Product Description

About the Mill Digital Readout without Electronics Box

This kit was developed for those who already have a digital readout installed on their lathe and wish to add a DRO to their mill without duplicating the electronics box. This cost-saving measure allows you to switch the box back and forth between the mill and lathe.

NOTE: The DRO can be ordered on any new machine as a factory installed option. The digital readout handwheels replace the standard handwheels that would normally come with the machine. If you purchase a machine with factory installed DRO, the regular handwheels are not included. If you purchase the DRO as a separate option and install it yourself, you will have the stock handwheels left over.

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.
