This is a 1-3/8" plunge cutting saw blade for the Multimaster. This blade has smaller teeth to provide for better control and longer blade life. The smaller tooth pattern allows the blade to hit a brad nail in flooring without destroying the blade. 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 material that might contain nails.
