Demmer Affiliates of Lansing, Michigan is the parent company of Quality Tool, a privately held US business. We started out as a tool and die manufacturer in 1959 and have since expanded to become the varied metalworking and assembly company that we are today. Over the course of those 60 years, we have maintained the original company's skilled craftsman culture, which we apply to every item on a daily basis coupled with an emphasis on new technologies and constant progress.
