SawStop saws offer a safety feature unique in the industry: a braking system that can reduce a potentially severe injury to just a minor cut. Within 5 milliseconds of detecting contact between your skin and the saw blade, the braking system automatically stops the blade, retracts it under the saw’s table and shuts off power to the saw’s motor. This all happens quicker than the eye can see and certainly faster than anyone can react. If the system ever activates, the blade and the brake cartridge are easy to replace, returning the saw to normal operation in just a few minutes.
