Why Use A Circular Saw Guide?

The circular saw is one of the oldest tools in the world of woodworking. Even if you have something fancy like a table saw, there will still be times when the circular saw can shine.

The biggest advantage that this type of saw holds lies in the teeth, which constantly turn at high speed. On the other hand, other saws rely on the traditional back-and-forth motion.

There are, of course, some drawbacks to circular saws. The prime example of these drawbacks is the lack of precision while cutting.

With the introduction of circular saw guides, you will never have to worry about this issue.

Once you put a circular saw onto the best circular saw guide rail, your cuts are guaranteed to be straight and precise. The rails can also prevent splinters from littering your workshop.

Types of Circular Saw Guide Rails

Currently, there are two types of circular saw guide rails, steel, and aluminum.

circular saw guide rail

Steel Guide Rails

The main advantage that steel guide rails hold over aluminum ones is the fact that they are very durable. These rails can take a whole lot of damage without budging.

However, they get rusty easily, and the weight makes it fairly difficult to control them properly.

Aluminum Guide Rails

Aluminum is among the lightest metals, so guide rails made from it are incredibly lightweight. You can move them easily and quickly.

This material is also not capable of going rusty, so the elegant look will last for a while.

As we have mentioned above, the only con to using aluminum guide rails is their lack of durability. Also, these rails tend to cost a lot more.

Moreover, you also can make a simple DIY fence with metal or wood, even mix both by yourself.

They are often called as rip fences. There are a lot of guides online to build them. But we recommend you should buy one instead of trying to do it.

Structure of Circular Saw Guide Rail System

A guide rail almost always consists of three parts, a base, a fence, and a stopping mechanism.

Between the base and the fence is a small gap where you will run the blade through. The fence will ensure that your saw does not go overboard while cutting.

Below the base is an adjustable stop mechanism that you can use to adjust the cuts.

For instance, if you are looking for a perfect square cut, you can test things out and nudge the stop to change the angle of the cuts.

However, this is basic structure of the guide rail. It can vary between the manufacturer.

Things To Consider When Buy Circular Saw Guide Rail

Choosing the best circular saw guide rail is not as easy as you might believe. There are actually a lot of boxes to check, and here are some of them.

use circular saw guide

Woodworking Style

The first and foremost thing that you need to think about is the type of woodworking you love to do.

For example, if you are a fan of fine and detailed works, then you should avoid deep and long cuts. In other words, the straighter saw tracks will not be good choices.

Some people only use their circular saws for things like lumber ripping. If you are one of them, then a general-purpose circular saw guide rail might not satisfy you. You would need a specialized saw guide for these kinds of operations.

Guide Length

After you have decided on the style, you will need to pay attention to the length of the guides.

The majority of circular saw guides arrive as one piece. However, there are those that are divided into sections. This design choice will provide you with the ability to change the length of the guide.

You should keep the working space in mind whenever you are choosing the length of a guide.

An open work area will allow you to get a much longer guide, as there is no limitation of space. A longer guide can help tremendously in the making of rip cuts.

Guide Width

Most people overlook this characteristic while picking the best circular saw guide rail. However, it does play an imperative role in the grand scheme of things.

If your track is wide enough, you will immediately notice that it is much more stable to cut on.

You may even notice no shaking at all. As a result, your finished product will be much more polished.

Another thing to keep in mind is to ensure that the width must be enough for holding the base plate of your circular saw.

Rubber Grip

Whenever a circular saw works, it will create a strong vibration throughout the table. Your circular saw guide rail will sometimes slip through your hands.

With a good rubber grip, you can guide the saw comfortably through any type of wood. This grip reduces the impact you will feel on your hands, reducing the chance of slipping to a minimum.

Splinter Shield

Splinter is among the most troublesome headaches that a woodworker will have to face. Luckily, manufacturers had foreseen it and came up with a countermeasure: splinter shields.

These devices will stop all splinters from escaping, ensuring that your workspace is as clean as possible.

Materials Used

Each type of material offers a unique balance of weight and durability. In most cases, stronger materials, while weighing more, can survive heavy-duty utilization for a longer time.

The guides lighter in weight are easier to use, but they lack durability. For this reason, it is incredibly easy for them to take damage or wear out.

We advise that you get lighter guide rails if you are new to the world of woodworking. The high gauge aluminum is one of the good options.

Versatility

This aspect is more important for people who just started their woodworking journey. After all, they tend to lack proper funding, so a multi-purpose tool will help them out a lot. They can perform more different cuts.

With a highly versatile circular saw guide, you can turn a circular saw into a track saw or even a jointer.

You are still learning the ropes, so the heavier guides will only confuse you. You also will change the rails fairly quickly, so there is no need for them to be too durable.

Clamping Mechanism

Circular saws have always been one of the dangerous tools, with real risks of injuries looming over their users.

That is precisely why you must pay close attention to the clamping mechanism of your track.

If the track can clamp tightly, it will not move at all during the cutting process. The resulting stability means that there is less of a chance for you to mess up.

With its incredible straight cutting capability, this guide can make your circular saw double as a track saw.

You don’t need to worry about the extension not sticking to the guide properly. Thanks to the utilization of a special 3-point contact system, the guide can stick onto the extension indefinitely.

Tips How To Use Circular Saw Guide

Here are some tips to use a circular saw guide to its best capability.

Edge Tracking

You need to line the track’s edge according to the reference marks you drew beforehand on the workpiece. Only then can you clamp the guide track down and start cutting.

If you fail to do so, your cut will stray away from the correct path, destroying the workpiece.

Guide Sight Locating

Each saw manufacturer has their own approach to making guide sight. As a result, they all have a unique look, but the working principle stays the same.

That is why you can almost always locate the guide sights on the shoe before the blades. They will tell you where the outside edge of the blade would be.

Once you are sure where the guide sights are on your saw, you can line them up with the guide rails correctly. Doing this can ensure that your cut follows the guide rail to a tee.

Guide Placement

You need to keep in mind that the saw blade will always remove some materials.

For this reason, the best solution is to place your track right on top of your workpiece according to length. You should never set it up following your material’s cut-off.

Adding In Support

As circular saw guide rails work just like rulers, they have the same problems that rulers have. One of those is the fact that their precision suffers greatly whenever the surface is not steady.

To ensure that the guide rail is correctly guiding your circular saw, you should put something on top of your workspace.

Our recommendation is to pick either a thick foam piece or rigid insulation sheet.

With this additional support, your material can lie flatly, eliminating any chance of the guide rail being unstable.

There is also another advantage in that it will provide some grip, holding your workpiece in place.
