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 13/16” wide.
