A table saw does one thing that no other portable tool replicates well: it rips boards to a consistent width along their entire length. You can crosscut on it, dado with it, and make all kinds of joinery, but the rip cut is why it exists. The question isn't whether you need one (if you're building cabinets, furniture, or anything with plywood, you do), it's which type fits your space, your work, and your budget. Jobsite saws fold up and fit in a truck. Contractor saws have cast iron and heavy fences. Cabinet saws weigh 400+ lbs and don't move. Here's how to pick.
Jobsite Table Saws
Jobsite saws are portable. They weigh 45 to 65 lbs, have folding stands with wheels, and run on standard 15-amp household circuits. Rip capacity ranges from 24-1/2 to 32-1/2 inches depending on the fence system. DeWalt's DWE7491RS (32-1/2-inch rip, rack-and-pinion fence) and Ridgid's R4514 (25-1/2-inch rip, lifetime warranty) are the two models that show up on every comparison list. Milwaukee's 2736-21HD runs on M18 batteries, which is a real advantage on sites without power.
The limitations are real. Lighter tables vibrate more, which shows up in cut quality on long rips. Fences on jobsite saws aren't as flat or rigid as contractor or cabinet saw fences. Dust collection is poor. The small table surface makes handling sheet goods awkward. But for most home shops and job-site work, a good jobsite saw handles 90% of what you'll throw at it.
Contractor Table Saws
Contractor saws bridge the gap. They have cast-iron or granite-composite tables, better fences, and more mass (200 to 300 lbs). They're semi-portable, meaning you can move them with help, but they're really meant to sit in one spot. The motor hangs off the back on a pivot, which saves space compared to a cabinet saw but limits dust collection. Most run on 15-amp 120V circuits, though some can be wired for 240V.
Rip capacity is typically 30 to 36 inches. The heavier table absorbs vibration, so cuts are smoother. A T-square fence system (Biesemeyer-style) locks parallel to the blade consistently. For a one-car garage shop where the saw needs to fit against a wall when not in use, a contractor saw is the sweet spot. SawStop's Contractor model adds flesh-detection safety. Grizzly and Jet make solid options in the $700 to $1,200 range.
Cabinet Table Saws
Cabinet saws are the professional standard. The motor is enclosed inside the cabinet (hence the name), which makes dust collection significantly better because the cabinet contains most of the sawdust and routes it to a 4-inch port. Tables are cast iron, 400 to 600+ lbs total. They run on 240V circuits with 3 to 5 HP motors. Rip capacity is 30 to 52 inches.
The price reflects the build quality: $1,500 to $4,000 for a standard cabinet saw, $3,000+ for SawStop's flesh-detection models. These aren't home-shop tools for most people. If you're building cabinets professionally or running a woodworking business, the cut quality, dust collection, and rigidity justify the investment. For everyone else, a good contractor or jobsite saw does fine.
Rip Capacity and Fence Quality
Rip capacity is the distance from the blade to the fence at its maximum setting. For ripping plywood, you need at least 24-1/2 inches (half of a 48-inch sheet). For ripping wide panels or using crosscut sleds, 30+ inches gives you more working room. The fence is the most important component after the blade. A good fence locks parallel to the blade every time. A bad fence needs constant shimming and checking with a square.
T-square fences (where the fence locks at the front rail only and stays parallel by rigidity) are standard on mid-range and above. Two-rail fences (lock at front and back) are common on jobsite saws. Some jobsite fences feel loose and need manual checking. If a saw's fence frustrates you, aftermarket T-square fence kits exist, but they cost $200 to $400 and the mounting isn't always straightforward.
Safety Features
A riving knife is a curved metal plate that sits behind the blade, inside the kerf. It moves with the blade during bevel cuts and prevents the wood from closing on the back of the blade, which is the primary cause of kickback. Every saw sold today includes a riving knife. Use it. A splitter is a fixed version that doesn't move with the blade. An anti-kickback pawl is a spring-loaded finger that digs into the wood if it starts moving backward. Blade guards sit over the blade and deflect chips. They all reduce risk and none of them slow your work down enough to matter.
SawStop's flesh-detection system is in its own category. The blade carries a small electrical signal. Skin contact changes the signal. The system fires an aluminum brake into the spinning blade, stopping it in under 5 milliseconds. The blade is ruined and the brake cartridge needs replacement ($70 to $100), but your fingers stay attached. It's the only consumer table saw safety system with independent verification of its claims.
Frequently Asked Questions
What size table saw blade do I need?
10-inch is the standard for almost all table saws. It cuts up to 3-1/2 inches deep at 90 degrees, enough for anything up to 4x material. 8-inch blades exist for some compact models. Dado blade sets are also 8 or 10 inches. Get a good 40-tooth combination blade ($25 to $50) for general ripping and crosscutting, and a 60 to 80-tooth blade for plywood and finish cuts.
Can I use a table saw in my garage?
Yes, with caveats. You need 8 feet of clear space in front and behind the blade for ripping long boards, and 4 feet on each side for sheet goods. A jobsite saw on a folding stand can be pushed against the wall when not in use. Dust collection matters more in an enclosed space. At minimum, hook up a shop vac to the dust port. A small dust collector is better.
Do I need a 240V outlet for a table saw?
Jobsite saws and most contractor saws run on standard 120V 15-amp circuits. Cabinet saws need 240V. Some contractor saws can be wired for either. Running a 15-amp saw on a shared circuit with other loads will trip the breaker during heavy cuts. Give the saw its own dedicated circuit if possible.
Is a SawStop worth the price premium?
SawStop saws cost $400 to $1,000 more than comparable saws without flesh detection. If you value keeping all your fingers (and you should), it's hard to argue against the price. The saw itself is also well-built, competitive with Jet, Grizzly, and Powermatic at the same tier. The safety system is a bonus on an already good saw, not a gimmick on a cheap one.
