The BROWNELLS CARBIDE SEMI-AUTO PISTOL SIGHT BASE CUTTER is available in 60° and 65° shoulder angles to match standard Colt factory and various mil-spec 1911 Autos, as well as other sights with similar dovetails.
Designed for use exclusively in a milling machine, the solid carbide cutter is 2 inches long with a 3⁄8 inch diameter shank, offering durability when cutting through hardened steel pistol materials.
The actual cutting diameter of the cutter is .330", requiring multiple passes for installation to accommodate factory variations and milling tolerances.
