A table saw sled is a carriage that rides in the saw's miter slots and carries the board across the blade for crosscuts. You need one only if you make a lot of crosscuts, and it has to fit your saw's miter slots and follow the manual's setup.

This guide explains what a sled does, how it differs from a miter gauge and what to check before you buy. It also compares three sled kits, so you can see the range.

What a table saw sled does

A sled sits on the saw's table and runs in the miter slots on each side of the blade. The board rests on the sled, which moves it across the blade in a straight line.

Most sleds have a fence that holds the board square to the blade, and some add a stop block for repeat lengths. The fence and the stop change the cut, so set them with care.

How a sled differs from a miter gauge

A miter gauge is a guide that slides in one miter slot and holds the board against it. The gauge is simple, and it works for many crosscuts.

A sled carries the whole board on a larger surface, which helps when the stock is wide or when you need the same length more than once. Our how to use a table saw walkthrough covers the miter gauge in the basic setup.

Do you need a table saw sled?

You need a sled if you make many crosscuts, or repeat cuts of the same length. A beginner who crosscuts rarely can learn the miter gauge first and add a sled later.

A sled also suits boards that are too wide or too awkward to hold against a gauge. If your work is mostly rips along the grain, a sled isn't the tool you need.

Check the miter slots before you buy

Most table saws use a 3/4-inch by 3/8-inch miter slot. Measure your saw's slot before you buy bars or a kit, since the bars and runners have to fit it.

The manual shows the slot size and where the blade sits relative to the slot. The sled's instructions show how to set the fence square to the blade, and you should follow both.

Table saw sled and the miter slot

A sled rides in the slot, so the slot's size decides which bars and runners fit. Measure the slot's width and depth, then compare them with the bars you plan to buy.

Sled kits and what they include

A kit is a set of parts you assemble into a sled. It includes the runners or track and the hardware, and you supply the base and the fence.

The three kits below show the range, from a basic set of runners to a fuller kit with a blade guard.

Miter bars for a sled you build yourself

Miter bars are the runners that ride in the miter slots, and the base is made from wood or another flat material. Choosing bars is the first step in a DIY sled.

Check the bars' length and thickness against the slot and your base before you assemble it. Predrilled holes make the assembly easier, but the finished sled still needs its fence square to the blade.

A sled kit with a blade guard and stop

A fuller kit adds a T-track, a flip stop and a blade guard. The T-track lets you mount a stop, which helps with repeat lengths when the stock sits square.

The blade guard that comes with the kit covers the blade on the sled. Check how it fits your saw, and keep the saw's own guard and riving knife set up as the manual says, since the sled's guard doesn't replace them.

Keep your hands clear of the blade

Keep your hands on the sled handle or the stock, and out of the blade path. Never reach across the blade, even when the sled is on the table.

Never cut freehand, and don't remove a guard or a riving knife to make a sled fit. If a part gets in the way, check the manual before you change the setup.

Sled or miter gauge: which should a beginner use?

A beginner should learn the miter gauge and the manual's crosscut steps first. That's the setup most manuals describe, so it gives you a reference for the saw.

Add a sled once you make crosscuts often, or when you need repeat lengths. Our table saw kickback guide explains the setup points that apply to any crosscut.

Push tools still matter with a sled

A sled doesn't replace push tools for the parts of a cut that the sled doesn't cover. The manual says when a push tool should be used, and our table saw push stick roundup compares the shapes.

If you add a sled to your shop, keep the push tools near the saw. Store them where you can reach them without moving your hands near the blade.

Dado sets and sleds are different jobs

A dado set cuts a wide groove, and a sled carries a board across the blade. They're separate jobs, and the setup for each one differs.

Our table saw dado blade guide explains what a dado set does and what the manual needs to allow. For the saw itself, see our portable table saw guide.

Which sled setup should you choose?

If you crosscut often, a ready-made kit or a fuller kit with a stop suits you best. If you want to build your own, start with the miter bars and a base you can square.

Whichever table saw sled you choose, measure your saw's miter slot first, and read the manual before you change the fence or the blade. Wear eye and ear protection, and keep your hands clear of the blade path.

Frequently asked questions

What is a table saw sled?

A table saw sled is a carriage that rides in the saw's miter slots and carries the board across the blade. It's used for crosscuts, and it holds the board against a fence so the stock rides on the sled instead of sliding along the saw top.

Do I need a sled for a table saw?

You need one if you make many crosscuts or repeat lengths, while a miter gauge may be enough if you cut across the grain rarely. Decide by the work you do most.

What size miter slot does a sled need?

Most table saws use a 3/4-inch by 3/8-inch miter slot, so measure your saw's slot before you buy. The Catcan kit says it fits most standard table saw slots, and the POWERTEC kit uses a 24-inch T-track to mount its stop.

Is a sled kit easier than a ready-made sled?

A kit takes time to assemble, and the result depends on how carefully you build it. A ready-made sled is set up for you, but it still needs checking against your saw and the manual.
