About Quality Tool

Quality Tool is a privately owned US company and a division of Demmer Affiliates of Lansing, Michigan. We opened our doors in 1959 as a Tool & Die manufacturer, and have since grown into the diverse metalworking and assembly business that we are today. Over those 60 years, we have retained the skilled craftsman culture of the original business, that along with a focus on continuous improvement and new technology, we apply every day to every part.
