The drilling machine is one of the most vital tools. It has transformed a lot of complex manufacturing processes into very simple tasks. It is an important tool that is used in several industrial and commercial operations; such as construction, woodworking, metalworking etc.
It is also commonly known as a drill press. It is basically used for drilling holes of various sizes as per required depths on any surface area. Moreover it is utilized for tapping, reaming, counter boring, countersinking, spot facing etc.
There are several categories of it such as the upright, radial and special purpose drilling tools. Even though all these are execute the fundamental drilling task; there are certain specific objectives and additional features that can be done more precisely and easily.
A radial drilling machine has a drilling head, which is mounted to slide along a radial arm; and can be rotated, raised or lowered, on a vertical mast to adjust the position of the drill above the work piece. It is used for numerous functions that include drilling, reaming, boring, tapping, counter boring, lapping, screwing and spot facing. These are capable of drilling a wide range of materials made from cast iron, steel, plastic etc.
The latest range includes V belt driven radial drill and all geared radial drill; as well as the imported radial drill machines. These are normally categorized on the basis of the arm length and the width of the drill bit swing.
The plain radial drilling always has a vertical spindle that may not move over the work piece. In the half universal drilling the spindle can be swung in one place over the work piece. A full universal drilling machine offers a great amount of flexibility. It has the capability to move and swing in any plane and over any angle; without moving the work piece.
It is a highly versatile workshop tool. The drilling spindle is attached to the end of an arm. Hence it can hold large sized work pieces, depending on the length of the arm. Whereas in the other types of drilling machines; only smaller work pieces can be placed under the drill.
Further, the arms of these radial drilling can be moved and swung in various angles to reach the exact drilling locations. The extra ability to move the arm extensively; permits even larger work pieces to be placed quite easily. It can also be used as a tool for placing fasteners. It can cut through the material and at the same time fasten two pieces of materials together with some type of fastener.
Nowadays many radial drilling manufacturers supply sturdy, accurate and long lasting radial drill machines in the local and global markets at competitive rates.
