PROBLEM TO BE SOLVED: To develop a single-crystal diamond endmill and provide a cutting tool and machining technique which permit grooves of a minute diameter to process on a hard and brittle material such as quartz glass, silicon, ceramic, etc., or difficult-cutting material such as special metal, composite material, etc., with a high-efficiency, high-quality and a long service life provided. SOLUTION: A cutting edge having superior wear-resistance is formed and a machining method providing good machinability for grinding is obtained, by performing grinding work with the crystal orientation being specified in the tool design stage, paying attention to the physical/chemical anisotropicity of single/crystal diamond. That is, the longest service life for diamond tools is realized by constituting the cutting edge in a crystal orientation which is the most difficult to be processed.
