What Is a Miter Saw?
In simple terms, you use a miter saw to create crosscuts against the grain, miter cuts — angled cuts — and bevels in a material, which is usually wood.
The purest, and original, form is a wooden or plastic miter box containing 90 and 45-degree slits. You then insert a standard hand saw — pictured below — into it. When your working material is in the box, the slots guide your cuts.
Today, you can still purchase these miter boxes. However, a miter saw usually refers to a powered circular blade saw that drops down onto your working material. This gives rise to their alternative names as drop saws.
Incredibly, it was in 1905 that the Briton, John Abraham Peer, developed the first designs for these tools (1). Although, as it was Ed Niehaus who patented the concept in 1964, historians often credit him with its invention.
When you use a miter, you position the working piece against the saw’s “fences.” The blade falls perpendicular to this surface, creating a 90-degree cutting angle.
However, the main advantage to miters is that you can move the blade to alternative angles — most commonly, 45 degrees. This allows you to make precise angled cuts for bevelling picture frames, baseboards and crown moldings.
Types of Miter Saws
Generally speaking, there are three versions of miter saws available:
These are the most basic of all miter saws. The circular blade pivots, meaning that you can angle it away from the standard 90 degrees. This allows you to make bevel cuts easily.
You can move this blade through the vertical plane to a maximum of 45 degrees. As it will only tilt in one direction, users often refer to them as single compound miter saws.
However, while the blade will pivot sideways, it cannot be moved backward and forward. This limits its usability by restricting the size of material that you can cut. For example, a 10-inch saw will only shear through material 6 inches wide.
- Simple to use.
- Ideal for the beginner.
- Cutting width is restricted.
Sliding compound miter saws are very similar to the standard compound saw. However, there is one main difference: sliding compound miter saws can handle a wider width of timber.
The blade arm is on rails, meaning that you can slide the head backward and forward. This vastly elevates their cutting capacity, allowing you to cope with much wider pieces of material.
- Can handle wide material.
- Allows you to slide through wood instead of chopping.
- Ideal for furniture and vintage baseboards.
- Heavier than standard compounds.
- Rails can restrict extreme cutting angles.
Also known as dual bevel, these tools allow you to angle the circular saw head to either the left or right side.
Most often, although not always, they also incorporate sliding rails. This is particularly useful if you’re completing much decorative trim work, or are having to create intricate bevels. This means that you don’t have to continually flip your working material to cut an identical angle on the opposite side.
- Most versatile miter saw.
- Ideal for intricate work.
- Saves time.
- Premium products mean premium prices.
How to Choose the Best Miter Saws
We know you’re eager to spend your hard-earned dollars on one of the best miter saws. However, you first need to ensure it will meet your exact requirements and serve future needs.
Choosing correctly from the outset means owning a powerful tool that will provide years of satisfying work.
Here are some vital points to consider:
Miter saws typically come in either 10-inch or 12-inch versions.
10-inch blades cost less than the larger variety. The smaller size means that the machine requires fewer amps to run at a sufficient speed. This keeps electricity costs down.
Unless you’re cutting wood wider than 4 inches, there’s little reason to go for the bigger version.
The 12-inch machines are suitable for more substantial board work. Due to the usually higher powered motors, they can cut through thick wood easier than 10-inch versions. This makes them more useful for more hardcore projects, such as laying decking.
Compound or Sliding Compound
Today, many top-end homes contain enormous crown moldings. Furthermore, historical renovations will often require oversized baseboards.
While you can use these expansive materials on a standard compound saw, you’ll need to cut twice, flipping over halfway through. For intermittent work, this may not be an inconvenience. But, if you have a larger or repetitive project, it may prove annoying.
Sliding saws extend cuts to 12–16 inches; more than twice the width of a standard compound, which may be beneficial. Furthermore, as you’re only making one cut, it’ll be more precise and promote a cleaner edge.
Single or Dual (Double) Bevel
If you’re creating intricate bevel and edging work, we suggest opting for a dual bevel saw.
With dual bevel saws, you can tilt the head either left or right. So you can create complex joints and features that, otherwise, would require constant flipping of your board.
If you decide to place your miter saw in a permanent position in your garage or workshop, weight may not be a consideration.
However, it’s another story if you’re moving the machine around a building site. It’s also likely to be stressful if you don’t have the space for a dedicated location. In both cases, you’ll need it to be as transportable as possible.
Factors such as sliding rails, more powerful motors and 12-inch blade capacity will all increase its heft.
These are factory-set points on the miter saw that allow you to quickly select pre-ordained miter cutting angles. This feature increases accuracy and saves you time.
Miter saws can vary in these installed angles. Hence, it’s worth considering whether you’ll require anything more complicated than the standard 45-degree setting.

How to Use the Best Miter Saws
First of all, read the manual!
Ok, we know they can be a little hard-going at times, and it’s tempting just to plug in the saw and get down to some serious cutting. But, understanding the particular aspects of your machine will ensure that you get the best results and reduce any chance of injury.
Hence, here are some general guidelines you should use in conjunction with — not instead of — the manufacturer’s instructions.
Step By Step Guide to Using a Miter Saw
1. Safety First
Protective gear is essential.
We’re talking goggles, gloves, a dust mask and ear defenders, or earplugs. These prevent stray chips from entering your eyes and your lungs sucking in sawdust.
Furthermore, research explains that miter saws emit sound above 100 decibels. The CDC indicates that exposing yourself to this noise level for just 15 minutes could result in hearing loss (4).
Finally, ensure that all necessary guards — as shown in your instructions — are on your machine and fully usable.
2. Marking Up
Mark the board on the area to be cut with a carpenter’s pencil, drawing a line that fully extends across the material you’re working on. Then, place the board on your saw, tightly against the fence.
3. Adjust Angle
If your cut requires an angle or bevel, use your machine’s levers and knobs to adjust to the correct position.
4. Drop the Blade
Lower the circular saw head onto your marking, ensuring it touches. If not, make small adjustments to ensure accuracy.
5. Secure the Material
Once you’re sure you’ve achieved the correct alignment, secure your working material.
At least half of the board’s length should be on your bench for stability. If it’s too long, use an additional bench or miter saw stand. While you can press down on the board to hold (naturally at a safe distance from the blade), a securing clamp is a less dangerous method.
6. SAB — Start, Allow, Bring
- Start the machine with the trigger — ensure it isn’t touching the material you’re about to cut.
- Allow the blade to reach its required speed.
- Bring the saw face slowly downwards to address the board and cut straight through.
When you’ve cut entirely through the board, release the trigger.
Once the blade stops spinning completely, you can then raise the saw again away from your workpiece.
General Tips for Using the Best Miter Saws
- Never lift the blade from your workpiece while still in motion. It may damage the freshly-cut edge.
- Use a heavily-toothed blade — the more teeth, the cleaner the cut.
- Avoid forcing the saw through your board; the blade should carry the workload. Be patient, and drop at a steady pace.
How to Unlock a Miter Saw?
First, check the manufacturer’s instructions for your particular model.
Typically, most modern saws have a knob or pin to prevent the mechanical ankle from moving. You should find this directly behind the blade, close to the center point of the saw’s base. By turning the knob or removing the pin, the head should unlock.
What Size Miter Saw Do You Need?
Miter saw blades come in sizes ranging from the tiny 7.25-inch up to 20-inch, in industrial applications. However, the two most common sizes are 10 and 12-inch.
The size you require depends on your cutting requirements. A 10-inch blade will shear through materials up to 6 inches wide, which is perfectly adequate for most molding and trim boards.
Unsurprisingly, the 12-inch blades will cut larger sizes — up to 7.5 inches. This makes them useful for house projects such as hefty crown moldings. Typically, 12-inch machines come with a stronger motor than the 10-inch to power the blade.
While you can put a 10-inch blade on a 12-inch machine — as long as the arbor holes match — you can’t do the reverse.
What Is a Double Bevel on a Miter Saw?
These saws, sometimes called dual bevels, possess a tilting head that you can angle to either the left or right side. This enables you to bevel in either direction — without having to turn your workpiece over.
What’s the Difference Between a Bevel Cut and a Miter Cut?
Assume you’re making a square picture frame. For the four sides to fit together, you need to cut each length end at an angle of 45 degrees. That’s a miter cut.
However, if you wanted this frame to have angled sides — leading in towards the picture — that’s a bevel cut.
Simply, in the case of miter saws, if the cutting blade is perfectly vertical, it’s a miter. If it’s angled, it’s a bevel.
Making perfect right-angles for baseboards, moldings and joints can be frustrating and tough, unless you use one of the best miter saws. These powerful yet surprisingly simple to use machines make light work of timbers, plastics and composite materials — often at highly affordable prices.
Remember that these tools are here to assist you, so choose one that fits your requirements. If you’re into intricate work, select a dual bevel — dual compound — model. Alternatively, if you’re making furniture or dealing with large crown moldings, opt for a sliding model.
The bottom line is, to make work lighter, use a miter.
