Everyone agrees with me:
“Drilling is not a daily routine for each of us if you are not a professional”
We do this often because homework tasks like a photo frame and pictures on the wall require us to participate in the drilling.
However, this process leaves a lot of questions.
Everyone has heard about drilling, boring and reaming. But what does this mean and what’s the difference between them? Is not it enough just to drill a hole?
It turns out that it is not enough.
Knowing the difference between drilling, boring, and reaming makes the task simpler so that you can drill as a drilling master. Why?
Because using different techniques will make a hole for the photos in the wall perfect.
I want to tell you about drilling, boring and reaming separately and show what the difference is.
I’m sure that a small guide will make you a “candidate of drilling sciences.”
What is Drilling?
All people have an idea:
Drilling is the technique or process of creating a hole in a solid or almost solid material.
It is indeed so.
A drill is used to create the hole. It is such a cutting tool that is inserted into the drill chuck.
Drilling occurs due to the rotating mechanism that the drill has. It is this mechanism that cuts the material, creating a hole.
To drill material, you must press on the bit and on the material or part that you are going to drill. Do it with both hands – one hand presses on the drill, and the other – on the part.
There are many options. You can use a hand drill and drill by hand. But you are also free to use an electric drill.
There is a difference between using a manual and electric drill. I and many experts recommend using electric drills only when working with metal, and a hand drill for softer materials, for example, for wood. Why?
Because the electric drill is powerful and has enough power to drill the metal. But this power is too great for working with wood.
It is important to know:
Drilling is not just the creation of a hole in the material.
There are several types of drilling. This can be point drilling, centered drilling, deep drilling, and blind drilling.
The matter is that the point drilling allows the master to make the final hole.
Center drilling is a useful technique for drilling central holes. So, you can make a hole in the center for a turn or for a grid.
A deep type of drilling is the drilling of deep holes, the depth of which is ten times larger than the diameter. Of course, it requires the use of special equipment.
Deaf drilling is the creation of a hole without end, that is, a drill does not pass through the parts.
But this is not the entire list of drilling types. There is also a micro-drilling, vibration drilling, and many other types.
What is Boring?
Boring is also drilling. But it’s drilling larger holes. When can it be necessary?
You already made a hole. But it turned out that you need a hole of a larger diameter. In that case, you can increase the already existing hole with the help of boring.
As a rule, boring follows after drilling.
The reason for this consistency is that boring after drilling provides greater accuracy.
In addition, boring allows you to work with different hole shapes.
What if you need to make a tapered hole? There is a solution – use boring.
This process of creating holes also has several types. This is a boring, boring line, reverse drilling and much more.
For example, line boring is used when the boring bar has support at both ends of the hole. Before line-boring, you should already have a hole.
And what if the boring bar has support only at one end of the hole? Use back boring.
This is a very good type of boring, which allows you to drill through and through blind holes.
For boring, you can use tools such as lathes and jig-burs. The latter is used only for special cases. Lathes are ideal for general use.
What is Reaming?
What do you do when you need to make a hole smooth?
For this, there is a special technique – reaming.
It works so that the drill deploys the hole using rotating cutting tools that cut and smooth holes.
Definitely, the hole must already be ready before you will smooth out the edges of it. So reaming is used by masters only after drilling.
But you must make a hole with a smaller diameter. It is necessary since reaming to increase the diameter when smoothing.
As you already understood the diameter of the drill and the diameter of the dilator is different. It is so because reaming is of different types: a direct expander or expand shells and many others.
If you plan to make a small increase in diameter, then you need to use a straight reaming.
Did you get a hole with a rough edge? Use the pink sweep. In turn, the shell expander is used for the reaming.
There are also tapered reaming, which are designed to create conical smoothing.
You can also use inaccurate precision reaming which clean out burrs and burr holes.
It is an ideal addition to drilling because rarely anyone creates the perfect hole.
Okay, But What is the Difference?
So, we have three drilling techniques. Let’s see what is the difference between them?
One of the main differences is the destination. Drilling is necessary for creating a hole, boring is needed to increase the hole already made and reaming is needed to smooth out the edges of the hole in the final stage.
Thus, each technique has a different task.
Drilling, boring and reaming requires different tools for implementing tasks. Thus, drilling requires the use of a drill, and boring requires a lathe to expand the hole.
Unwinding is a necessary tool when you do ream.
As I said before, the first step in creating holes is drilling. It is important because the other two techniques are designed to work with the finished hole. So, you will not be able to expand the hole, if it does not.
The second step in creating a hole is boring or reaming. Regardless of whether you need to expand the diameter of the hole or not, reaming should be the final stage of drilling, because this should smooth out the edges of the hole.
Therefore, the sequence will be the following: drilling, boring, reaming and always should be such.
Why is consistency important?
When drilling, you use a drill bit. A similar tool works in such a way that it displaces the material while turning. Metal or wood shavings are forced out of the round cavity along the edges of which you receive irregularities and defects.
When drilling, you specify the initial diameter and depth of the hole. For this, you can use a milling machine, lathe, or boring presses. But to create deep holes you need to use specialized equipment.
The second stage is boring, which differs drastically. Here you use a rigid boring bar with a single-point cutter.
Such special equipment makes it possible to control the diameter of the hole to a greater extent. So, the correspondence to the diameter will be more accurate.
This operation is secondary and is used to increase or narrow the existing hole diameter. But this process only works for straight holes.
The third stage is reaming. Here, you smooth out the edges of the enlarged or reduced hole that has already been drilled.
It is logical that the sequence is mandatory for compliance, because drilling is the main operation, and the other two are auxiliary ones.
I believe that now it will be much easier for you to create the ideal hole of the desired diameter and without a single defect on the edges.
Now you know everything about drilling, boring and reaming and the difference between them.
The most important thing is to observe consistency. And if you mistake the drilling with reaming you are unlikely to succeed, then you definitely should not confuse boring and reaming.
It’s easy – first to drill, therefore to increase or decrease and finally make a hole perfect, in which reaming will help you.
Do not confuse also the tools that you need to use for a particular operation.
