Frequently Asked Questions

What kind of 10" blades can I use for the cast iron saws?

Any 10” standard-tooth steel blade with steel or carbide teeth can be used. Do not use blades with tooth “shoulders” (often called depth-limiting or anti-kickback shoulders), as these blades will take longer to stop in the event of an accident. Do not use blades with non-conductive hubs or teeth, as the safety system will not allow the saw to operate with these blades installed.

Can I use an 8" Dado stack?

Any 8” standard-tooth steel stacked dado set (max width: 29/32”) with steel or carbide teeth can be used. A zero-clearance insert for your dado set must be purchased along with the required Dado Cartridge. Do not use dado sets with solid-plate interior chippers, blades with molding heads, or “wobble” dado sets as the brake cartridge is not designed to stop those blade types. Also do not use blades with tooth “shoulders” (often called depth-limiting or anti-kickback shoulders), as these blades will take longer to stop in the event of an accident. Additionally, we recommend only using dado sets wherein the interior chippers have between two and four teeth per chipper to limit the impact on the saw during an activation. SawStop manufacturers an 8” Premium Dado Set (BTS-DS8-2402) that can be used on all SawStop saws except the Compact Table Saw.

Can I use thin and thick kerf 10" blades with a SawStop saw?

The SawStop safety system is designed for use with standard 10” blades with kerfs from 3/32” to 3/16”. Blades with kerfs much thinner than 3/32” should not be used because those blades might not be strong enough to withstand the force applied by the brake when it activates. As a result, those blades might deform and stop more slowly in the event of an accident, resulting in a more serious injury. Blades with kerfs much thicker than 3/16” are heavier than standard 1/8” kerf blades. Therefore, those blades should not be used because they may stop more slowly than standard blades in the event of an accident, resulting in a more serious injury. Similarly, stacks of 2 or more 10” blades should never be used on your SawStop saw as the combined weight of the blades may be too heavy to stop quickly. If you need to use a blade with a kerf thicker than 3/16”, use an 8” dado set with the optional SawStop 8” dado cartridge. The dado cartridge is designed for use with 8” dado sets up to 29/32” wide.

Do any of your saws have scoring blades?

We do not have a scoring blade on any of our saws. Scoring blades cannot be used with our saws due to the stopping technology.

Can I use a sanding disc on your saws?

We do not recommend installing any kind of sanding disc or cutoff disc on a SawStop table saw.

What if my blades are not precisely 10” (or 8” dado stack)?

The vast majority of commercially-available blades are accurate to their advertised diameter, and work well in SawStop saws. If your blade is larger or smaller than the advertised size, SawStop cast-iron saws allow for some adjustability of the blade/brake gap to accommodate. Jobsite Saw blade/brake gap is not adjustable, so users should not operate blades more than 1/16th inch diameter over the specified blade size. Never use a blade that does not “clear” the aluminum brake pawl.

What about coated blades or coated teeth?

Steel blades and dado sets with a lacquer finish or other coating on the teeth should not be used as the coating may inhibit or slow the speed at which the safety system detects skin contact. However, most coated blades do not cover the blade teeth. Those blades may be used on SawStop saws.

Do you sell direct?

We sell only through authorized SawStop dealers. You can find a list of dealers on our site at Please include your zip code in the “where are you?” field and be sure to select the correct model you are interested in viewing. We also have a great build and price feature on our site that walks you through any saw configuration with accessory options,

How can I be certain the safety system is working?

The SawStop safety system continuously performs many self-checks to ensure the components of the safety system are working properly. The safety system will not allow the motor to start (or to remain running) unless every component of the safety system is working properly.

Can I get a serious injury using a SawStop saw?

In the vast majority of cases, coming in contact with the spinning blade will result in a minor cut. However, if your hand moves into the blade at very high speed, it is possible for you to receive a serious injury.

What happens if the blade comes in contact with a nail or staple in the wood?

Generally, the safety system will not activate when a nail or staple is cut. Although conductive, these objects are not large enough to cause the safety system to activate unless they are grounded to the table or operator when they contact the blade.

Can I use Gloves while operating a SawStop?

The SawStop safety system will protect you even if you are wearing gloves. In that case, the system will trigger when the blade cuts through the glove and touches your skin. It is possible that the blade could snag on the glove and pull your hand into the blade, resulting in a slightly deeper cut. That is why SawStop recommends not wearing gloves when using a SawStop saw. However, if you decide to wear gloves, you are still protected.

What is the activation cost?

If you activate the safety system’s brake, you will need to replace the brake cartridge and evaluate the condition of the blade for future use. Replacing the brake cartridge is simple and can take as little as 90 seconds to complete. A standard brake cartridge costs $95 USD and a dado brake cartridge $115 USD. SawStop saws are designed to absorb the force of activation and are not damaged by it.

Can you reuse the blade after activation?

When the safety system activates, it will sometimes damage one to more teeth on the blade. Some users discard and replace the blade, while others choose to have their blades inspected/repaired by a qualified specialist.

Am I protected during coast down?

Yes, if you are using the red paddle to turn the blade on/off, the brake is still actively monitoring the coast down rotation. The yellow power switch is what powers the cartridge to begin monitoring the blade, so as long as that remains on, the cartridge will activate during coast down.

What is Bypass Mode?

Bypass Mode deactivates the safety system’s braking feature, allowing you to cut aluminum, very wet/green wood and other known conductive materials. If you are unsure if material you need to cut is conductive, you can make test cuts using Bypass Mode to determine if it will activate the safety system’s brake.

Will moisture activate the brake?

SawStop saws cut most wet wood without a problem. However, if the wood is very green or wet (for example, wet enough to spray a mist when cutting), or if the wood is both wet and pressure treated, then the wood may be sufficiently conductive to activate the brake. If you are unsure if the material you need to cut is conductive, you can make test cuts using Bypass Mode to determine if it will activate the safety system’s brake. The red light on the control box will flash to indicate conductivity.

Does cold affect SawStop saws?

Cold ambient temperatures should not affect your saw mechanics. However, your saw’s brake cartridge contains “computer-like” parts that can be affected by extreme cold. If the cartridge is stored in temperatures well below freezing, the saw won’t turn on until the cartridge warms up. If you are in an extremely cold climate, we recommend removing the cartridge (which you can do with the blade in place) and storing it above freezing. Alternatively, some customers choose to leave the yellow “hard” power switch on all the time. This provides just enough heat to the cartridge to help ensure startup in spite of extreme ambient cold.

Do the saws come equipped with a magnetic switch?

Our saws have a magnetic switch that prevents it from coming back on.

What kind of dust collection system do I need for your Cast Iron saws?

We recommend a minimum of 350 CFM (PCS/CNS) or 400 CFM (ICS) to the 4” port. Even the largest wet/dry vacuums or portable dust extractors will not supply the CFM needed for proper dust extraction from our cast iron table saws, so we recommend one of the many types of stationary solutions. To get a better understanding of comparing wet/dry vacuums to a stationary collector, visit

Does my aftermarket accessory/saw work with SawStop saws/products?

There are many different saws and other product choices on the market, each with its own installation and/or modification requirements. SawStop doesn’t test on the many other-brand aftermarket items, and therefore don’t have the necessary information to recommend your best result. The manufacturer of the product you are interested in is likely the best place to start, as they may have a better idea of necessary modifications, if any are needed.

How does dust collection compare on the JSS vs CNS?

The Jobsite Saw features an enclosed dust shroud. Gates swing open to allow full access to the blade and cartridge, and magnet latches secure the doors in place for operation, delivering superior collection inspired by SawStop’s cabinet saws. The Contractor Saw is a partially enclosed design. As such, while the dust collection is good, it will not collect as efficiently as the Jobsite Saw.
