Mitre saws

Mitre Saws for Trim, Framing, and Finish Carpentry

A mitre saw is used to cut the same angle 100 times as cleanly as the first time. Finish carpenters rely on it for baseboard, casing, and crown, where a half-degree error shows up as a gap at the corners. When framers cut studs, joists, and rafters to length, they focus more on speed and capacity. The saws in this collection are miter saws that can handle both types of work. Blades come in a variety of sizes from 6 ½ to 12” and with cords or batteries, and the stand and dust bag complete the package.

Compound, Sliding and Double Bevel Mitre Saws

A compound mitre saw swings left and right for mitre cuts, and tilts for bevel cuts, thus enabling both to be made in one pass. You'll need this for crown molding, hip rafters, and picture frames. Most models feature a +0, +22.5, and +45-degree stopping positions. Many also include crown detents at 31.6 degrees mitre and 33.9 degrees bevel (which is for the standard 52/38 crown cut flat on the table).

A mitre saw with a sliding head is used to add rails, to allow the head to move forward and back through the mitre. The maximum size that can be cut with a fixed 10" saw is approximately a 2x6. The 10-inch slider cuts boards that are nearly 12 inches wide. However, the trade-off is space - rails require rear clearance, so plan for it when you're building a small room or trailer. Articulating-arm saws overcome this issue by moving the head on a hinged arm rather than rails, which lets you push the saw much closer to a wall.

Double bevel saws bevel to both sides. The saw moves, not the piece you're cutting. On a 16-foot section of casing, that helps ensure you're always looking in the right direction and shortens setup time at each corner.

Corded vs Cordless Miter Saws

Corded miter saws run on 15-amp motors and do not need a break to swap batteries. The corded model is still the best saw for the money if you're cutting all day in a shop or on a site where there's a regular power supply. A 15-amp 12" double bevel tooth grinder is generally cheaper than a similar cordless tooth grinding kit with batteries.

If power is unreliable or the job moves from room to room, a cordless miter saw is a better option. Brushless 18V and 20V models with 7-1/4" blades crosscut a 2x8 and can be carried to the upstairs with one hand. Higher-voltage 36V, 40V, and 60V platforms now drive 10 and 12-inch blades through framing lumber. Already own batteries? Buy the bare tool, and you'll save a couple hundred dollars.

Choosing Blade Size, Cut Capacity, and Bevel Range

The diameter of the blades determines the depth and width of the cuts. In the 60- to 80-tooth trim pattern, a 10-inch blade spins faster, flexes less, and is cheaper to replace. A 12” blade will cut larger and taller pieces of stock, such as tall baseboard that is standing straight against the fence. The 24- to 40-tooth blade frames faster and cooler.

Check these specs before you buy:

• Crosscut width at 90 and 45-degree angles

• Vertical capacity for baseboard and nested crown

• Bevel range - most double bevel saws are beveled 45 degrees either side; some are a few degrees beyond

• If you have to transport the saw between projects, you will need to consider weight

• Dust port size and whether it fits your shop vac hose.

Frequently Asked Questions

Should I buy a 10-inch or 12-inch miter saw?

If you primarily cut trim, choose a 10" saw - perfect for lighter weight and lower-cost blades. If you regularly use framing lumber, wide shelving, or tall baseboard, go for 12 inches.

Do I need a sliding mitre saw or will a compound saw do?

A fixed compound saw has a 6” width or less that covers your boards. Use a slider for stair treads, shelving, 2x10s, or 2x12s.

What is the difference between single bevel and double bevel?

A single bevel saw tilts one direction, and for the opposite cut you turn the board over. A double bevel saw tilts both ways, thus saving time in crown and long trim.

Will a cordless miter saw work for daily trimming?

Yes. Pine, MDF, and poplar trim are light work for a brushless motor. Store a second battery on the charger, and you'll never have to wait to see if it is fully charged.

Is it possible to cut metal or aluminum with a mitre saw?

Aluminum: yes (carbide blade for non-ferrous metal, workpiece clamped down, manufacturer's approval). Steel: no. Always use a metal-cutting chop saw or cold saw and NEVER use an abrasive wheel on a miter saw.
