Grizzly T33020 Digital Read-Out 3-Axis Mill DRO 15-3/4" x 15-3/4" x 31-1/2" New

The Grizzly T33020 is a 3-axis digital readout kit designed to add precise position tracking to a milling machine. It includes the readout unit, mounting hardware, two 15-3/4 inch linear optical scales, and one 31-1/2 inch linear optical scale for a custom mill installation.

Built for accurate machining, this DRO system offers 5μm resolution, strong repeatability, and functions for pitch circle diameter, line hole positioning, inclined machining, radius work, shrinkage calculation, and error compensation. The sealed aluminum readout housing helps protect internal electronics from dust, fumes, and coolant exposure, while the optical scales are made for smooth, reliable movement in shop environments.

This kit is a practical choice for machinists, fabricators, and shop owners who want clearer measurement feedback and more efficient setup on a manual mill. It is well suited for users looking to improve accuracy, streamline complex layouts, and switch easily between metric and inch readouts.
