Abstract
A coated tool in a non-limiting embodiment of the present disclosure includes a base composed of WC-based cemented carbide including a WC particle and a binding phase, and a diamond film located on the base. In a cross section orthogonal to a surface of the coated tool, the base has a lower content of the binding phase in a surface of the base than a midportion of the base. In an interface region between the base and the diamond film, a WC particle located away from the base is an isolated WC particle, and the number of the isolated WC particle present per interface length of 10 μm is 4 or less. A cutting tool in a non-limiting embodiment of the present disclosure includes the above coated tool.
