These products serve highly specialized markets requiring ultra-precision machining, particularly in electronics manufacturing, automated machinery, and semiconductor equipment. Union Tool’s cutting tools are primarily made of cemented carbide with advanced coatings and designs tailored for micro-hole drilling, multilayer PCB processing, and materials that demand high durability and precision. Founded in 1938 and headquartered in Tokyo, Japan, Union Tool operates extensively in Japan, China, Taiwan, and internationally, with significant strength in supplying components for electronic manufacturing and industrial automation sectors. The company develops proprietary manufacturing equipment to maintain high standards of quality and dimensional accuracy, including specialized grinding machines, image processing inspection devices, and automated packaging systems. Union Tool also manufactures high-performance linear guides critical for precision equipment, which feature nearly mirror-like sliding surfaces for optimal durability and smooth operation. Recent major developments within the last two years include the announcement of a new factory construction project to enhance PCB drill production capabilities, reflecting a strategic expansion to meet increasing demand. The company also released new carbide end mill products with advanced coatings such as DLC and CBN varieties, aiming to improve tool life and performance. Union Tool opened a new sales office in Fukuoka in early 2025 to strengthen its regional sales and customer support network. Additionally, the company was awarded the Technical Achievement Award from the Japan Cutting & Wear-resistant Tool Association in 2024, recognizing its leading-edge technology advancements.
