オーエスジーダイヤモンドツール Company Profile

Maximizing the hardness of diamond, the hardest mineral on Earth, as a weapon.

Since our establishment in 1968, we have been developing, manufacturing, and selling diamond cutting tools. In 2024, we succeeded the business of Micro Diamond Co., Ltd., based in Yokohama, and in December of the same year, we changed our name to "OSG Diamond Tool Co., Ltd." Our products are utilized in a wide range of fields, including the automotive and electronics industries, as well as in LCD-related, telecommunications, optical components, and medical-related sectors. We will further enhance our capabilities in terms of cost, delivery time, and quality, while actively advancing the development of new proprietary technologies to quickly meet our customers' needs with our products. Additionally, we will explore the world of fine and ultra-precision machining tools. We have standardized the inventory of "N-BRAND" single crystal diamond tools.
