日進工具 Company Overview

We are a manufacturer specialized in fine and small-diameter end mills, committed to producing products that are "Made in Japan."

Our company was founded in 1954 as a manufacturer specializing in tools. We excel in the field of micro and precision machining, with our main production items being small-diameter carbide end mills with a blade diameter of 6mm or less, and our product lineup exceeds 8,000 items. We have developed and produced equipment focused on micro and precision machining needs, including a standardized micro end mill and drill series with blade diameters as fine as φ0.01mm, diamond-coated end mills and PCD end mills that enable the machining of hard and brittle materials which was previously impossible, and cBN end mills that achieve stable machining accuracy over long periods in the finishing of hardened steel, thus broadly responding to micro and precision machining needs.
