The story
Founded by Stef Wertheimer in 1952.1
ISCAR was founded in 1952 by metalworker Stef Wertheimer in Nahariya, Israel. The company began as a family business and developed into a tool manufacturer.
During the 1970s and 1980s, ISCAR expanded its catalog of indexable tooling, including inserts and tools for turning, milling, and grooving, along with additional carbide grades and coatings.
In 1982, the company relocated its operations to Migdal Tefen (Tefen industrial zone) in the Upper Galilee. During the 1980s, under the leadership of Stef’s son, Eitan Wertheimer, ISCAR expanded operations into Europe, Asia, and the Americas.
In the 1990s, ISCAR expanded its international operations and developed modular tooling systems for machining applications. Its products have been adopted by manufacturers in sectors including automotive and aerospace.
In 2006, Berkshire Hathaway acquired an 80% stake in ISCAR (through the International Metalworking Companies (IMC) group).
Berkshire Hathaway acquired the remaining shares in 2013, making ISCAR fully owned by Berkshire Hathaway.
2010s–present, ISCAR manufactures metal-cutting tools for machining operations including turning, milling, holemaking, threading, and parting and grooving.
ISCAR is part of the International Metalworking Companies (IMC) Group—a network of over 150 subsidiaries in more than 60 countries.
