This is a 2-1/2-inch aggressive plunge cutting saw blade for the Multimaster. This blade has a Japanese pull saw tooth pattern that allows for very aggressive cutting in wood and other materials. Use this blade in place of a handsaw or jamb saw when there's not a lot of room to maneuver. This blade is perfect for doorjambs, baseboards, toe kicks and flooring work. Avoid materials that might contain nails.
