For deck boards, a round-over router bit is commonly used to smooth and slightly round the edges, helping to prevent splinters and create a finished look. A 1/4-inch or 3/8-inch round-over bit is typical for this purpose. Always use a carbide-tipped bit for durability, especially on hardwoods or pressure-treated lumber.
