About TouchDRO

TouchDRO is designed and assembled by a family-owned company in Portland, Oregon. In 2012, we set out to create a powerful, customizable DRO that small shops and home machinists could actually afford. TouchDRO started as a way to get more done with our own hobby-grade manual machines. Today, it is trusted by tens of thousands of machinists around the world, from hobbyists to prototyping and production shops.

Whether you're adding scales to a new machine or replacing an aging DRO console, you get a system backed by years of active development and a community of machinists who help each other get the most out of it.
