Miter saws are versatile tools that have become a mainstay of workshops everywhere. These powerful saws make angled cuts by pulling a circular blade down onto a workpiece with a short, controlled plunge. It might appear that miter saws are infinitely complex and varied, but there are only three general types: basic miter saw, compound miter saw, and sliding compound miter saw. The type you choose will depend on your woodworking needs.

The Motorized Revolution

It wasn't that long ago that making accurate crosscuts in wood required a skilled hand, a sharp handsaw, and a chunk of time. But in the early 1970s, a new saw began to appear on job sites that promised to speed up these cuts: the motorized miter saw, or chop saw. A chop saw is essentially a lightweight circular saw mounted on a spring-loaded pivoting arm supported by a metal base. While these relatively small, inexpensive saws don't have the cutting capacity of a radial arm saw, they are very portable and rugged enough to stand up to daily use (and abuse) on the job and survive the pickup truck ride to the next job.

» Steel detent plate and pin provide repeatable pinpoint accuracy
» Cuts up to 6" base horizontally
» 0-to-50 degree right and left miter, 0-to-48 degree bevel capacity
» 11 positive miter stops for quick setting to most common angles
» Tall sliding fence supports up to 4-1/2" crown molding vertically nested

Chop Saw Cutting Capacity

A chop saw with a 10-inch blade and a hefty 12 to 15 amp motor can make quick, accurate 90-degree cuts in two-by-fours and two-by-sixes. If you rotate the blade left or right, they can also make miter cuts, and some of them can be pivoted past 45 degrees in one or both directions. But 10-inch chop saws have one major limitation: cutting capacity. Most of them are limited to about a 5 1/2-inch cut at 90 degrees, and even less when cutting miters.

DeWalt DW706 12 inch Double Bevel Compound Miter Saw

» Cuts left and right miters in 6-inch base held vertically against the fence
» Easily portable at 44 pounds
» Double bevel allows you to flip the blade, not the material
» 11 positive miter stops deliver quick setting to most common angles
» Tall sliding fence supports up to 6-5/8-inch crown molding vertically nested

For this reason, manufacturers also offer chop saws with 12-inch, 14-inch, and even 15-inch diameter blades, which enables them to make cuts that are wider (up to about 7 1/2 inches) and higher (up to about 3 1/2 inches). For some users, this capacity still isn't enough, which is why the pricier--but more versatile--sliding compound miter saws have become so popular. In fact, regular chop saws are disappearing from the marketplace.

Compound Miter Saws and Fences

Chop saws that can make bevel cuts as well as miter cuts (and most of them can nowadays) are technically called compound miter saws . If you tilt the blade while cutting at an angle, these saws can cut crown molding while the stock lies flat on the table. But tilting the blade means that the fence has to get out of the blade's way when the saw head heels over. To achieve this, some manufacturers significantly reduce the height of their fences near the blade, then advise users to add a supplemental wood fence when making regular cuts that need extra-height support. But a better approach is to use a sliding fence, which provides full-height support and moves out of the way for bevel cuts.

Miter Matters

Preset detent positions on the saw's turntable (typically set at 0, 15, 22.5, 30, and 45 degrees) help to position the blade quickly and accurately for common miter cuts. Some manufacturers also offer detents for the common crown molding angles on the miter and bevel scales. But the detents on some saws can be tricky to override if you want to make minute adjustments to the fit of a cut--say, a 32.25-degree miter instead of the 31.62 degrees that crown molding typically requires. The miter and bevel scales offered by different manufacturers aren't equally easy to read, either. This is particularly true of bevel scales, which are often partially hidden behind the body of the saw.

Before You Buy

The points below should help you choose a compound miter saw that will suit your needs:

Weight: If you do a lot of moving around, weight can be an important factor. Some saws weigh as little as 30 pounds, while heavier saws can weigh in at 50 pounds or more.
Handle comfort: Some saws are more balanced than others when you pick them up by their carrying handle. The position of the trigger handle may also affect how comfortable the saw is to operate. Many people prefer D-shaped handles oriented perpendicular to the blade.
Saw blade: Most saws come equipped with a carbide-toothed saw blade as standard equipment. If the saw comes with an inexpensive steel blade, you'll want to replace it with a higher-quality blade, specifically designed for a miter saw, for consistently smooth, straight cuts.
Blade guard: It's easier to see the cut line if your saw has a smoothly operating blade guard that automatically moves out of the way as the blade nears the cut, as opposed to being pushed out of the way by the workpiece.
Accessories: Finally, accessories such as dust bags, table extensions, and stock clamps often are included with the price of the saw, but not always. Remember to add them to your calculations if you need to purchase them separately, since they can have a considerable effect on your total cost.
