill press which holds the radial arm. It fixes itself and the radial arm to the base and allows seamless movement of the arm.
  • Elevating Screw – Elevating screw is a piece of metal with screw-like circular thread. It helps in adjusting the vertical height of the radial arm by raising or lowering it.
  • On/Off Button – This button has a simple function of activating or deactivating the drill press.
  • Arm Clamp – Arm Clamp provides support and holds both, the column and the radial arm.
  • Table – Table is the part of the machine placed just below the radial arm. It is where the workpieces are fixed and worked on. This component and be raised, lowered or rotated in order to facilitate the drilling process.
  • Base – This part is fixed to the ground and is directly attached to the table and the column. This way it provides support to the whole mechanism.
  • Spindle – This part is attached at the mouth of the radial arm. It is the rotating part of the drill press and holds the drill head.
  • Drill Head – Drill head is the part of the drill press that penetrates through the material or workpiece. It is attached to the radial arm by the spindle.

Working: The workpiece is fixed on the table. Height and reach of the radial arm are adjusted before starting the drilling process. Once everything is arranged, the drill is turned on and the drill chuck is lowered with help of a radial drill. The hole is generated in a workpiece by exerting large force via drill head as it is lowered. This large force is resultant of high-speed rotation drill head. The drilling of hole and removal of metal is resultant of shearing and extrusion.


Radial drill machine is an efficient and easy-to-use machine. There are a number of advantages of using the radial arm drill press. One of these advantages is that radial is free to move around during drill. This flexible movement provides a large amount of area that it can cover which is only dependent on the length of the arm. Another advantage is the high rate of production that it allows since the arm can actually swivel out of the working area allowing cranes and derricks to quickly place workpieces on the table.

The Radial Drill and Lathe Machine Have Made Immense Contribution to Manufacturing

The machine tools used in industry can be classified into various categories. The basis of classification for machine tools can be done as follows.

  • Classification based method which the metal is shaped. This includes metal cutting equipments and metal forming tools.
  • Classification based on control of tool movement, where we get the difference between convectional models and CNC machines.
  • Classification based on applications of the machines. In this group we have the general purpose machines and the special purpose lathe machines.

The metal cutting machines comprise the bulk of the demand for the machine tools. Some of the major metal cutting machines include the radial drill machine and the lathe machines.

The Radial Drilling Process

This is the process of cutting holes through metal and uses a drilling machine. Fine metal shavings are forces out of the metal as the drill bit advances inside metal in rotating motion. The radial drill machine comprises of the drilling head mounted to slide on a radial arm, which is designed in a way that it can rotate, be raised or lowered on a vertical axis depending on the positioning of the work piece. The main feature is therefore the ability to swing horizontally around the arm and vertical for height adjustment.

The machine is designed for medium, large and heavy work pieces and therefore designed with rigid frame and base to be able to handle and accommodate heavier work pieces. In industry, there are various designs of the radial drill machine and these are;

The Plain Radial Drill Machine

The arm has vertical and horizontal movement of drilling head on the arm and circular movement of the arm along the vertical axis.

Semi Universal

In addition to the movements of the plain radial drill, the drilling head can be swung perpendicular to the horizontal arm. This allows drilling at an angle to the horizontal plane.

Universal Radial Drill

In addition to the above movements, the arm holding drill head can be swung horizontally. These innovations enable the machine to drill at any point and any angle.

The Lathe Machine

The lathe machine is also among the important tool room equipment used in metal shaping and sizing.  It is designed to hold the work piece for various metal operations to be done. These include turning, grooving, chamfering, knurling, facing and other forming operations. The lathe machines are classified heavy duty, light duty, medium duty lathe machine.

Heavy duty lathe machines are designed with special mechanical features that enable it handle the heavy thrust and forces required during metal shaping. The machines are also designed to operate with minimal vibration. This is achieved through use of close grained cast iron combined with salt additives to achieve the required hardness.

Light duty lathe machines are used in applications such as wood working and lighter applications of turning, tapering, slotting, metal spinning and other smaller scale applications. Lathe machines are made with robust construction to guarantee perfect metal shaping and long functional life.

Due to such kinds of operations, the radial drill and lathe machines are the focus of machine tooling, with huge amounts of resources spent on development and innovations on these machines.
