On the cutting edge of technology（4-4）

As machine tools became more sophisticated, cutting tools became more complex.

Before World War II, high-speed-steel tooling was used for most metalcutting applications. Although cemented-carbide cutting tips had been around since the 1930s, many machines did not have the rigidity, power, and strength needed to optimize the use of this new tooling. However, with advances in machine-tool technology during the war years, which created more powerful production machines, cemented-carbide cutting tips came into fashion, and indexable inserts became the way to go.

Iscar: A "Swiss-watch" approach to tool manufacturing

Twenty years before Stef Wertheimer founded Iscar Ltd., the philosophical foundations were laid for this manufacturer of precision metalcutting tools. In 1937, when Wertheimer was 10 years old, his father immigrated from a small German village to Palestine. At 14, he opted for an apprenticeship in a Tel Aviv camera repair shop, rather than continue his formal education. Here, he learned the basics of optical engineering. Early in World War II, Wertheimer put this knowledge to work repairing bombsights and air conditioners for the British.

In 1945 he was recruited for the Palmach—the volunteer combat forces of prestatehood Palestine—where he was put in charge of an underground munitions factory.

Wertheimer realized that to make good guns, you had to have precise tools.

From these experiences, he developed an intense commitment to Israeli self-sufficiency with entrepreneurism as its cornerstone.

Wertheimer began Iscar Ltd. 14 years later and never forgot his commitment. The enterprise has grown to a group of precision tool manufacturing firm with annual sales of $320 million.

Iscar Ltd. is one of Israel's leading export companies. Exports account for over 97% of sales through a global network of 25 subsidiaries and 25 agents in six continents.

In 1976, Iscar created the first Grip tool, a unique design for cut-off applications which rapidly became widely accepted. This breakthrough was followed by the introduction of a group of multifunction turning, grooving, facing and threading tools.

In 1982, Iscar moved its Tool Plant to Tefen in Galilee. By 1989 the Carbide Unit and Marketing Center were on-stream in new premises in Tefen.

Beginning in 1990, Iscar focused on the creation of an entirely new line of milling tools. The same inserts could be used on a variety of milling cutter bodies for different applications.
