EHWA Diamond

What EHWA Diamond does

EHWA Diamond is a privately-held Korean industrial diamond tool manufacturer founded in 1975 and headquartered in Osan-si, Gyeonggi-do, with operations in 15+ countries. The company operates through three business units: Electronics (semiconductor IC, display, LED, and solar cell manufacturing tools including CMP pad conditioners, back-grinding wheels, dicing blades, scribing wheels, and diamond wires), Precision Machining (vitrified CBN wheels, rotary dressers, PCD/PCBN cutting inserts, and stationary dressers serving automotive engine/gear, bearing, aerospace, glass/optical, and medical applications), and Construction/Stone (saw blades, drill bits, wire saws, and mining core bits featuring the proprietary ZENESIS patterned diamond technology platform).

The company's core technology rests on its ZENESIS patterned diamond platform, which enables custom design and mass production of application-optimized diamond patterns, and patented CVD CMP pad conditioner tip configurations that maintain a consistent apex profile across the conditioning cycle. Advanced materials such as Polycrystalline Diamond (PCD), Polycrystalline Cubic Boron Nitride (PCBN), Chemical Vapor Deposition (CVD) diamond, and a hybrid HBN material round out the technical stack.

EHWA generates revenue through B2B hardware sales of custom and catalog diamond tooling, with quote-based pricing for application-specific solutions. The go-to-market is sales-led, executed via wholly-owned sales subsidiaries in Korea, the US, Japan, Germany, Italy, India, Mexico, and Thailand, supported by regional manufacturing plants in China, Vietnam, Indonesia, and Korea. Disclosed sales were 375 billion KRW in 2024 (peak) and 361 billion KRW in 2025, with the company's stated vision to be a global leader in diamond tool manufacturing.
