The qualification proposed the role of people who work as drillers and perform different tasks that involves a broad range of skill-based applications which are applied in various contexts that involve the application of judgement and discretion in the process of selection of tools, services, equipment and other contingency measures. There are no licensing, regulatory, certification and regulatory requirements for the application process to the given qualification at the publication time. There are no other regulatory or licensing requirements to the course qualification. The operations in drilling activities include the cutting process for the application of drill bit for cutting a hole of the circular shaped cross-section in solid materials. The drilling process generally uses a tool that has rotary motion and called a rotary cutting tool in general has multiple points.

The packaging rules include the following sections:

  1. Core units: There is a total number of 8 core units in the course that are strictly mandatory to learn and make its necessary submission of the documents such as assessments and assignments.
  2. Elective units: The elective units in which the student shows his or her interests must follow the guidelines and following it must select the units that seem more relevant to the core units.

The operations in drilling activities include the cutting process for the application of drill bit for cutting a hole of the circular shaped cross-section in solid materials. The drilling process generally uses a tool that has rotary motion and called a rotary cutting tool in general has multiple points. The part is pushed against the piece that is in the application and further rotated at different rates from hundreds to thousands of revolutionary motions per minute. The forces that are responsible for cutting edge against the piece, chopping off chips which are also known as swarf from the hole in the process of drilling. In rock drilling, the circular motion is not used for the creation of hole. The hole is prepared by the process called hammering a drill projected into the hole with quick repeating short motions and movements. The hammering activity can be run from an external source to the top of a hill or in the hole. Drills take parts in the actions of drilling carried out horizontally and are called drifter drills. In very special cases there have been special-shaped drilling bits designed that are used to cut down holes of cross-section found in non-circular shape possibly a square cross-section is found.

The drilling process affects the properties found mechanically belonging to the workspace by forming low residual stresses surrounding the whole opening area and also the place which has a very thin layer of highly disturbed and stressed material on the freshly formed surface. There are many reasons to cause the workplace more susceptible to acquire crack propagation and corrosion at the surface. The characterization of drilled holes is done by watching out its sharp ends on the entering side and further presence of burrs on the finishing line and side. The interior part of the hole consists of helical feed marks. The drilling process majorly affects the mechanical properties of the tool used in the workplace by forming low stresses near the opening area which also has a thin layer and high stress. Spot drilling is the process of drilling a hole that is targeted as a guide for the process of drilling the end hole.

A Centre drill is known to be a two-faced tool that contains a twist drill with a degree of 60-degree countersink that is used in centre holes in a workplace designated to be mounted among the centres for grinding or turning.
