The Brownells 45° Chamfering Cutter breaks the edges of the rifling for a clean bullet exit or chamfers revolver cylinder chamber mouths for quick reloads. This cutter measures 3-1/4″ (8.25cm) long with a 5/8″ (15.8mm) diameter, making it suited for larger barrel and cylinder mouths where precision edge beveling is required. Made of hardened steel, this tool delivers professional-grade performance.
A damaged or poorly-cut muzzle can hurt accuracy, and sharp edges on revolver cylinder chamber mouths can cause rounds to hang up going into the cylinder—a problem when using speedloaders. The cutter features interchangeable muzzle pilots that ensure blade alignment perpendicular to the bore axis, and is useful for facing-off and squaring barrel muzzles after shortening, or for repairing damage on flat muzzle surfaces. this 5/8″ cutter handles the larger-diameter work that standard tools cannot address.
