WebA thin kerf saw blade is a saw blade with carbide teeth that are 3/32 inches wide. This thinness allows for less wasted wood and less sawdust. Thin kerf blades are best used with thin-strip ripping projects and will rip your wood to the exact width needed. It will also put less strain on your motor since there is less material being removed.
