There are 2 main types of mallets: the rubber mallet and the wooden mallet. Rubber mallets are often used in auto body work, construction, woodworking and do-it-yourself projects. Because they deliver a softer blow than other mallets, they are less likely to leave marks or dent the item you are working with. Rubber mallets are also used in upholstery work to drive nails and metal studs into furniture without damaging the wood. Wooden mallets are typically used in carpentry for driving dowels or fitting 2 pieces of wood together snugly. If a mallet isn't exactly the tool you're looking for, a dead blow hammer looks and performs similarly, because it doesn't damage the surface of items you're working with either.
