KORLOY

What KORLOY does

KORLOY Inc. is a South Korea-headquartered, privately held industrial manufacturer founded in 1966 (originally as Hangook Metallurgy Inc., rebranded to KORLOY Inc. in 1987) that designs and produces cemented carbide cutting tools for metalworking applications. Its product portfolio spans cutting tool grades (substrate and coating materials), turning tools in ISO and FGT formats, multi-function tools for grooving, part-off, facing and forming, threading tools, milling tools, endmills, and drills. The company's core technology is in-house PVD coating for high-temperature, high-hardness and oxidation-resistant grades and CVD coating for high-temperature and wear-resistant grades, supplemented by the patented AK Chip Breaker geometry (US patent granted 2001). Two Korean production sites (Cheongju and Jincheon factories) handle domestic manufacturing, with additional wholly-owned factories in Qingdao, China (established 2012) and India (KORLOY INDIA MANUFACTURING, established 2018).

KORLOY's business model is direct hardware sales of cutting tools to industrial manufacturing customers, supported by 10 domestic Korean sales offices (Seoul HQ, Kyungin, Joongbu, Honam, Daegu, Ulsan, plus Seoul/Gwangmyeong offices) and 14 wholly-owned international subsidiaries across Germany, USA, China, India, Brazil, Vietnam, Russia, Turkey, Chile, Mexico, UK, and Hungary. Pricing is quote-based and not publicly disclosed. Vertical focus is split between aerospace (AS9100D certified) as a primary segment and automotive, general machinery, and dies/molds as secondary segments. Marketing relies on a digital catalog platform (catalog.korloy.com), trade exhibitions such as SIMTOS, technical publications, downloadable brochures and catalogs, and social media (Facebook, Kakao, Instagram, YouTube). Complementary digital services include the KOMS online management system, KTS technical system, and a genuine product certification portal.

KORLOY operates as an independent corporation with no parent company or external private equity or venture capital backing identified in available sources. It is led by Chairperson Hye-Sub Yun and CEO Jung-Hyun Yim (appointed April 2019). Cumulative Export Tower awards from the Korean government indicate export revenue ramping from USD 5M (1998) to USD 100M (2017), and recent geographic build-out (UK in 2025, Central Europe/Hungary in 2026) confirms ongoing international expansion. Certifications include ISO 9001 (1997), ISO 14001 (2009), AS9100D, and ISO 45001 (2023), and the company holds government designations including World Champ Manufacturer (2021), Material·Components·Equipment Technology Specialized Company (2023), and Rising Leaders 300 enterprise (2024).
