JULY BOOM
Lot 50:
Description
A lot of eleven large-diameter twist drill bits designed in the Silver and Deming style, characterized by reduced 1/2-inch shanks. These tools are manufactured from high-speed steel (HSS) for heavy-duty metalworking applications. One bit in the collection is explicitly marked with the size 21/32 and the stamp HS UB USA, indicating production by Union Butterfield in the United States. The remaining bits feature various stamped sizes, including 3/4, 1 1/16, and 1-1/2, though these marks are partially obscured by surface conditions. The set includes one blue plastic protective case.
