What the Bosch 12-inch compound miter saw may lack in popularity compared to some of its competitors, it makes up for in quality design and construction. The saw has a heavy-duty 26-inch steel table that extends to 29 inches, and a tall sliding fence for working with crown molding and other large stock. While this isn't the lightest 12-inch saw available, at only 43 pounds it's still plenty portable, and comes with a cushioned top handle for easy carrying to and from the truck. Considering how solid and stable this tool is, and the amount of metal making up the base and table, we were actually surprised to find that it weighs as little as it does. The 15 amp motor on this saw, in typical Bosch fashion, runs remarkably smooth and relatively quiet. The electric brake stops the blade quickly every time. The miter gauge on this saw is engraved, so if the paint wears off you won't lose the markings or need to replace the saw. This is a great feature, and the Bosch saw is one of only a couple of saws on the market that includes it. It also features nine miter detents that can be easily overridden for micro adjustments, and we had no problem getting the table to lock in tight at a half degree off the detent. The saw has a comfortable horizontal D-handle, with a nice wide trigger and a safety switch inset in the handle right where your thumb can reach it. This saw offers all the accuracy and cutting capacity of other 12 inchers in a design that's easy and comfortable to use. Best of all, it comes with the Bosch reputation for solid engineering and smooth performance. The saw comes with a quick-action clamp, a directional dust chute, a dust bag, a 40-tooth carbide blade, and wrenches for adjusting the fence and changing the blade. -- Brian Trinen

Choosing a Miter Saw
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. The type you choose will depend on your woodworking needs.

Basic Miter Saws
Basic miter saws are the least versatile off the three major variations, but they’re a great starting point for novice do-it-yourselfers. These models typically adjust for miter cuts only, so consider upgrading if you need to do more than that.

Compound Miter Saw
Compound miter saws are easier to use than basic miter saws because you can place your stock flat for cutting, and they adjust simultaneously for miter and bevel cuts. A compound miter saw is great for jobs that feature stock that's not very tall or wide, such as door and window trim or picture frames.

Sliding Compound Miter Saws
Sliding compound miter saws are the most versatile of the available models. They have a motor and blade assembly that's mounted on a moveable arm to accommodate longer, wider workpieces. For smaller pieces, the saw performs like an ordinary fixed-head model. On some models, the blade can only pivot in one direction, but on a dual sliding compound miter saw, the blade can tilt to the right or left.

Important Features at a Glance
Though models will vary by manufacturer and design, these are a few of the more commonly found features that you might want to keep in mind.

• Electric brake: Reverses the flow of electricity when the saw's trigger is released. This is an important safety feature that slows the blade quickly in case of emergency.
• Blade guard: Most miter saws have self-retracting guards that withdraw when the saw is lowered for use, and reappear when it is raised.
• Laser guide: Gives a precise visual line where the cut will occur on your workpiece.
• Dust bag: Helps collect sawdust for a clearer, more tidy cutting area.
• Shaft lock: Immobilizes the shaft and blade for quicker, easier blade changes.
• Table extensions: Mount on either side of the saw to help balance longer workpieces.

Miter Saw Blades
Miter saw blades come in a variety of different sizes, grades, and materials, but there are three main types: steel, high-speed steel, and carbide-tipped blades.

• Steel: Inexpensive and good for cutting soft woods or plywoods. Sharpness diminishes quickly in tougher materials.
• High-Speed Steel: More rugged than steel blades, and great for cutting harder woods.
• Carbide-Tipped: More expensive than other blades but much more durable. Maintain sharpness over a longer period.
