Company information
In 1898, the founder Gottlieb Gühring began the production of cutting tools in Germany based on the belief that "the highest quality conquers the world." In the early days, the number of products was small, and the catalog consisted of only a few pages, but now we have a standard product lineup that exceeds 4,500 types and 100,000 items. "We will not allow others to catch up with us in terms of product quantity and precision" – this belief will continue to be the foundation of our company as we strive to improve. "From standard products to special items, from spindles to cutting edges" – we sincerely wish to be a strong partner for our customers by not only developing and manufacturing cutting tools but also earnestly addressing any challenges related to cutting technology.
