We had this DRO made specially for us and are proud to claim that it is one of the finest DROs on the market today. You will be amazed at the list of features that include: selectable resolution down to 5um, absolute/incremental coordinate display, arc function, line of holes function, angles cuts function, 199 user defined datum points, centering/cutter offset, double sealed scales, inches/millimeters, calculator with trig functions (mills only) and linear error compensation. Our low prices are a reflection of the absence of any "middlemen" in the marketing structure. Without a doubt, this feature packed DRO will fit just about any budget!
