About Irwin auger bits

Irwin is an American maker long based in Wilmington, Ohio, and its name is tied above all to solid-center auger bits for brace work. The numbered sizing follows sixteenths of an inch, so a No. 20 measures 1 1/4 inches and a No. 24 measures 1 1/2 inches, and the larger sizes turn up less often than the common middle numbers. Unused stock still in the original box, crisp shank stamps, full lead screw threads, and unsharpened spurs and cutting lips raise value, while pitting, shortened twists from repeated filing, and stripped screws pull it down. Expansive bits should retain both cutters and the adjusting screw.

The 30 sales behind these figures come from Jim Bode Value Guide (23) and Ted Dawson Antique Tools (7), and run from 2020 to 2026; 6 closed in the last twelve months. 112 listings for sets, pairs or lots of Irwin auger bits were left out, because a set's price is not one tool's price.
