U.S. Standard 6FA DE 8" Dual-Wheel Pedestal Grinder

Serial Number: 53718 | Year of Mfg: Circa 1937 | Configuration: Integrated Dust Collection

Overview

Up for sale is a classic piece of American industrial history: a U.S. Standard 6FA DE double-end pedestal grinder. Manufactured by the United States Electrical Tool Co. in Cincinnati during the late 1930s, this "Pre-War" era machine represents the peak of vibration-dampening cast iron design.

This specific unit is the "Deluxe" industrial configuration, featuring a factory-integrated dust collection system built directly into the pedestal. Unlike modern bench grinders, the 6FA is designed for continuous, 24/7 toolroom operation. Its mass ensures that even under heavy load, the machine remains perfectly stable, providing the precision needed for fine tool sharpening and heavy deburring.
