The yokes have been ground on or otherwise modified. They will still hold a 3/16" shank squeeze set and function properly. You will receive the exact tool in this photo or will be contacted if a substitute is necessary. As each tool has slightly different modifications to the yoke, please inspect photo carefully. If you order more than one, the yoke may look different on the other items. The motors were rebuilt prior to our purchase. Our tool mechanics have inspecting, tested and adjusted the tool as necessary. We provide our standard used tool warranty.
