LACH Diamond Inc. is a globally recognized manufacturer of high-performance diamond and CBN tooling solutions, serving the machining industry with precision and reliability. Founded in 1982 by Horst Lach, the company operates as a family-owned business with its U.S. headquarters and production facility in Grand Rapids, Michigan. In partnership with its German counterpart, LACH DIAMANT — established in 1922 — the company manufactures expertly engineered tools in both the United States and Germany, supporting customers across a wide range of industries worldwide.
LACH’s technical development team works closely with clients to refine standard tooling and build specialized solutions for unique production challenges, backed by multiple patents that reflect the company’s reputation for pioneering advancements in diamond and CBN tooling.
Diamond and cubic boron nitride (CBN) tools are used in applications where traditional carbide tooling reaches its limits — offering extended tool life, exceptional precision, and consistent results even when machining extremely hard or abrasive materials such as high-alloy steels, ceramics, and composites like CFRP and GRP. With the ability to process large volumes of workpieces with minimal wear, LACH Diamond tools help manufacturers improve efficiency, reduce downtime, and elevate production performance.
