For most standard through rip cuts, set the table saw blade about 1/8 to 1/4 inch above the top of the workpiece. That is the practical range specified in SawStop table-saw instructions and echoed in machine-guarding training material. It leaves enough tooth exposure to cut through the stock while avoiding needless blade exposure above it. SawStop Jobsite Saw Pro manual and SawStop Compact Table Saw manual

The important distinction is that this is a starting rule for a normal through cut, not a substitute for your saw’s manual or a complete rip-cut setup. Set the blade relative to the actual thickness of the board, then use the rip fence, blade guard, and the correct push device for the cut. Do not try to compensate for an unsafe workpiece or an awkward narrow cut merely by changing blade height.

The practical blade-height rule

With the saw stopped, place the stock beside the blade and raise the blade until the top of its highest tooth is about 1/8 to 1/4 inch above the board’s top face. Follow the lockout and adjustment procedure in your saw’s current manual before making blade-height changes.

For example, using that range:

  • 1/4-inch stock: set the blade roughly 3/8 to 1/2 inch above the table.
  • 3/4-inch stock: set it roughly 7/8 to 1 inch above the table.
  • 1 1/2-inch stock: set it roughly 1 5/8 to 1 3/4 inches above the table.

The measurement is blade exposure above the workpiece, not the total height above the saw table. A blade set for 3/4-inch plywood, for example, should not remain at that height when you switch to 1/4-inch stock.

Why not raise it much higher?

A blade far above the workpiece creates more exposed teeth than the cut requires. It also makes it easier for a hand, push device, offcut, or loose material to contact the blade above the board. Keeping exposure modest is a straightforward way to reduce that unnecessary hazard.

At the other extreme, do not set the blade so low that it fails to complete the through cut. If the board is not fully separated, stop and correct the setup rather than forcing it through the blade.

Use the rule for ordinary through rips

A through rip cuts fully through the workpiece along its length or grain direction. For this operation, SawStop’s instructions call for a blade height approximately 1/8 to 1/4 inch above the workpiece and specify use of the rip fence to guide the stock. SawStop Jobsite Saw Pro manual

Keep the board flat on the table and flush to the fence as it moves through the cut. A rip should not be performed freehand. SawStop’s cabinet-saw manual warns that a rip fence must always be used for rip cuts and that freehand ripping can cause serious injury. SawStop Professional Cabinet Saw manual

Do not use the miter gauge for a rip cut

The miter gauge is for supporting a workpiece in crosscuts, not for guiding a normal rip cut. The Compact Table Saw manual specifically says not to use the miter gauge when making rip cuts; use the fence for the rip instead. SawStop Compact Table Saw manual

Blade height is only one part of a safe rip-cut setup

Before starting a routine through rip, confirm the whole setup—not just the blade elevation.

Use the guard and riving knife when the cut allows it

For through cuts, use the blade guard when your saw’s instructions permit it. SawStop states that the blade guard should be used for all through cuts. SawStop Compact Table Saw manual

Make sure the riving knife, guard, throat plate, blade, and fence are installed and adjusted as your specific saw manual requires. These components and their adjustment ranges differ among saw models. If a guard or riving knife will not fit the intended operation, do not casually remove it and proceed; check the manual’s approved procedure and determine whether the cut is appropriate for the saw and setup.

Lock the fence and keep the stock supported

Set the fence to the finished rip width and lock it before starting the saw. Keep the board flat on the table and against the fence throughout the cut. If the workpiece rocks, is badly warped, cannot be kept against the fence, or lacks adequate support before and after the blade, pause and choose a safer, supported method rather than forcing the rip.

For long boards or sheet goods, make sure you can support the workpiece without reaching over or around the blade. The work must remain controlled from the beginning of the cut until it has passed the blade.

Plan hand clearance before turning on the saw

Do not wait until your hand is close to the blade to decide how to finish the cut. SawStop instructs operators to keep hands at least 6 inches from the blade and to use a push stick when a hand would come within that distance. SawStop Professional Cabinet Saw manual

For the Compact Table Saw, SawStop further specifies a push stick when the distance between the fence and blade is under 6 inches and a push block when it is under 2 inches. Your saw may specify different accessories or limits, so use its current manual as the controlling instruction. SawStop Compact Table Saw manual

What changes for narrow rips and thin material?

The blade-height rule generally stays the same: aim for roughly 1/8 to 1/4 inch of exposure above the workpiece for an ordinary through cut. What changes is how you guide the stock.

As the space between the fence and blade narrows, ordinary hand placement becomes unsuitable. Use the push stick, push block, low fence position, or other accessory approved for your saw. SawStop’s Compact Table Saw instructions describe using a low fence position for narrow rips while still allowing use of the blade guard. SawStop Compact Table Saw manual

Do not hold a narrow offcut between the blade and fence with your fingers. Plan which piece is guided by the fence, where the push device will bear, and how both pieces will clear the blade before beginning.

What about bevel rip cuts?

For a bevel rip, set the bevel angle first, then set the blade height relative to the workpiece. The same general target—only modest exposure above the stock—remains useful, but the blade’s angled teeth make the exposed area look different from a square cut.

Check your manual for guard, riving-knife, fence, and accessory requirements at the selected bevel angle. Do not assume that a setup that works at 90 degrees remains acceptable when the blade is tilted.

When not to attempt the cut on the table saw

Stop and reassess the operation if any of these conditions apply:

  • You would need to rip freehand because the fence cannot be used.
  • You cannot keep your hands at the required clearance or cannot use an appropriate push device.
  • The board will not stay flat on the table and flush to the fence.
  • The workpiece is too long, heavy, flexible, or awkward to support and control through the entire cut.
  • The intended setup requires defeating a guard or other safety component without an approved manual procedure.
  • You are unsure whether the blade, throat plate, riving knife, guard, or fence configuration is correct for the operation.

In those situations, consult the saw manufacturer’s current instructions and use a cutting method that can properly support and guide the material.

Bottom line

For a typical through rip, set the blade 1/8 to 1/4 inch above the lumber. That is a useful, manufacturer-supported baseline—not a reason to overlook the rest of the setup. Use the rip fence, keep the guard installed for through cuts, maintain hand clearance, and switch to an appropriate push stick or push block for narrow work. If the board or setup cannot be controlled safely, do not make the cut until you have a method that can be.
