Kickback is the single most common cause of table saw injuries, responsible for roughly 72% of all table saw accidents where the mechanism was documented, according to a national study from Nationwide Children’s Hospital. It happens when the spinning blade catches a piece of wood and launches it back toward you at startling speed. The good news: kickback is almost entirely preventable with the right setup, technique, and awareness of what causes it in the first place.
What Actually Causes Kickback
Kickback occurs when wood pinches against the back of the blade. The teeth on the rear of the blade rotate upward, so when wood makes contact there, the blade lifts the piece off the table and hurls it toward the operator. Two things typically cause this pinching: the wood closes around the blade during a cut, or the wood rotates slightly and contacts the back teeth.
The force involved depends on how much contact area exists between the blade and the wood and how long that contact lasts. Even a brief pinch can generate enough momentum to send a board flying. This is why prevention focuses on keeping the kerf (the slot the blade cuts) open and keeping the wood moving in a controlled, straight path through the blade.
Use a Riving Knife or Splitter
A riving knife is the single most effective safety device for preventing kickback. It sits directly behind the blade and keeps the two halves of a cut board from closing together and pinching the blade. If your saw came with one, never remove it for standard rip cuts.
A splitter does the same job but with a key difference: a riving knife raises and lowers with the blade, and its top edge sits just below the highest tooth. This means you can leave it installed for most operations, including non-through cuts like dadoes and rabbets. A splitter, by contrast, stays at a fixed height and usually needs to be removed for anything other than full-depth cuts. If your saw only has a splitter, it’s still far better than nothing, but you’ll find yourself removing it more often, which means more cuts without protection.
Align Your Rip Fence Properly
A misaligned fence is a hidden kickback trigger. If the back end of the fence angles inward toward the blade, it gradually pushes the wood into the back teeth as you feed it through. This is the exact pinching scenario that causes violent kickback.
Your fence should be parallel to the blade, or angled very slightly away from it at the back. Experienced woodworkers typically aim for the fence to be within 0.010 inches of perfectly parallel. Some prefer a slight outward taper at the back end of about 0.010 to 0.016 inches (roughly 1/64 of an inch) to give the cut piece a hair of extra room and eliminate any chance of binding. Either approach works. What you absolutely want to avoid is any inward taper toward the blade at the back of the fence.
Never Use the Rip Fence for Crosscuts
One of the most dangerous mistakes is using the rip fence as a stop when crosscutting with a miter gauge. The offcut piece can get trapped between the fence and the blade, and since there’s nothing controlling it, the blade catches it and fires it backward. Crosscuts need a different approach entirely.
A crosscut sled is the safest option. Think of it as a cradle: it lifts the workpiece onto its own platform and holds everything steady through the entire cut, including the offcut. This is especially valuable for small or awkward pieces that would be difficult to control with just a miter gauge. If you do use a miter gauge instead of a sled, keep the workpiece firmly against the gauge and never pull the stock back through the spinning blade when the cut is finished. Any rearward movement near the blade creates a kickback opportunity.
Position Featherboards Correctly
Featherboards apply steady pressure to keep wood tight against the fence or the table surface, which reduces the chance of the wood wandering into the blade at an angle. But their placement matters. On a table saw, always position a featherboard forward of the blade, between you and the front edge of the blade, with the fingers pointing in the feed direction. Placing a featherboard beside or behind the blade pushes the offcut into the back teeth, which is exactly what you’re trying to avoid.
The one exception is non-through cuts like grooves or rabbets, where there’s no offcut being separated. In those cases, you can position the featherboard right at the cutter to hold the board tight for accuracy.
Watch for Internal Wood Stress
Some boards carry internal tension from how the tree grew or how the lumber was dried. When you rip these boards, the two halves want to move, either springing apart or, more dangerously, closing together on the blade. You might notice the kerf narrowing as you feed the board through, sometimes closing to half its original width before the cut is even two-thirds complete. That closing kerf is your riving knife earning its keep.
You can test for internal stress before cutting. Flatten one face of the board, then cut a thin strip and watch whether it curls or bows. If it does, the wood has significant tension. With stressed wood, make sure your riving knife is in place, feed slowly, and be prepared to use a wedge or shim in the kerf behind the riving knife if the wood starts binding heavily. Hardwoods like maple are particularly prone to this.
Stand Out of the Line of Fire
Even with every precaution, your body position is your last line of defense. Stand to the left side of the blade, not directly behind it. Never have any part of your body in line with the blade’s path. If kickback does happen, the wood launches straight back along the line of the cut. Standing offset by even a foot puts you out of the projectile’s trajectory.
This also gives you better control when feeding wood past the blade, since your push hand naturally guides the stock between the blade and fence from a comfortable angle rather than reaching directly over the blade.
Set the Right Blade Height
Raising the blade so the teeth sit about 1/4 to 3/8 of an inch above the top of the workpiece changes the angle at which the teeth contact the wood. With the blade too low, the teeth push more horizontally against the wood rather than cutting downward through it, which increases the grabbing force that leads to kickback. A properly set blade height means the teeth are cutting more efficiently with less opportunity to lift the workpiece.
Feed Stock Steadily and Deliberately
Hesitation mid-cut is a common kickback trigger, especially for newer woodworkers. When you stop feeding the wood but the blade keeps spinning, the wood can drift slightly, or heat can cause the kerf to close. Feed the workpiece at a steady, consistent pace from start to finish. If something feels wrong, like the wood is binding, vibrating, or the motor is bogging down, don’t freeze and don’t try to pull the wood backward. Turn off the saw and wait for the blade to stop completely before investigating.
Use a push stick for narrow rip cuts so your hands stay well away from the blade and you can maintain consistent forward pressure through the entire cut. For pieces narrower than about six inches between the blade and the fence, a push stick isn’t optional. It’s the only way to maintain control through the back half of the cut where kickback risk is highest.
