DRO Chip Upgrade


Upgrade your old DRO with our new DRO chip.

About the DRO Chip Upgrade

Beginning August 1st, 2021, all DROs will ship with an upgraded chip. This new chip upgrade allows our Digital Readout to function with our ball screw machines as well as our standard leadscrew machines. We also programmed some upgrades based on customer feedback, like having a Metric display on an Inch machine or having an Inch display on a Metric machine.

The new DRO chip has six different modes to choose from based on the machine type, e.g., mill, lathe, leadscrew, or ball screw, and your preference of either inch or metric display on the DRO.

You can order the chip to upgrade your DRO system if you already have a Sherline Digital Readout display. Click on the Instructions tab to learn more about installing the new DRO Chip and the new mode features we have programmed into it.

NOTE: You must make sure you have the correct tach sticker for your machine. Use a 6-pulse (P/N 81510) tach sticker if your machine is a leadscrew machine or a 5-pulse tach sticker (P/N P/N 68060) if your machine is a ball screw machine.

The improper use of machine tools and their accessories can result in serious injury. Before using this tool, thoroughly read the instructions and make sure you understand its proper and safe use.


Always wear safety glasses when operating machine tools.
