What Is A Compound Miter Saw?

A miter saw, often confused with a chop saw, is often the first power saw woodworkers choose for their workshop. With a miter saw you can quickly make repeated cuts at the same length as well as cutting accurate angles. It is important to choose the best compound miter saw for your needs, here we have reviewed the best to help you make a decision.

There are three main types of miter saw; standard, compound, and compound sliding miter saw.

The main difference between a standard miter saw and a compound saw is the ability to perform bevel cuts. A compound sliding miter saw builds on this further with rails for the blade to move along so that it can cut wide pieces of material.

There are Pros and Cons to a compound miter saw over a compound sliding saw as we will discuss further. When choosing a compound miter saw there are many different variations and functions to look out for, we have collected the main points you should keep in mind.

What to keep in mind when picking a miter saw

Saw Safety

Whenever you are choosing a power tool it is essential that it has all the recommended safety functions. A miter saw should always have a top and bottom blade guard, a trigger switch, and a fence to rest your material against whilst cutting.

What is being Cut

An important factor when choosing a miter saw is what you will be cutting. There are various different saw sizes, fence heights, and table sizes to help with different materials and be useful for the various applications.

Cutting angles

A miter saw is perfect for making angle cross-cuts, especially 45-degree cuts. However not all miter saws have the option to rotate a full 45 degrees to both the left and the right. Make sure you check this feature before buying yours.

Where will it be used?

One of the benefits of a miter saw is that they often weigh around 50 pounds. This makes them ideal tools to place in your truck and take to the worksite. However, if you plan to only use it at home you might find a cheaper saw that is slightly heavier.

Our Compound Miter Saw Buyer’s Guide

It is important to understand the common features of a compound miter saw before purchasing. It will fit in perfectly in your workshop alongside your drill press, table saw, and hand tools. Here we have gone over the features to help you find the best compound miter saw for your usage.

Saw Motor

The motors used for miter saws are electric motors. Their power is measured in Amps, so it is important to make sure you have a high enough power for your needs. Most compound miter saws have a 15-amp motor which is more powerful than the average user needs. For most common tasks a 10-amp motor will suffice and might mean you can purchase a cheaper saw.

Cutting Blades

Not only are there different blade diameters depending on the saw you choose, but there are also different types of blades depending on what you are cutting. Areas to consider are the number of teeth on the blade and the depth of the gullet between the teeth. Most of the time you will be fine using a multi-purpose or combo blade.

Blade Guards

As mentioned at the beginning of this guide, safety should be your number one priority when choosing a miter saw. Blade guards are essential both top and bottom of the blade. It is best to select saw with an articulated blade guide. These automatically move out of the way when the blade is lowered for cutting and cover once the blade is lifted.

Positive Stops and laser guides

One of the main uses of a compound miter saw is the quick alignment and cutting of materials. Positive stops help align the saw to commonly used precise points, reducing the time it takes to adjust the saw. A laser guide or guide light is also used to make quick adjustments and help with precision cuts.

Electric Brakes

As well as a blade guard electric brakes are an essential safety feature that rapidly slows down the blade. Once the trigger is released the electric brake reverses the motor stopping the blade in under 2 seconds. There are plenty of other resources with more information on using your miter saw safely.

Fences

Fences are used to support taller material so that it doesn’t rotate or move whilst being cut. You can clamp or push your material up to the rip fence to keep it in place whilst cutting to make sure of a straight cut. These are often able to slide out of the way when not being used.

Dust bags

A clean work area is essential to maintaining good safety practices. A dust bag catches the sawdust as it is blown from the table by the rotation of the blade.

How to maintain a Compound miter saw

Maintenance for a compound miter saw is relatively straight forward as there are few moving parts. The two main areas to keep an eye on are the blade and work area cleanliness.

As previously mentioned it is essential to have a clean working area, free from sawdust and debris. Using either a shop vac or a brush and pan remove the debris throughout the day, making sure to pay special attention to any areas with moving parts.

If you have compressed air in your workshop this can be used to blow the dust away from hard to reach places before being swept up. Be careful not to blow dust further into the motor.

The blade is arguably the most important part of the saw and it is essential to keep it in good condition to provide a good cut. Make sure to remove debris with a brush, not your hands.

If your blade is becoming blunt or disfigured it may be time to replace the blade.

Once you have finished deciding on a compound miter saw you might also be interested in a cordless impact driver to help with jobs around your workshop.

Miter Saw Frequently Asked Questions

What is the difference between a table saw and a miter saw?

Though both saws use a circular blade to make their cuts, they are often used for very different purposes. Compound miter saws can be used for angle cuts and straight cuts while table saws are primarily for straight cuts.

Should I get a sliding miter saw?

There are a few areas to consider when choosing between the two types of sliding and compound miter saws. Cost, size, weight, and range of motion. Sliding miter saws are bigger and heavier, but can cut wider material. They sit on rails which can impede the range of motion. Plus as they have more moving parts a slider will often cost significantly more.
At the end of the day, it really depends on what tasks you see yourself using it for.

10-Inch or 12-Inch Saw Blade?

10-Inch saws are very popular as they will easily cut boards 6 inches wide. This covers you for most materials. 12-Inch miter saws are often more expensive machines due to being larger, also replacement blades are also more expensive.
