This Vintage DETROIT TWIST DRILL CO. Decimal Equivalent Tap Drill, Drill Speed Wheel Chart is made of plastic and in good condition. It is double sided. One side spins to match up number drills #'s 1-59, 61, 63 and fractional 1/2", 1/4" and 3/4" with their Decimal Equivalents. The other side spins to show Tap Drill Sizes for U.S. Standard Thread sizes 1/4" to 2-1/4" and Drill Speeds for those size drills in CAST IRON, SOLF TOOL STEEL AND BRASS. There are no previous owner's names or ID markings on this wheel chart. We have not cleaned or refurbished this chart in any manner, as we leave those decisions up to the eventual buyer.
