Circular saw, mitre saw or table saw? What each one does best

All three saws use a round, toothed blade, and all three can cut a board in half. But they're built around different kinds of cut, and choosing the wrong one means fighting the tool on every project. This guide explains what each saw does best, what the sizes and specifications mean, and which one makes sense as a first purchase.

The three kinds of cut

It helps to name the cuts first:

• Crosscut: across the grain, usually to shorten a board.
• Rip cut: along the grain, usually to make a board narrower.
• Mitre: an angled crosscut, as in a picture-frame corner.
• Bevel: the blade tilted, so the cut edge is angled through the thickness.
• Sheet cuts: long straight cuts in plywood, MDF or OSB panels.

Each saw is strong at some of these and awkward at others.

Circular saw: the portable all-rounder

A circular saw is handheld: you bring the saw to the work. The blade projects below a flat base plate (the shoe), and you guide it along a line, a clamped straightedge or a guide rail.

Best at: cutting sheet goods to size, rough crosscuts in framing lumber, rip cuts in long boards, and any job where the material is too big or awkward to carry to a stationary saw.

Sizes. The most common corded size in North America is 7-1/4 in (184 mm), which cuts through standard 2× lumber at 90° and 45° in one pass. Cordless saws are often 6-1/2 in (165 mm), which is lighter but cuts slightly less deeply. Blade size mainly determines maximum depth of cut, so check that figure at 90° and at 45°.

Variations. A standard "sidewinder" has the motor beside the blade. Worm-drive and hypoid saws put the motor behind the blade through a gearbox, giving more torque for heavy framing but more weight. A track saw is a plunge-cutting circular saw that runs on a guide rail, making splinter-free, straight cuts in sheet goods almost as accurate as a table saw.

Limitations: accuracy depends on your setup, and small pieces are hard to cut safely.

Mitre saw: fast, accurate crosscuts and angles

A mitre saw (often called a chop saw) mounts the blade on a pivoting arm above a small table. You hold the board against a fence and pull the blade down through it. The table swivels for mitre angles, and on a compound mitre saw the head also tilts for bevels.

Best at: repeatable, square crosscuts and precise angles, making it the natural tool for trim, skirting boards (baseboards), door casing, crown moulding, decking and framing.

Sizes. Common blade sizes are 8-1/2, 10 and 12 in (roughly 216, 254 and 305 mm). Blade size mostly sets how tall and thick a board you can cut.

Types:

• Single-bevel compound: tilts one way; you flip the workpiece for opposite bevels.
• Dual-bevel compound: tilts both ways, which is handy for crown moulding and long trim.
• Sliding compound: the head slides forward and back on rails, greatly increasing crosscut width. A non-sliding saw might crosscut boards about 5–6 in wide; a sliding 12-inch saw can handle roughly twice that or more. Check the maximum crosscut width at 90° and 45° in the specifications.

Limitations: it can't rip boards lengthwise or cut large sheets.

Table saw: the accurate ripping machine

On a table saw the blade rises through a flat table, and you push the material past it. A rip fence parallel to the blade makes long, straight, repeatable rip cuts, and a mitre gauge or a sled handles crosscuts on smaller pieces.

Best at: ripping boards to precise widths, cutting sheet goods into strips, making repeated parts of identical width, and joinery such as grooves and rebates.

Types:

• Jobsite (portable) saws: light enough to carry, often with a folding stand. Most DIY users start here.
• Contractor and hybrid saws: heavier, with more stable tables and fences.
• Cabinet saws: heavy, powerful, very accurate; usually need a dedicated workshop and sometimes a 240 V circuit.

Sizes. A 10-inch (254 mm) blade is standard for most home saws. Rip capacity, the maximum distance between fence and blade, matters more than blade size if you'll cut sheet goods: a full 4 × 8 ft sheet needs a lot of capacity, or a circular saw to break it down first.

Limitations: it takes up space, and it demands the most respect of the three (see safety, below).

Side by side

Cut or job	Circular saw	Mitre saw	Table saw
Crosscutting boards	Good	Best	Good (with sled or mitre gauge)
Angled trim cuts	Fair	Best	Fair
Ripping boards	Fair (with guide)	Not possible	Best
Full sheets of plywood	Best (with guide or rail)	Not possible	Fair (needs support)
Portability	Best	Good	Fair (jobsite models)
Repeatability	Fair	Best	Best

For curved cuts, none of these is the right tool: see our guide to jigsaws and reciprocating saws.

Blades matter as much as the saw

• Tooth count. Fewer, larger teeth cut fast and rough (good for ripping and framing); more teeth cut slowly and cleanly (good for trim and plywood). A 7-1/4 in framing blade might have about 24 teeth; a 10 in or 12 in fine crosscut blade 60–80.
• Kerf. Thin-kerf blades remove less material and suit lower-powered and cordless saws.
• Match the arbor size and maximum speed printed on the blade to the saw.

A sharp, suitable blade often improves cut quality more than upgrading the saw.

Safety for every saw

• Wear eye and hearing protection, and a dust mask for MDF and long sessions. Connect a vacuum where the saw has a port; see our guide to wet/dry shop vacuums.
• Disconnect power (unplug or remove the battery) before changing blades or adjusting.
• Support the work so the cut doesn't close on the blade. With a circular saw, support both sides and let the offcut fall freely, and never hold the workpiece across your knee.
• Let the blade stop before lifting a mitre saw or reaching near any blade.
• On a table saw, keep the riving knife and guard fitted wherever the cut allows, use push sticks for narrow rips, never cut freehand without the fence or mitre gauge, and don't use the rip fence as a length stop for crosscuts: an offcut trapped between blade and fence can be thrown back at you. Kickback, when the blade catches the workpiece and throws it towards you, is the main hazard, so stand slightly to one side of the blade's path.
• Some table saws include a flesh-sensing system that stops the blade on skin contact. It's a valuable extra layer, not a replacement for safe technique.

The short version

1. One saw for general DIY and building projects? A circular saw, ideally with a guide rail or straightedge.
2. Lots of trim, flooring or decking? Add a mitre saw; choose sliding if you'll cut wide boards.
3. Furniture, cabinets or repeated rip cuts? A table saw, used with its guard, riving knife and push sticks.
4. Buy good blades, match tooth count to the job, and check cutting capacities rather than blade size alone.
