7 Different Types of Drilling Operations - Maan Technoplus

This blog post will help you learn about different types of drilling operations performed in drilling machines.

The best part?

We have also included pictures of each type of drilling operation so that you can easily identify them.

So without further ado, let’s get started…

What Is Drilling Operation?

A drilling operation is a cutting process that people use to cut a hole in a workpiece by using a drilling machine.

Why Is Drilling Operation Important?

There are many techniques available for producing holes in a workpiece. But when you want to produce round holes in a large number of workpieces in less time, it is cheaper and quicker to perform drilling operations by using a drill machine.

Types of Drilling Operation Performed in Drilling Machine

Here are the basics types of drilling operations that you can perform with a drill machine:

1. Drilling
2. Boring
3. Reaming
4. Counterboring
5. Countersinking
6. Spot facing
7. Tapping

Now let’s explore each drilling operation in brief.

Drilling

Drilling operation is used when you want to create a hole in any workpiece for the first time. This is the most basic and widely used operation of all the others.

Boring 

Boring operation is used for enlarging a hole that has already been drilled. It can also be used to cut a tapered hole.

Reaming 

Reaming operation is used when you want to give finishing to the internal surface of a hole that has been made already.

Counterboring 

Counterboring operation is often needed to recess kept screws in parts. A counterbore machined after drilling has taken place and creates a larger diameter along the same axis as the hole that was drilled previously.

Countersinking 

Countersinking is a machining operation used for making a conical hole cut at the end of a hole. This machining operation is used commonly when something like a screw is to be fitted in the hole.

Spot facing 

Spot facing is the operation of making the surface of the workpiece smooth and flat. So that it can provide a good seat for a nut or a washer.

Tapping

The process of producing threads with the help of a tapping tool in a hole made inside a part is called the tapping operation.
