A product is only as good as the tools that made it. Their quality is reflected not only in the finished product, however, but also in the production costs: The longer the tools last, the cheaper production – and thus ultimately the product itself – is. That is why GCT GmbH in Weingarten, Germany, specializes in the diamond coating of tools, in particular for the electronics industry. Once mocked for its ideas, today the company is the largest manufacturer of diamond-coated tools in the world.
