TouchDRO is a digital readout that runs as an Android app on a tablet, paired with a wireless encoder interface box that connects to the scales, touch probe, and RPM sensor on your machine.
Because TouchDRO runs on a tablet, you get a crisp, easy-to-read display. You can configure the layout for your machine and the way you work. The display shows where the cutter is on the part as you move the handles — and you can drop a drawing on top of it to machine more complex shapes than you'd normally tackle on a manual machine.
Choose scales that fit your machine, or check whether the ones you already own are supported. Most modern and many legacy scales work.
Pick the adapter for your mill or lathe, or build your own from a DIY kit. See the comparison page to decide which one fits.
TouchDRO runs on most Android and Amazon Fire tablets — use one you already own, or pick from our recommended models for your size and budget.
Great for Bridgeport-style and benchtop column mills. A 4-axis readout with quill scale summing for knee mills, touch probe support for finding edges and setting tools, and a spindle tachometer for chip-load and surface speed calculations. Works with the glass, magnetic, and capacitive scales you already have.

Great for mini lathes, small benchtop lathes, and larger gunsmith lathes. A 4-axis readout that handles carriage, cross-slide, and tailstock. Use what fits each axis — a glass or magnetic scale on the carriage, a magnetic scale on the cross-slide, a capacitive scale on the tailstock quill. TouchDRO reads them all into the same display.

This product is a game changer, especially on my mini mill. Forget about manual marking out, simply enter the data into TouchDRO. Fantastic.

Far better than the many cheap Chinese options. This system gives you the flexibility to build your own DRO based on what is important to you.

I would not use my milling machine without this software.

Hooked up my existing magnetic readers and the calibration was within two tenths without any adjustment.

About TouchDRO
In 2012, we set out to create a capable, customizable DRO that small shops and home machinists could afford. TouchDRO started as a way to get more done with our own 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, direct product support, and practical feedback from machinists who use TouchDRO in real shops.
Scale compatibility
The most common new install — affordable, accurate, and durable. TouchDRO works with Ditron, Aikron, Sino, Electronica, and similar TTL/RS-422 quadrature scales. You can mix brands, scale types, and resolution to fit your machine.
Already have an Acu-Rite, NewAll, Anilam, Sargon, or similar console? Don't throw away good name-brand industrial scales. TouchDRO supports most of these scales — including their reference marks — so you can modernize the readout and keep using your existing scales.
TouchDRO works with iGaging Absolute DRO and EZ-View DRO, Mitutoyo Digimatic, and similar capacitive scales. Add a readout anywhere a full-size scale won't fit, and sum quill and knee/head positions into a single Z readout.
