The Nikken Reamer Series is engineered for exceptional precision in hole finishing operations. Built from high-performance materials like ultra-fine carbide or hardened HSS, these reamers achieve micron-level tolerances and fine surface finishes. Ideal for use in CNC machining centers or manual setups, they are available in multiple geometries—short, long, straight flute, or spiral flute—to suit various applications. Nikken reamers support operations in steel, cast iron, aluminum, and other materials, with options for coatings such as TiN or TiAlN to enhance wear resistance. Manufactured in Japan under stringent quality control, they are trusted for consistent, high-accuracy results in critical machining industries.
