Diamond tool manufacturer Diamut, which became part of Biesse Group in 2002, has announced that it will open a new tool restoration operation run by highly trained Diamut operators and engineers on the Biesse Group campus in Charlotte.  The company’s customers and distributors who use Intermac and other cutting-edge glass and stone machines will be able to send their worn tooling to the Charlotte facility to have it re-profiled and restored, a process often known as “redressing,” starting in early September.
