If you need to crosscut lumber, trim, or molding at precise angles, a miter saw is the tool for the job. We compare models from DeWalt, Milwaukee, Makita, Bosch, Ryobi, and Craftsman using manufacturer specs and real user reviews. A 10-inch saw covers general framing. A 12-inch handles crown molding. A sliding compound model takes on architectural trim. This page breaks down blade diameter, bevel type, and the features that actually matter so you can pick the right one.
A miter saw is a stationary tool with a spinning blade that drops vertically to crosscut lumber. It cuts at 90 degrees and at angles (miters) up to 45 degrees left and right. Blade diameter, either 10 or 12 inches, determines the maximum width you can cut in a single pass. A 10-inch blade cuts about 5.5 inches wide. A 12-inch blade cuts 8 to 9 inches wide, which is what you need for crown molding and baseboards.
Three types exist. Standard saws have a blade that stays in place. Sliding saws extend on rails for wider crosscuts. Compound saws tilt the blade for angled cuts. Nearly every modern saw is compound, giving you both miter and bevel capability, though some budget models skip the bevel. Dual-bevel compound saws tilt both left and right so you never have to flip the workpiece.
Pay attention to bevel type (single vs. dual), crosscut capacity in inches, spindle lock and electric brake for safety, laser or shadow line for accuracy, dust collection, and fence quality. Weight matters too if you move between job sites.
We break down specific models with specs, prices, and trade-offs in our best miter saws guide.
A 10-inch blade crosscuts up to 5.5 inches wide at 90 degrees, which covers framing and general carpentry. A 12-inch blade cuts 8 to 9 inches wide and handles crown molding, baseboards, and wider trim. A 14-inch sliding saw gives you both blade size and extended reach. For residential trim and finish work, 12-inch is the sweet spot. Framing crews cutting dimensional lumber can get by with 10-inch and save weight on transport.
Miter saws run 3,000 to 5,000 RPM at no-load. Higher RPM (5,000+) produces cleaner cuts in hardwood and cross-grain lumber. Lower RPM (3,000 to 4,000) generates less heat and works better for thick material. Corded saws hold RPM more consistently under sustained cutting. Cordless models can drop RPM when you push through hardwood.
Crosscut capacity is the widest cut you can make in one pass at 90 degrees. A 10-inch standard (non-sliding) saw gets you about 5.5 inches. Add sliding rails and that same 10-inch blade reaches 9 to 10 inches. A 12-inch standard cuts 8 inches; a 12-inch slider does 12 inches or more. Measure your widest workpiece before buying.
A single-bevel saw tilts left only. You flip the workpiece for right-side bevels. A dual-bevel tilts both directions and eliminates the flipping. On symmetrical molding like crown and baseboards, dual-bevel saves you real time. Single-bevel costs less but requires more handling. If you do high-volume trim, dual-bevel is worth the extra $100–200.
Standard 10-inch saws weigh 35 to 50 lbs. A 12-inch model runs 50 to 70 lbs. Sliding rails add another 10 to 20 lbs. If you move between job sites, a 35 to 40 lb saw is noticeably easier to carry. Heavier saws (60+ lbs) give you more stability and usually better dust collection, so think about where yours will actually live.
Corded (120V) saws plug in and never run out of juice. Cordless (18V/20V Li-ion) skip the cord entirely, which is the whole point on remote job sites. You get 40 to 90 minutes per battery on cordless. Corded costs less and wins for long cutting sessions. Cordless wins for setup speed and portability.
A 10-inch blade crosscuts lumber up to 5.5 inches wide at 90 degrees. A 12-inch blade cuts up to 8 inches wide, which matters once you get into crown molding, baseboards, or thicker stock. DIY and residential work rarely needs more than a 10-inch saw. Go with 12-inch if you are doing crown molding, deck railing, or trim-heavy projects. Pros overwhelmingly pick 12-inch for the extra reach.
A single-bevel saw tilts left only. You have to flip the workpiece for right-side bevels. A dual-bevel tilts both directions, so you skip the flipping and save real time on framing and trim. Single-bevel runs $50–100 cheaper. If you are doing high-volume trim work, dual-bevel saves 10–20% of your cutting time, and that adds up fast.
The blade extends forward on rails, which gives you a wider crosscut. A 10-inch slider cuts nearly as wide as a 12-inch standard saw. You will pay $100–200 more and carry extra weight. If you cut crown molding or wide trim regularly, sliding pays for itself. For general framing and shorter stock, a standard saw does the job and costs less.
Corded (120V) saws plug in and deliver consistent power for hours. Cordless (18V/20V Li-ion) give you portability, which matters on job sites without nearby outlets. Expect 40–90 minutes per battery depending on blade size and material. Corded costs less and never runs out of power. Cordless sets up faster when you are working remote.
A compound saw combines a miter cut (left-right angle) with a bevel cut (tilt). Nearly every miter saw on the market tilts, so they are technically compound already. A dual-bevel compound tilts both left and right. You need compound capability for stair stringers, molding with beveled edges, and architectural trim. Make sure your saw tilts at least 45 degrees in each direction.
Laser guides project a line showing where the blade will cut. They are a useful visual reference but less precise than a good fence. Some models have wobble in the laser. For production trim work, the convenience is real. For precision cuts, always verify on scrap first. A lot of pros skip the laser entirely and rely on the fence and blade kerf marks.
Start with an electric brake (stops the blade within 3 seconds) and a blade guard covering the top. A spindle lock prevents accidental starts. Shadow lines mark the cut path without needing a laser. You want a tall fence to keep your hands away from the blade, and stay away from models with exposed carbide tips. Dust collection matters more than people think; good collection cuts down on respiratory irritation. Adjustable fence stops also help prevent kickback.
