Chain saw bar:

To begin with, we will tell you that a chain saw a bar is a tool used in carpentry. Its main job is cutting. It cuts through logs and sheets. Since it is a hand tool, so you can carry it anywhere.

The advantage of its cuts is that they are mighty. They can make their way through rigid objects as their teeth are powered by a chain that moves on a chain bar.

Applications in daily life:

It has broad applications in woodworking tasks. You can conveniently use it for cutting down trees from their trunks, making cuts during firebreaks for putting off the fire, limbing.

It is a real hard worker! It will help you break down concrete sleds, it pierces through rock wooden snow bars, you can shape it by using a chain saw bar.

Parts of the chain saw bar:

It has many parts that include the engine, diving mechanics comprising of the centrifugal clutch, and sprocket. A guide bar is our main interesting part having a gauge, oil holes, grease holes, and guide slot. A cutting chain is made up of riveted small sharp teeth for cutting.

Identity holding components of the chain saw bar:

The primary power supply for this is provided by its engine. Of course, more powerful the engine, more significant is the outcome!

Now we will guide you about its identity trademarks. There are many types of chains available in the market. But the irony of fate is, each saw has its identity marks to distinguish from others.

You must be anxious to know that does the chain saw bars have fingerprints? Well, it has its specification with the help of three numbers. Let us know a bit about each of these magical figures.

They are pitch, gauge, and several drive links and bar length.


This is very crucial. It is the chain size with the matching bar. It is usually taken as a round figure of the actual.
You can see pyramid-shaped rivets along the chain.

It is recorded by taking a measuring tape. Take the length of three consecutive hooks and divide it by two. This is recorded too.


It is the measurement of the width of the drive links found on the chain of chain saw bar. This width is so important because it determines the fitting your chain needs to get fixed in the chain grooves.

So, if you don’t take their perfect size, the drive links in the groove will either lie down loosely if small and if too large won’t move in the groove even.

Taking the size of the gauge is easy too. For this, you have to be rich enough to hold penny, dimes and a quarter. You will put as many in the groove as may fit in.

One quarter, penny and dime will have the following measurements, respectively, 0.063, 0.058, and 0.050. Add them if more than one snuggles in.

Drive links:

Of course, it is pivotal too. It tells you the number of segments a bar chain that your chain has. Understand its significance from the fact that if the total number is more, it won’t fit. And if it is less, again, that would be a headache!

How are you going to count them accurately? You can do this by two methods. One is direct, where you mark anyone to link with a marking tape and count each drive link individually until you reach the one you marked with a tape.

Write down the reading on some paper. There is another indirect method. Put your chain on the table in a way that two drive links lie side by side.

Start from one end and keep counting till you reach the other. Either count in twos or multiply the end reading by 2. Note it down. Here you go! So simple and easy peasy lemon squeezy!

Bar length:

It provides the cutting length. What is the cutting length? It is the length of the saw from the tip to the part touching the base.

It is measured by turning off the chainsaw. Put the saw in a way that side with bolts is facing upwards. Take the measuring tape.

Measure from the tip of the nose to the base. Record your reading. Now round it off to the nearest even number. This is not required during chain purchase.
