12-inch compound miter saw with a laser cutline guide, extension rails, and a 15 Amp motor (4,500 RPM). It includes integrated carrying handles and a dust bag, and provides positive stops for common miter angles. Designed for general woodworking and DIY cutting tasks.

Skil 12 IN. Quick Mount Compound Miter Saw with Laser Review
I spent a couple of weekends trimming a room and knocking out a few shop fixtures with Skil’s 12-in miter saw, and it proved to be a straightforward, capable companion for general DIY and light woodworking. It’s not a sliding saw and it doesn’t pretend to be a pro trim rig, but there’s a lot here to like if you value simple operation, predictable angles, and an easy setup.
Setup and First Impressions
Out of the box, the saw needed the usual attention: squaring the blade to the fence, checking the bevel stop at 0°, and verifying the miter detents. My sample arrived close but not perfect. Ten minutes with a square and hex key had the fence aligned and the bevel stop set. The miter gauge’s detents locked crisply at the common angles (0, 15, 22.5, 31.6, 45 degrees), which I appreciate when bouncing between casing and crown profiles.
The integrated carrying handles make it easy to lift the 42.5-pound unit onto a bench without contortions. At that weight, it’s stable during cuts yet still portable enough to stash between projects. The 6-foot power cord is serviceable; I kept an extension cord handy for room-scale trim work.
Build and Ergonomics
Switchgear and knobs feel solid for the class. The miter lock is intuitive and the detent override is easy to use when you need an off-angle cut. The bevel mechanism only tilts to the left up to 47°, and there’s no bevel to the right. That’s fine for most casings and baseboards, but mirrored bevel cuts take a touch more thinking (or you have to flip the workpiece). If you do a lot of symmetric crown with nested cuts, a dual-bevel saw is more convenient.
The table extension rails are simple but handy; they support longer stock without dragging, though I still recommend a stand or roller support for anything over a few feet. The electric brake stops the blade promptly after the trigger—one of those features you don’t appreciate until you’ve used saws without it.
Cutting Performance
The 15-amp motor spinning at 4,500 RPM is reasonably powerful. On 2x stock and pine casing, the saw stayed confident with no bogging. I also ran it through oak and maple trim; with a slower feed, it maintained line and finish acceptably. It will technically crosscut wider material than a 10-in non-slider, but remember this isn’t a sliding design. Expect straightforward, one-and-done crosscuts on 2x6 and most casing and baseboard. Wider shelves and stair treads are where you’d want a slider.
The max cutting thickness is 3.5 inches, which means a true 4x4 requires a flip cut—common for 12-in non-sliders. The arbor is a standard 5/8-inch, so upgrading blades is easy. The stock blade is fine for construction lumber and rougher carpentry. For trim work, I swapped to a 60–80T blade and immediately got cleaner shoulders and less tear-out on veneered stock.
Accuracy and the Laser
Out of the gate, my 90-degree crosscuts were square enough for framing and finish carpentry. After calibration, I measured 0.1–0.2° deviation on repeated 45° cuts, which is within tolerance for most base and casing joints; a little sanding buzzed away the difference. The nine positive stops make it quick to hit common trim angles, and they hold firmly without the subtle “click past” you sometimes get on budget miter saws.
The laser cutline is helpful as a reference line, especially for rough layout. It’s bright indoors but fades outdoors in full sun. Like most laser systems, it aligns to one side of the kerf, so you need to calibrate and then be consistent about which side of the line you keep. For exacting work, I still rely on a fine pencil line and a test cut, but the laser speeds up repetitive cuts and reduces guesswork. If you’re used to shadow-line LED systems, this laser isn’t as precise, but it’s a welcome guide.
Dust Collection
The included dust bag is functional in the most basic sense; it will catch some chips from straight crosscuts but misses plenty during bevels and miters. Hooking up a shop vac dramatically improves capture. I used a universal rubber adapter to fit my 1-1/4-inch hose, and collection went from “messy but manageable” to “I’m not sweeping the whole shop.” As with most miter saws in this class, don’t expect cabinet-saw cleanliness.
Noise, Vibration, and Feel
Noise levels are typical for a 15-amp miter saw—hearing protection is a must. Vibration is well controlled when the saw is bolted down or clamped to a bench. The trigger response is predictable, and the blade guard cycles smoothly without hanging up on wider stock.
Portability and Jobsite Use
At 42.5 pounds with integrated handles, this saw is realistic to carry room to room or onto a small jobsite. The footprint is compact enough for a miter stand or a sawhorse/plywood setup. If you travel with tools frequently, the weight is a trade-off for the 12-inch capacity; for strictly punch-list trim, a lighter 10-inch might be kinder to your back.
Limitations and Things to Know
- Single bevel, left only: Efficient for most tasks, but mirrored bevels take extra steps.
- Non-sliding head: Limits crosscut capacity on wider boards and shelving.
- Laser is a guide, not a guarantee: Calibrate it and use it as a quick reference, not a substitute for marking accurately.
- Dust collection is basic: Plan on a vac if you’re working indoors.
- Cord length: Six feet feels short in a room—an extension cord solves it.
I’d also keep expectations in line with duty cycle. The motor is strong enough for weekend projects and even a busy day of cutting trim. If you’re ripping through hundreds of cuts of dense hardwood every day, a heavier-duty or brushless pro saw will hold up better long term.
Tips for Best Results
- Upgrade the blade for finish work; a higher-tooth-count blade improves cut quality dramatically.
- Calibrate the fence, bevel, and laser before your first project and after any bumps in transport.
- Use stop blocks for repeatable lengths and better productivity on trim runs.
- Add outfeed or a miter stand when cutting longer stock; the extension rails help, but they’re not a full support solution.
- Hook up a shop vac with an adapter to tame dust and keep your lines visible.
Who It’s For
This saw makes the most sense for homeowners, DIYers, and woodworkers who need a reliable, easy-to-use miter saw for trim, small furniture parts, and general project work. It’s also a good fit as a secondary shop saw for quick crosscuts when you don’t want to set up a slider. If you regularly tackle wide shelving, large crown profiles, or complex compound work, you’ll feel the limitations of the non-sliding head and single bevel.
The Bottom Line and Recommendation
Skil’s 12-in miter saw hits the right notes for its class: a capable 15-amp motor, crisp miter detents, a useful (if not perfect) laser, and friendly ergonomics anchored by an effective electric brake. It’s easy to set up, holds adjustments, and produces accurate cuts after a short tune-up. The compromises—single bevel, non-sliding capacity, modest dust collection—are predictable at this level and manageable with technique and accessories.
I recommend this saw for DIYers and budget-conscious woodworkers who want a straightforward, dependable tool for trim and general cutting without the complexity or cost of a sliding dual-bevel saw. It rewards a bit of setup and a blade upgrade with accuracy and speed that will serve most home projects well. If you need broader capacity or mirrored bevel convenience, step up to a slider or dual-bevel model; otherwise, this is a solid, user-friendly choice that earns its keep.
