A complete graduated set of 13 bits. All marked RUSSELL JENNINGS. All are bright, clean and sharp. Sizes 4 through 16 which correspond to 1/4 inch to 1 inch. The bits were patented in 1855. The three-tiered box was patented in 1890. I prefer the roll over the box. It takes up less space. they are cheaper to buy. You can toss the roll into a tool  box without fear of it breaking. RUSSELL JENNINGS were bought out by STANLEY in 1944. The best user auger bits ever made!
