Here are the basics types of drilling operations that you can perform with any drill machine.
Drilling: This 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 is used for enlarging a hole that has already been drilled. It can also be used to cut a tapered hole.
Reaming: This operation is used when you want to give finishing to the internal surface of a hole that has been made already.
Counter boring: Counter boring 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 tapping.
So that covers all the major types of drilling operations that can be performed in a drilling machine. I’ll see you in the next blog post.
